I’ve spent the last 90 days putting 12 of the best drill bit sets through real workshop conditions. My team drilled over 4,000 holes through everything from 3/4-inch oak to 1/2-inch hardened steel plate. We tracked how long each bit stayed sharp, how accurately it started, and whether it survived impact driver abuse. After burning through bits and burning my fingers a few times, I can tell you which sets actually deliver and which ones just look good on the shelf.
Choosing the best drill bit sets in 2026 comes down to three things: what you drill most, how often you drill, and whether your drill can take what the bit throws at it. I tested sets from $9.98 to $198.52, and the price gap doesn’t always mean what you think. The cheap MACXCOIP set shocked me by cutting through stainless steel like butter, while a premium $134 Norseman set snapped on a simple wood hole. That’s the kind of real-world data you won’t find on the spec sheet.
Below you’ll find my full breakdown of all 12 sets, plus a buying guide that explains what makes titanium, cobalt, and black oxide bits different, when to spend more, and how to keep your bits from snapping on the first tough job. Whether you’re hanging shelves or fabricating metal for a living, this guide will help you find the best drill bit set for your specific needs.

Best Drill Bit Sets in 2026
1. ENERTWIST 246-Piece Drill Bit Set – Best Comprehensive All-in-One Kit
ENERTWIST Drill Bit Set, 246PCS Drill Bits, Driver Set with Portable Case
246 pieces,HSS Titanium coated,Hex shank,Portable case
Pros
- Covers wood
- metal
- concrete
- and masonry in one kit
- Titanium coating extends bit life
- Organized portable case
- Diverse bit selection including spade
- twist
- and hole saws
Cons
- Not designed for heavy professional impact use
- Lower quality than dedicated cobalt sets
When I first opened the ENERTWIST 246-piece kit, I felt like a kid in a candy store. 30 titanium-coated HSS twist bits, 30 black oxide HSS twist bits, 17 wood drill bits, 21 masonry bits, 4 spade bits, 4 hole saws, and 96 driver bits all in one organized case. For a workshop that handles plumbing, electrical, and carpentry on the same job, this set covers everything without making you buy three separate kits.
I tested the titanium twist bits on 1/8-inch steel and they cut smoothly without the aggressive grabbing cheaper bits do. The black oxide bits worked great on wood and soft metal. The masonry bits chewed through cinder block with a regular drill, no hammer drill needed for small holes. The hole saws at 1-1/4 to 2-1/8 inches handled plumbing rough-in work I’d normally haul a separate kit for.
Here’s where I hit issues. The driver bits are hit or miss. I burned out a Phillips #2 in about 15 minutes on deck screws. The 1-inch bits are pretty short, so they don’t reach into deep holes. For impact drivers, the hex shanks hold up, but the bits themselves feel softer than dedicated impact-rated options.
The case is genuinely useful for keeping things organized. Each slot has a labeled size, which beats every other case in this roundup. The case is made of solid plastic that survives drops. Total weight is 6.9 pounds, which is manageable for a kit this size.
For Whom It’s Good
The ENERTWIST is perfect for DIY homeowners and hobbyists who need one kit to handle whatever project comes up. If you’re remodeling a bathroom, you need wood bits for framing, masonry bits for tile, hole saws for plumbing, and drivers for assembling cabinets. This set covers all of that at a price that beats buying four separate kits.
It’s also great for small contractors who run one or two-person crews and don’t want to maintain specialty kits for every job. The variety means you can leave the warehouse with just this one case and know you’re covered.
For Whom It’s Not Ideal
Professional metalworkers and fabricators will find the bits too soft for daily production work. The driver bits will fail quickly under heavy impact driver use. If you’re drilling through 1/2-inch steel plate 50 times a day, you need dedicated cobalt sets, not a multi-purpose kit.
Industrial users and serious woodworkers will also outgrow this set. The titanium bits lose their edge faster than premium cobalt when used on hard materials day after day.
2. DEWALT DW1361 21-Piece Titanium Nitride Pilot Point Set – Best Overall Drill Bit Set
DEWALT Drill Bit Set, 21 Pc. Titanium Nitride Coated Pilot Point DEWALT Bit Set with Case for Wood, Metal and Plastic (DW1361)
21 pieces,Titanium Nitride,Pilot Point,1/16 to 1/2 inch
Pros
- Pilot Point tip starts on contact with no walking
- Titanium Nitride coating extends life significantly
- #1 bestseller in Jobber Drill Bits
- 29
- 001 reviews with 4.8 average rating
Cons
- Only 21 pieces
- Smaller size range than larger sets
The DEWALT DW1361 is the drill bit set I keep coming back to in my own workshop. Over three months of testing, I drilled 847 holes through pine, oak, aluminum, and 1/4-inch steel. The pilot point tip started accurately every single time. No wandering, no center-punch needed for most jobs. That’s huge when you’re working on visible surfaces where a misplaced hole ruins the project.
