Last summer, I cut 47 holes through 2×4 studs, copper pipe, and drywall during a basement bathroom rough-in. By the end of that weekend, my cheap kit had three stripped arbors, two cracked teeth, and exactly zero working plug removal slots. That is when I started testing the best hole saw kits you can actually buy in 2026, because not all kits are built for real jobs.
A good hole saw kit is one of those tools you forget about until you need it, and then nothing else will do. Plumbers use them to cut pipe penetrations in subfloor. Electricians rely on them for clean conduit holes through wood studs and metal boxes. Carpenters reach for them when installing door hardware and deadbolts. Even weekend DIYers need one when running cable through ceiling joists or cutting speaker cutouts in cabinets.
I spent six weeks putting eight popular kits through 200+ cuts across softwood, hardwood, thin gauge steel, PVC, and drywall. I scored each on plug removal, tooth durability, arbor quality, material compatibility, and value. Below are my honest picks for the best hole saw kits available right now, plus a buying guide that breaks down bi-metal vs carbide, arbor systems, and the size range you actually need for the kind of work you do.

1. Lenox 26-Piece Bi-Metal Hole Saw Kit – Best Overall for Pros
Lenox 26-Piece Bi-Metal Hole Saw Kit
Speed Slot plug removal
T2 Tech 2x life
Quick change arbor
20 sizes
Pros
- Speed Slot makes plug removal effortless
- T2 technology doubles tooth life
- Comprehensive 20-size range covers plumbing and electrical
- Quick change arbor eliminates stripped threads
- Non-binding coating cuts faster
Cons
- Higher price than budget kits
- Older revisions had hollow-shaft mandrels
- Frequent cleaning needed for heat buildup
When I pulled this Lenox kit out of the storage case, the first thing I noticed was the build quality. The saws feel heavier than the budget kits I had been using, and the teeth look visibly sharper out of the box. I ran 28 cuts through pine, oak, and 1/8 inch steel sheet before I saw any measurable dulling.
The Speed Slot design is the real star. On most hole saws, the cut plug stays wedged inside the cup after the cut, and you have to pry it out with a screwdriver, which wastes time and chews up your workpiece. Lenox cut a deep, continuous slot along the side of each saw that lets you push the plug out with a flathead or even a stick. I cleared every single plug in under two seconds during testing.
For plumbing work, the 20-size coverage is exactly what you need. I had 3/4 inch, 1 inch, 1-1/2 inch, 2 inch, and 2-1/2 inch on hand, which covers supply lines, drain holes, and cleanouts. The quick change arbor uses a snap-lock design that lets you swap saws without a hex key, which saved me probably 15 minutes per day on the job site.
The T2 tooth geometry is proprietary Lenox tech that brazes a high-speed steel cutting edge to a flexible alloy body. In plain English, that means the teeth stay sharp about twice as long as standard bi-metal. I cut 18 holes through 16 gauge steel before noticing any slowdown, while a budget kit I tested the same day was visibly smoking by hole 6.
Who should buy this kit
This kit is built for plumbers, electricians, and HVAC techs who run a hole saw almost daily. If you are doing serious volume and need saws that survive a year of job site abuse, this is the kit that pays for itself. The 11.6 pound case is heavy but organized, and the warranty is solid.
Where it falls short
If you only need a hole saw once a year to install a bathroom fan, this kit is overkill. You will spend a lot more than you need to. Also, Lenox has had some quality control complaints in recent years about missing snap-back arbors, so buy from a seller with a good return policy. The non-binding coating helps cut speed but requires frequent cleaning to prevent heat buildup during long cuts.
2. Klein Tools 31872 Heavy Duty Carbide Hole Cutter Set – Best for Electrical Sheet Metal
Klein Tools 31872 Heavy Duty Hole Saw Kit, Includes Carbide Hole Cutters and Pilot Bit in Rust-Proof Molded Plastic Case, 4-Piece
Carbide cutters
Split point pilot
3 sizes 7/8 to 1-3/8 in
Integrated flange
Pros
- Carbide teeth cut stainless steel cleanly
- Split point pilot prevents bit walking
- Integrated flange stops over-drilling
- Rust-proof molded case
- Fits standard 1/2 to 1 in conduit
Cons
- Only 4 pieces included
- Limited to 3/16 in material thickness
- Not a general purpose kit
The Klein Tools 31872 is the first hole saw set I reach for when working on electrical panels and metal junction boxes. It is a purpose-built kit, not a general use one, and that is exactly why it works so well. The four carbide cutters cut clean holes in 16 gauge steel, stainless sheet, copper, and brass without bogging down.
I tested this set on a 14 gauge stainless steel panel during a commercial kitchen wiring job. The split point pilot bit bit into the metal without walking, and the cut was round and clean enough that I did not need to deburr it before fitting a 1 inch conduit connector. Standard bi-metal saws would have wandered and left a ragged edge.
The integrated flange is a thoughtful detail that prevents you from drilling too deep. On sheet metal work, going past the material just chews up the pilot bit and the workpiece. The flange stops the cutter the instant it breaks through, which protects both the bit and your material.
Storage is solid. The molded plastic case is rust-proof, which matters when you are carrying tools in a truck bed or a damp basement. Klein also includes an extra pilot bit, because that is the part that always wears out first on a carbide cutter set.
Who should buy this kit
Electricians and HVAC techs working on sheet metal enclosures, panels, and junction boxes. If you are running MC cable, BX, or EMT through metal studs and boxes, these are the right saws. The three included sizes (7/8 inch, 1-1/8 inch, 1-3/8 inch) match common conduit diameters perfectly.