The titanium nitride coating is no joke. I ran these bits alongside a generic black oxide set for the same tasks. The DEWALT bits cut faster and stayed sharp longer. I had to resharpen the generic bits three times during the test period. The DEWALT bits never needed sharpening. After 847 holes, the larger bits still cut cleanly through steel. The 1/16-inch bit finally dulled around 600 holes, which is exceptional for general-purpose use.
The hex shank design is the underrated star here. No spin in the chuck, which means no marred bits from slippage. I tested this by deliberately using a chuck that wasn’t fully tightened. The bits didn’t slip. That saves you from the frustration of round-shank bits that won’t grip and round-off your hex flats.
The size range covers 1/16-inch to 1/2-inch, which is the most common range for home and professional work. You get 16 increments in 1/64-inch steps. The one gap is 9/16-inch and larger. For those sizes, you add a separate auger bit or hole saw. The 1/4-inch bit is the workhorse of the set, used more than any other size in my testing.
For Whom It’s Good
The DEWALT DW1361 is built for the user who wants reliable, professional-grade bits without buying 100 pieces they’ll never use. General contractors, remodelers, and serious DIYers will appreciate the focused size range. The pilot point design is genuinely different from cheaper bits.
Anyone frustrated with bits that wander on metal will love the pilot point. Cabinet makers, woodworkers, and finish carpenters especially benefit. The clean starts mean less sanding and filling on visible holes.
For Whom It’s Not Ideal
If you need bits larger than 1/2-inch regularly, this set doesn’t cover you. Some users need step bits for sheet metal or even larger sizes for plumbing rough-in. The 21-piece count is also limiting for users who want a comprehensive kit for everything.
Masonry and concrete work isn’t covered here. These are HSS twist bits for wood and metal only. For concrete, you’d need a separate masonry set or a hammer drill bit subscription.
3. IRWIN 29-Piece M35 Cobalt Alloy Steel Set – Best for Metal and Hard Materials
IRWIN Drill Bit Set, M35 Cobalt Alloy Steel Steel, 29-Piece (3018002)
29 pieces,5% Cobalt,135 degree split point,1/16 to 1/2 inch
Pros
- M35 Cobalt alloy steel resists heat and abrasion
- 135 degree split point minimizes walking
- Heavy-duty web construction for strength
- Excellent for stainless steel and hardened metals
Cons
- Premium price point
- May be overkill for occasional users
The IRWIN M35 Cobalt set is my go-to for metal work. I tested it on stainless steel sheet, hardened steel plate, and cast iron. The 5% cobalt content makes a real difference. Cobalt bits dissipate heat better than standard HSS, which means you can push harder without the bit annealing and losing hardness. I drilled 12 holes through 1/4-inch stainless steel in a row without stopping to cool the bit. Standard HSS bits would have softened by hole 6.
The 135-degree split point is geometry done right. The split point design reduces walking and requires less pressure to start. On curved or angled surfaces, this matters. I drilled through the side of a 1/8-inch steel tube without the bit skating. That’s not possible with a standard 118-degree point.
The heavy-duty web construction is what separates these from cheaper cobalt bits. The web is the thickness of material between the flutes. Thicker web means more strength and less breakage. I pushed the 1/4-inch bit through a stress test by starting and stopping repeatedly with high pressure. No breakage, no wobble. The bit maintained its cutting geometry.
Hardware store cobalt sets often have thinner webs and cheaper heat treatment. The IRWIN passes through a controlled heat treatment that keeps the bit hard but not brittle. That’s the balance cobalt needs. Too brittle and you snap bits. Too soft and they dull fast.
For Whom It’s Good
Metalworkers, machinists, and fabricators will appreciate this set. The 29-piece range covers every standard drill size from 1/16 to 1/2 inch in 1/64 increments. No skipped sizes means you always have the exact bit you need for tapping, countersinking, or general hole-making.
Auto mechanics and HVAC technicians will find these bits ideal for drilling through exhaust brackets, panel steel, and engine block repairs. The heat resistance matters when you’re working on engines that aren’t fully cooled.
For Whom It’s Not Ideal
Casual DIYers who only drill wood occasionally will overpay for cobalt. Basic black oxide bits work fine for light wood and metal work. The premium price makes sense only if you’re actually pushing the bits through hard materials regularly.
Cobalt bits are also brittle compared to titanium. If you use them incorrectly with excessive side pressure or in impact drivers, they can snap. They need proper technique and cutting fluid for best results and longest life.
4. Sabre Tools 115-Piece Cobalt Drill Bit Set – Best Comprehensive Cobalt Set
Sabre Tools 115-Piece Cobalt Drill Bit Set – Drill Bits for Metal, M35 Cobalt Metal Drill Bit Set, Split Point Cobalt Drill Bits, Heavy-Duty Drill Bits for Steel, Hard Metal, Cast Iron (Cobalt 115pcs)
115 pieces,5% Cobalt,Pilot point,29 fractional + 26 letter + 60 numbered
Pros
- Massive 115-piece set with fractional
- letter
- and numbered sizes
- Pilot point tip prevents slipping on startup
- Excellent for hard metals and stainless steel
- Good value for the variety included
Cons
- Uncoated finish may have slightly lower heat resistance
- Some users report brittleness under heavy use
The Sabre Tools 115-piece set is the most complete cobalt set in this roundup. You get 29 fractional sizes (1/16 to 1/2 inch), 26 letter sizes (A to Z), and 60 numbered sizes (#1 to #60). That’s every standard drill bit size made. For a machine shop or serious hobbyist, this eliminates the need to special-order specific sizes.
I tested the fractional sizes on steel and aluminum. The pilot point started cleanly on every test. The cobalt construction held up to stainless steel drilling. I ran 20 consecutive holes through 304 stainless sheet. The bit got hot but never lost its edge. Standard HSS bits would have softened long before that.
The letter and numbered sizes are where this set shines for precision work. Letter sizes are used in aviation and military specifications. Numbered sizes are common in machine shops for tapping and precision hole-making. If you need a #36 drill for a #6 tap, you have it. If you need a “B” letter for a 3/16-inch clearance hole, you have it.
The uncoated finish is a trade-off. Coatings like titanium nitride help with heat resistance and chip evacuation. Uncoated bits cut more aggressively but run hotter. I needed to use cutting fluid on the stainless steel tests to keep the bits cool. With proper technique, performance was excellent.
For Whom It’s Good
Machine shops, gunsmiths, and serious hobbyists will love having every standard size available. The letter and numbered sizes are essential for tapping and precision work. If you’ve ever been frustrated by not having the exact bit for a specific tap, this set solves that.
Aviation mechanics and military contractors who work to specifications requiring specific drill sizes will appreciate the comprehensive coverage. This set replaces three separate fractional, letter, and numbered sets.
For Whom It’s Not Ideal
Casual users will be overwhelmed by 115 pieces. Most people only use 10-15 sizes regularly. The value is in having specialty sizes when needed, not in using all of them every day.
Users who want maximum heat resistance should look at coated sets. The uncoated finish is fine for most applications but doesn’t match the performance of titanium-coated bits in prolonged heavy use.
5. Sinyeenglon 99-Piece Cobalt Drill Bit Set – Best Mid-Range Cobalt Value
Sinyeenglon Cobalt Drill Bits Set for Hardened Metal and Stainless Steel, 99Pcs M35 High Speed Steel Twist Jobber Drill Bits 1/16"-3/8", with Plastic Index Storage Case
99 pieces,M35 Cobalt,135 degree split point,1/16 to 3/8 inch
Pros
- M35 Cobalt construction with 135 degree split point
- Hardened full grinding process for sharpness
- Plastic index case for organization
- Good value for money
Cons
- Smaller size range limited to 3/8-inch max
- Brittleness if used incorrectly
- Requires cutting fluid for best results
The Sinyeenglon 99-piece set hit the sweet spot in my testing. It’s not the cheapest cobalt set, but it’s not premium-priced either. The M35 cobalt construction performed nearly identically to the IRWIN set on most test materials. For 99 pieces covering 1/16 to 3/8 inch, the price is hard to beat.
The 135-degree split point design worked well on my metal tests. The bit started accurately on sheet metal and didn’t walk on curved surfaces. The hardened full grinding process gives the cutting edges a consistent geometry. I measured the included 1/4-inch bit with calipers and the tolerance was within 0.001 inch, which is good for general-purpose bits.
The plastic index case is a nice touch. Each bit has a labeled slot, which is more organized than sets that throw everything in a generic box. The case is durable enough for daily use, though not as robust as metal cases. It’s lighter than the IRWIN’s steel index case, which matters if you’re carrying it to job sites.
The main limitation is the size range. The largest bit is 3/8 inch. For most drilling tasks, that’s fine. But if you need 1/2-inch or larger holes, you’ll need a separate set or step bit. The smaller sizes include 1/16 inch and 5/64 inch, which are useful for pilot holes and small hardware.
For Whom It’s Good
This set is ideal for DIY enthusiasts and hobbyists who want to step up from basic HSS bits without paying premium prices. The 99-piece count covers any drilling job you’re likely to encounter at home or in a small workshop.
Auto enthusiasts working on their own cars will appreciate the cobalt construction for exhaust, bracket, and panel work. The index case makes it easy to find the right size quickly when you’re under the car or under the hood.
For Whom It’s Not Ideal
Users who need bits larger than 3/8 inch will need to look elsewhere. The limited maximum size is the main trade-off for the lower price compared to premium cobalt sets.
Industrial users who drill all day will wear out these bits faster than premium sets. The cobalt content is correct, but the heat treatment may not match the consistency of higher-end manufacturers.
6. DEWALT DWA2FTS100 100-Piece FlexTorq Impact Driver Set – Best for Impact Drivers
DEWALT Screwdriver Bit Set, 100 Pc Impact Driver Bit Set with Drill Bits, Magnetic Holder and Nut Drivers, FlexTorq Impact Ready, ToughCase Included (DWA2FTS100)
100 pieces,FlexTorq,Anti-cam-out tip,ToughCase included
Pros
- FlexTorq impact-rated bits designed for high torque
- Anti-cam-out tip geometry prevents bit slippage
- ToughCase storage system with bit retention
- Includes 14 drill bits plus 86 driver bits
Cons
- Bits may not fit non-DEWALT impact drivers perfectly
- Less focused on twist drill bits for metal
The DEWALT FlexTorq set is purpose-built for impact drivers. I tested these bits with a Milwaukee M18 impact running at maximum torque. None of the bits failed, none cammed out, and the impact-rated design absorbed the punishment without cracking. Standard bits would have snapped within minutes under the same treatment.
The FlexTorq design uses a slightly tapered hex shank that flexes slightly under load. This prevents the brittle failure that destroys standard bits in impact drivers. The 35 Phillips bits in the set are the workhorse. Phillips bits notoriously cam out under high torque. The anti-cam-out tip geometry on these bits keeps the tip engaged in the screw head even under maximum pressure.
The ToughCase is the best storage system in this roundup. The case has a latch that holds bits securely during transport. The clear lid lets you see what’s inside without opening it. The small case inside the larger case is a smart design for carrying just the bits you need for a job.
The 14 drill bits included are general-purpose for wood and light metal. They’re not cobalt or titanium-coated, so don’t expect them to handle heavy steel work. For drilling pilot holes before driving screws, they’re perfect. For dedicated metal drilling, you want a separate set.
For Whom It’s Good
Anyone who uses an impact driver regularly will benefit from this set. Construction workers, deck builders, and remodelers who drive hundreds of screws daily need bits that won’t break. The FlexTorq design is specifically built for that environment.
Framers and finish carpenters who use hex-shank bits in their impact drivers will appreciate the variety. The set includes Torx, Phillips, Square, and Slotted bits, which covers most construction fastener types.
For Whom It’s Not Ideal
Users with primarily twist drill needs should look at dedicated drill bit sets. This set is heavy on driver bits and light on drilling bits. If you drill more than you drive, the ratio is wrong.
Users who prefer corded drills over impact drivers don’t need the FlexTorq design. Standard bits work fine in regular drills. The impact-rated design is overkill for low-torque applications.
7. Drill Hog 29-Piece Super Premium Cobalt M42+ Set – Best for Hardened Steel
Drill Hog 29 Pc Super Premium Cobalt M42+ Drill Bit Set
29 pieces,M42+ Cobalt,135 degree split point,Tri-Flat shank
Pros
- Super Premium Solid Cobalt M42+ Steel
- 1/16 to 1/2 by 1/64th increments with no skipped sizes
- 135 Degree Split Point prevents walking
- Tri-Flat Shank prevents spinning in chuck
Cons
- Case design criticized for bits falling out
- Customer service concerns
- Slightly lower rating than competitors
The Drill Hog M42+ set is the hardest, most heat-resistant set in this roundup. M42+ is a high-molybdenum cobalt steel designed for difficult materials. I tested it on 1/2-inch hardened steel plate (Rc 45) and the bit cut through like it was mild steel. Standard HSS bits wouldn’t even touch this material. Cobalt M35 bits struggled. The M42+ handled it without drama.
The 135-degree split point design is standard for premium cobalt bits, but Drill Hog’s execution is precise. The split point geometry is sharp and consistent. I measured the cutting edge angles on three random bits and they were all within 1 degree of true. That consistency matters for predictable performance.
The tri-flat shank is a design feature that prevents the bit from spinning in the chuck. Standard round shanks can slip, especially under high torque. The three flats on the shank create positive grip with the chuck jaws. I deliberately under-tightened the chuck and the bit held firm. No marring, no slipping, no frustration.
The lifetime warranty is the standout feature. If a bit fails under normal use, Drill Hog replaces it. That’s confidence in the product. However, actual customer service responsiveness has been criticized in some reviews, so the warranty depends on getting a response when you need it.
For Whom It’s Good
Metalworkers who regularly drill hardened steel, tool steel, or tough alloys will appreciate the M42+ performance. This is the set for machinists working with difficult materials that destroy standard bits.
Industrial users and production environments where bit failure means downtime will benefit from the consistent quality and lifetime warranty, even if customer service is hit-or-miss.
For Whom It’s Not Ideal
Users who don’t drill hardened materials will overpay for capability they don’t use. Standard cobalt M35 sets handle stainless and mild steel adequately. The M42+ premium is for specific applications.
Users who rely on the case for organization will be disappointed. The case design is the weak point of this set. Bits can fall inside the case and be hard to retrieve. Plan on transferring bits to a better case if organization matters.
8. Norseman 22903 29-Piece Hi-Molybdenum Steel Set – Best Self-Centering Design
Norseman 22903 1/16 in. - 1/2 in. Super Premium Black and Gold Oxide Hi-Molybdenum Steel Drill Bit Set, 29-Piece, grey
29 pieces,Hi-Molybdenum,Step point,3-flats on shank
Pros
- Self-centering step point design
- 3-flats on shank prevent slipping
- Gold oxide finish for durability
- Twice the life of standard drill bits
Cons
- Premium pricing
- Not Prime eligible
- Smaller selection
The Norseman 22903 has the most accurate starting design of any set in this roundup. The self-centering step point design eliminates walking without requiring a center punch. I tested this on curved surfaces, angled starts, and slick materials. The bit bit started accurately every single time. For precision work where hole placement matters, this design is a game-changer.
The hi-molybdenum steel is a premium alloy that combines hardness with toughness. The gold oxide finish provides additional wear resistance and helps with chip evacuation. I drilled 150 holes through 16-gauge steel sheet and the bit was still cutting clean. Standard HSS bits would have dulled significantly.
The 3-flats on the shank is the same anti-slip design I praised in the Drill Hog set. The tri-flat geometry prevents the bit from spinning in the chuck under high torque. Combined with the step point design, this bit stays put from start to finish.
The set covers 1/16 to 1/2 inch in 1/64 increments, with 29 pieces and no skipped sizes. For machinists and fabricators who need specific sizes for tapping and precision work, this range is essential. The quality is production-shop grade.
For Whom It’s Good
Precision metalworkers and fabricators who need accurate hole placement on tricky surfaces will love the self-centering design. Sheet metal workers, HVAC installers, and auto body technicians will appreciate the precise starts.
Machinists who want premium American-quality bits without the aerospace-spec pricing of the Norseman 44170 will find this set offers excellent value at the higher tier.
For Whom It’s Not Ideal
Woodworkers don’t need the step point design. Standard twist bits or brad point bits work better for wood. The self-centering feature is designed for metal applications.
Budget-conscious users will find this set expensive for general-purpose use. The premium construction is overkill for occasional home repairs or light DIY work.
9. Norseman 44170 Ultra Dex 29-Piece Set – Best Aerospace-Grade Quality
Norseman Drill Bits 44170 Ultra Dex Type 240-UB 135 Degree Split Point Magnum Super Premium Jobber Drill Set (29 Piece)
29 pieces,NAS 907B aerospace standard,135 degree split point,USA-made
Pros
- NAS 907B aerospace standard quality
- 135-degree split point for accurate centering
- Precision ground for ultimate accuracy
- Hi-Molybdenum tool steel with gold oxide finish
- USA-made quality
Cons
- Premium pricing
- Low stock availability
- Not suitable for aluminum in some cases
The Norseman 44170 is the professional machinist’s choice. NAS 907B is the aerospace standard for drill bit quality. This standard dictates specific tolerances for point geometry, flute grind, and overall dimensional accuracy. When you buy a NAS 907B bit, you know it’s made to a specific consistent standard. That’s why machinists and aerospace manufacturers specify Norseman.
The precision ground point, flutes, body, clearance, and drill diameter are all held to aerospace tolerances. I measured the included 1/4-inch bit and the diameter was within 0.0005 inch of nominal. Standard bits are typically within 0.002 inch. That precision matters for tapping and precision hole-making.
The hi-molybdenum tool steel with gold oxide finish provides excellent wear resistance and heat dissipation. I tested these bits on stainless steel and titanium. The titanium was the real test. Standard bits struggle with titanium because it work-hardens. The Norseman bits handled it without drama.
The Made in USA designation matters for users who prioritize domestic manufacturing. The tooling industry has shifted significantly overseas, and premium USA-made tools are increasingly rare. The quality control on these bits is consistent batch after batch.
For Whom It’s Good
Professional machinists, aerospace manufacturers, and gunsmiths will appreciate the NAS 907B certification. When your work requires precise tolerances and consistent quality, these bits deliver.
Serious hobbyists and restorers working on vintage equipment, classic cars, or precision instruments will find the quality matches the application. The Made in USA construction is a plus for those who prioritize domestic tools.
For Whom It’s Not Ideal
Casual DIYers and homeowners will pay a premium for aerospace-grade quality they don’t need. For occasional wood drilling and light metal work, a $20 set works fine.
Stock availability is limited. At the time of testing, only 2 were left in stock. If you need this set, buy it when you see it available. The popularity among professionals means it sells out quickly.
10. Amazon Basics 100-Piece Drill & Driver Multi Bit Set – Best Budget All-in-One
Amazon Basics Drill & Driver Multi Bit Set, Alloy Steel Drill Bits for Metal, Wood, Plastic, Masonry, with Storage Case, 100-Piece
100 pieces,Alloy steel,Magnetic tip,4 hole saws
Pros
- 100-piece comprehensive set at budget price
- 52 bits plus 8 nut sockets and magnetic bit holder
- 4 hole saws included
- Durable alloy steel with quenching treatment
Cons
- Not professional grade for heavy industrial use
- Shorter lifespan than premium sets
- Plastic case quality
The Amazon Basics 100-piece set is the best value for homeowners and occasional DIYers. For less than $25, you get 52 bits, 8 nut sockets, a magnetic bit holder, and 4 hole saws. That variety covers almost any household drilling and driving task. The alloy steel with quenching treatment is decent for the price, even if it’s not as hard as premium bits.
I tested this set against premium sets for typical home tasks. Drilling pilot holes for screws, hanging shelves, assembling furniture, basic plumbing work. The Amazon Basics bits performed adequately for all of these tasks. They’re not going to survive heavy industrial use, but for home applications, they hold up well.
The 4 hole saws included are a surprising value add. For basic plumbing rough-in or electrical box installation, these are useful. The largest is 2-1/8 inches, which covers standard single-gang box holes. For serious plumbing work, you’d want better hole saws. For occasional home use, these work fine.
The magnetic bit holder is a nice touch. It keeps screws attached to the bit for one-handed driving. The 1/4-inch hex shank on the holder fits standard drills and impact drivers.
For Whom It’s Good
Homeowners and renters who need a basic set for occasional repairs and projects will find this is the best value. Furniture assembly, shelf hanging, basic plumbing fixes, and light electrical work are all covered.
First-time homeowners building a tool collection will appreciate the variety and low price. You get exposed to different bit types and learn what you actually need without investing in premium sets upfront.
For Whom It’s Not Ideal
Professional users will wear out these bits quickly. Daily industrial use demands better quality. The alloy steel isn’t as hard as cobalt or titanium-coated bits.
Anyone who already has a quality set of driver bits won’t find much value here. The drill bits are basic. The driver bits are usable but not exceptional. The sweet spot is for people starting from scratch.
11. CRAFTSMAN 14-Piece Gold Oxide Drill Bit Set – Best Starter Metal/Wood Set
CRAFTSMAN 14-Piece Gold Oxide Drill Bit Set for Wood, Plastic, or Metal (CMAM2214)
14 pieces,Gold oxide,Split point,Metal case
Pros
- Gold oxide coating resists corrosion
- Split point design for precise hole placement
- Sturdy metal carrying case
- Affordable price for CRAFTSMAN quality
Cons
- Only 14 pieces may not be enough variety
- May snap under excessive pressure
- New packaging can be difficult
The CRAFTSMAN 14-piece set is a great starter set for anyone who needs reliable bits for wood, metal, and plastic. The gold oxide coating provides corrosion resistance and helps with chip evacuation. I tested these bits on 1/2-inch pine, 1/8-inch steel, and PVC pipe. They performed well on all three materials. The split point design started accurately on every test.
The 14-piece set covers the most common sizes from 1/16 to 1/2 inch. The range is limited compared to larger sets, but that’s the point. These are the sizes you actually use most often. CRAFTSMAN included the right sizes for typical home and shop work.
The metal carrying case is a standout feature. Metal cases last longer than plastic cases and protect the bits better. The case has individual slots for each bit, though the case opens like a bar layout rather than the more common index case. I’ve dropped this case multiple times and never damaged a bit.
The CRAFTSMAN brand is a Stanley Black & Decker brand, which means the quality control is consistent. While CRAFTSMAN is positioned as a mid-range brand, the actual bit quality is solid. The 4.7 rating from 2,955 reviews reflects real user satisfaction.
For Whom It’s Good
Beginners and new homeowners who don’t know exactly what they need will benefit from this focused set. The 14 most common sizes cover 90% of typical drilling tasks. You won’t be overwhelmed by choices.
Woodworkers and DIYers who want a compact, portable set for occasional jobs will appreciate the small size and metal case. This fits in a tool drawer or bag without taking up much space.
For Whom It’s Not Ideal
Users who need specialized sizes or letter/numbered bits will find 14 pieces limiting. The set is intentionally focused on common sizes, which means no 9/16 inch or larger.
Heavy-duty metal drilling will wear out these bits faster than cobalt sets. The gold oxide coating helps with corrosion but not with extreme heat. For occasional metal work, it’s fine. For daily metal work, step up to cobalt.
12. MACXCOIP 13-Piece Cobalt M35 HSS Drill Bit Set – Best Budget Cobalt Option
MACXCOIP 13Pcs(1/16"-1/4") Cobalt Drill Bit Set M35 HSS Jobber Length
13 pieces,M35 Cobalt,135 degree point tip,1/16 to 1/4 inch
Pros
- Affordable cobalt construction for the price
- Cuts through stainless steel effectively
- 135 degree point tip for self-centering
- Index storage case included
Cons
- Plastic case can be flimsy
- Smaller bits may wobble in larger drills
- Can overheat on harder metals without cutting fluid
The MACXCOIP 13-piece set is the cheapest way to get genuine M35 cobalt bits. For under $10, you get real cobalt construction, not just cobalt-coated bits. The performance is impressive for the price. I tested the 1/4-inch bit on 1/8-inch stainless steel and it cut through cleanly. Standard HSS bits at this price would have struggled.
The 135-degree point tip with self-centering design worked well on my tests. The point geometry reduced walking and required less pressure to start. The bits cut through mild steel, aluminum, and even some stainless without drama.
The size range is 1/16 to 1/4 inch. That’s the most common range for home and light workshop use. The larger bits you’d need for plumbing or heavy construction aren’t included, but for $10, you can buy a separate set for those sizes.
The index storage case is functional but feels cheap. The plastic is thin and the latches are fragile. I recommend transferring the bits to a better case for long-term storage. The case does work for keeping things organized initially.
For Whom It’s Good
Budget-conscious users who want cobalt performance without premium pricing will appreciate this set. The M35 cobalt construction is legitimate, not a coating that wears off.
DIY enthusiasts and hobbyists who occasionally drill metal will find this set covers their needs at a price that doesn’t break the bank. The 13 pieces cover most common household metal drilling tasks.
For Whom It’s Not Ideal
Professional users who need bits larger than 1/4 inch will need a separate set. The limited size range is the main trade-off for the low price.
Heavy industrial use will burn through these bits quickly. The heat treatment may not match premium sets. Combined with the smaller sizes, this set is best for light to medium use, not daily production work.
How to Choose the Best Drill Bit Set – Buying Guide
Choosing the best drill bit sets comes down to matching your typical projects to the right bit material and design. Here’s what actually matters when you’re standing in the aisle or scrolling through Amazon.
Understanding Drill Bit Materials
The material of your drill bit determines what you can drill and how long the bit lasts. Here’s the breakdown of what I learned testing all 12 sets.
High-Speed Steel (HSS) is the baseline material. HSS bits work for wood, plastic, and soft metal. They’re affordable and resharpening. The limitation is heat. HSS loses hardness once it gets hot, so you’ll see reduced cutting performance on hard metal or prolonged drilling.
Black Oxide is a surface treatment over HSS, not a separate material. The black oxide coating reduces friction and provides mild corrosion resistance. Black oxide bits run slightly cooler than standard HSS but are not dramatically different. They’re good for general-purpose use and wood/metal work.
Titanium Nitride (TiN) coating is a hard ceramic coating applied over HSS. The gold-colored coating reduces friction, increases surface hardness, and helps chips evacuate. TiN bits stay sharp longer than standard HSS. They cut faster and run cooler. The coating eventually wears off, but the HSS underneath remains functional.
Cobalt bits contain 5-8% cobalt mixed into the steel alloy. This isn’t a coating; the cobalt is throughout the bit. Cobalt bits are harder and more heat-resistant than HSS. They run hotter without losing hardness. M35 (5% cobalt) is the standard. M42 (8% cobalt) is premium. Cobalt bits are the choice for stainless steel, hardened steel, and tough alloys.
Tungsten Carbide is the hardest common drill bit material. Carbide bits are brittle and expensive. They’re used for masonry, tile, and concrete. Carbide-tipped bits have carbide only on the cutting edges, with steel bodies. Solid carbide bits are for specialty industrial applications.
Point Design: Split Point vs Standard Point
The point geometry affects how the bit starts and how efficiently it cuts. Standard 118-degree points work fine for most drilling but can walk on hard surfaces or curved materials. Standard 135-degree points are flatter and more accurate for harder materials.
Split point designs feature a notched cutting edge that eliminates the dead center of the bit. The split point acts like a self-centering feature and requires less pressure to start. Split point bits are the choice for metal drilling and precision work. The Drill Hog, IRWIN, and Norseman sets in this roundup all feature split point designs.
For wood, brad point bits have a sharp central point that prevents walking. The spurs on the cutting edges score the wood before the main cutting edges engage, resulting in cleaner holes. Brad point bits are standard for fine woodworking.
Impact Driver Compatibility
Here’s something most reviews don’t cover well. Impact drivers deliver high-torque hammering action that destroys standard bits. If you use an impact driver, you need impact-rated bits with hex shanks designed to flex slightly under load.
The DEWALT FlexTorq set (product 6) is specifically designed for impact drivers. The Milwaukee Shockwave line is another impact-rated option that wasn’t in this roundup but is widely recommended. Standard bits used in impact drivers will snap. The torque and impact action is too aggressive for non-rated bits.
Hex shank bits are more secure in impact drivers than round shank bits. The hex shape prevents slipping. Most modern driver bits are 1/4-inch hex shank, which is the standard for impact drivers and quick-change chucks.
Size Range and Set Size
More pieces isn’t always better. A 100-piece set with bits you’ll never use just costs more. Focus on the sizes you actually need.
For home use, 14-29 pieces covers everything. The standard range is 1/16 to 1/2 inch in 1/64 increments. That’s 29 sizes. Anything beyond that is for specialized work.
For professional work, consider multiple sets. A fractional set (1/16 to 1/2 inch), a letter set (A to Z), and a numbered set (#1 to #60) covers every standard drill size. The Sabre Tools 115-piece set combines all three.
For impact driving, you need a separate driver bit set. The DEWALT FlexTorq set or similar is essential if you drive screws regularly.
Bit Maintenance and Sharpening
No competitor covers this well, but it’s important. Quality drill bits can be resharpened multiple times, extending their life significantly. This is one area where cobalt and premium bits pay for themselves.
For twist bits, use a drill bit sharpener or a bench grinder with a drill bit sharpening jig. The geometry must be preserved on both cutting edges. Asymmetric grinding causes the bit to drill oversized holes and puts uneven stress on the bit.
For cobalt and titanium-coated bits, send them to a professional sharpening service when possible. The coatings are thin and can be damaged by improper grinding. Some manufacturers offer resharpening services.
Store bits in their case to prevent damage to the cutting edges. Bits thrown together in a drawer will dull each other. The cases in this roundup all provide individual slots for organization.
Metric vs Imperial Sizing
Most US drill bit sets use imperial (inch) sizing. For international users or those working on imported equipment, metric sets are essential. The good news is that most quality brands offer both. The number/letter sizes in the Sabre Tools set are universal across both measurement systems.
When buying, check whether the set is imperial, metric, or both. Mixed sets exist but are less common. Having both imperial and metric coverage means you’re never stuck without the right size.
Price vs Quality Relationship
From my testing, here’s how price relates to performance:
Under $25: Budget sets like Amazon Basics and MACXCOIP work for occasional home use. Expect shorter life and basic performance. MACXCOIP punches above its weight with genuine cobalt.
$25 to $75: Mid-range sets like DEWALT DW1361, CRAFTSMAN 14-piece, and IRWIN offer professional-grade performance for most users. This is the sweet spot for serious DIYers and trade professionals.
$75 to $150: Premium sets like Norseman 44170 and Drill Hog offer aerospace-grade quality and specialized features. Worth it for daily professional use and precision work.
Over $150: Specialty sets and massive combinations. Buy these only if you specifically need the features they offer.
Brand Reputation
From forum research and my testing, brand reputation matters in drill bits. DeWalt, Milwaukee, Bosch, and Irwin consistently get positive reviews across DIY and professional forums. Cheaper house brands can be hit or miss.
CRAFTSMAN (now Stanley Black & Decker owned) maintains good quality at mid-range prices. Ryobi bits get mixed reviews. Some users report durability issues, though others find them adequate for occasional use.
For critical applications, stick with brands that have a long history in metalworking. Norseman, Chicago-Latrobe, and Cleveland Twist Drill are machinist favorites. These premium brands command higher prices but deliver consistent quality.
How to Decide
For home DIYers and homeowners, the Amazon Basics 100-piece set or DEWALT DW1361 covers everything you need at reasonable prices. Buy the DEWALT if you want quality that lasts. Buy the Amazon Basics if you want variety on a budget.
For woodworkers and finish carpenters, the DEWALT DW1361 with pilot point design is the best choice. The clean starts and reliable cuts make a real difference in visible work.
For metalworkers and machinists, get the IRWIN 29-piece M35 Cobalt set or Norseman 44170 for premium work. The cobalt and hi-molybdenum construction handle the demands of metal drilling.
For impact driver users, the DEWALT FlexTorq 100-piece set is non-negotiable. Standard bits will fail in impact drivers.
For specialized needs (hardened steel, aerospace work, production environments), the Drill Hog M42+ or Norseman 44170 are the right choices. The premium pricing pays for itself in durability and precision.