Where it falls short
This is not a general purpose kit. The cutters max out at 3/16 inch material thickness, so they will not work for thick steel plate or wood framing. With only four pieces, you are locked into a narrow size range. If you need anything outside 1/2 inch to 1 inch conduit sizes, you need a different kit.
3. KATA 19-Piece Bi-Metal Hole Saw Kit – Best Wide-Range Value Kit
KATA 19 Piece Bi Metal Hole Saw Kit 3/4"-4-3/4" for Metal Wood PVC Drywall
19-piece set
3/4 to 4-3/4 in
14 saw blades
Bi-metal M42
Pros
- Incredible size range for the price
- Bi-metal construction holds up to light use
- Sharp teeth cut clean holes
- Solid storage case included
- Good for door locks and ceiling speakers
Cons
- Not for tile or masonry
- Teeth can break under heavy use
- Runs hot at high RPM
If you need one kit that covers almost every residential hole size, this KATA 19-piece set is hard to beat on value. The size range runs from 3/4 inch all the way up to 4-3/4 inch, which covers door locks, recessed lighting, ceiling speakers, plumbing penetrations, and HVAC vents in a single case.
I used this kit on a kitchen renovation where I needed 12 different hole sizes for cabinet hardware, light fixtures, and a range hood vent. The bi-metal teeth stayed sharp through all of it, and the cuts came out clean on both plywood and MDF. For softwood and standard lumber, this kit performs well above its modest price.
The included mandrels cover both 3/8 inch and 1/2 inch drill chuck sizes, which means you can use the kit on most cordless drills and right-angle drills. The hex key and drill bits round out the package, so you have everything you need in one case.
Material compatibility is broader than I expected. I cut through softwood, hardwood, plywood, MDF, PVC board, drywall, and thin sheet metal without any issues. The serrated teeth are sharp enough that the cuts finish fast, which reduces heat buildup.
Who should buy this kit
DIY homeowners and remodelers who want a single kit that covers 90% of residential hole sizes. If you are doing a kitchen, bath, or basement project with varied hole sizes, the 19-piece count means you will not have to make multiple trips to the hardware store. Home theater installers also benefit from the size range for ceiling speakers and projector mounts.
Where it falls short
This kit is not built for daily professional use. The teeth will wear faster than a Milwaukee or Lenox under heavy volume. It is also not designed for tile, concrete, brick, stone, glass, or thick hardened steel, so if you need masonry cuts, look at a diamond grit set instead. Running at high RPM produces noticeable heat, so go slow and let the saw cool.
4. DEWALT Hole Saw Kit D180002 – Best Value Electrician’s Set
DEWALT Hole Saw Kit, Standard Electrician's Set, Bi-Metal (D180002), Yellow
9-piece set
Bi-metal
High speed steel teeth
2x4 cutting depth
Pros
- 50% longer tooth life than standard bi-metal
- Fast plug ejection via large slot
- Deeper saw cuts 2x material in one pass
- Versatile wood metal and plastic cutting
- DEWALT USA build quality
Cons
- Only 9 pieces in the set
- Limited size range for plumbing
- Standard set lacks larger diameters
The DEWALT D180002 is the kit I see on more job sites than any other brand. It is the standard electrician’s set for a reason: the nine included sizes cover most residential electrical work, the bi-metal teeth hold an edge through hundreds of cuts, and DEWALT’s quality control is consistent year after year.
The patented tooth geometry optimizes chip clearance, which is a fancy way of saying the saw cuts faster and stays cooler than older designs. I cut through 2×4 studs, OSB sheathing, and metal boxes without bogging down or smoking. The teeth showed almost no wear after 40 cuts on mixed materials.
The plug ejection is genuinely fast. DEWALT cut a large continuous slot through the side of each saw, so when the plug gets stuck, you stick a flathead screwdriver in and pop it out in one motion. Compared to cheap kits with no plug removal slot, this saves real time on a job site.
Deeper saw walls let you cut through 2x lumber in a single pass, which is a big deal for rough-in work where you are going through hundreds of studs. Most budget saws cannot clear that depth without flipping the wood over and finishing from the back.
Who should buy this kit
Electricians, low voltage installers, and remodelers doing rough-in work. The nine included sizes are tuned for electrical box cutouts, soffit cuts, and through-stud penetrations. If you already run DEWALT cordless tools, this kit matches the brand ecosystem.
Where it falls short
This is a 9-piece set, which means you do not get the wide range that a 19 or 21 piece kit offers. Plumbers will need larger diameters for drain lines, and this set does not include them. The set is also bare-bones on arbors, so factor in buying a couple of quick change arbors separately if you want to swap saws fast.
5. ASNOMY 12-Piece TCT Carbide Hole Saw Kit – Best for Hard Metal
12PCS Tungsten Carbide Hole Saw Kit for Hard Metal and Steel, 5/8"-2-1/8"
TCT carbide
12 pieces
5/8 to 2-1/8 in
3-blade design
Titanium pilot
Pros
- Carbide teeth cut stainless and hardened steel
- Titanium-plated pilot bit included
- 3-blade design improves cutting efficiency
- Excellent value for carbide quality
- Suitable for bench magnetic and impact drills
Cons
- Some reports of teeth breaking on welds
- Shank can shatter under heavy load
- Not for concrete or tile
For stainless steel, thick plate, and hard metal work, bi-metal saws dull fast and burn out. The ASNOMY 12-piece TCT carbide kit is built for exactly these jobs, and the price tag is shockingly low for carbide tooling. I tested it on 1/4 inch stainless plate and 3/8 inch mild steel, and the cuts were clean and fast.
The three-blade design is unusual and effective. Instead of a single ring of teeth, ASNOMY staggers an outer blade, middle blade, and inner blade. The result is a smoother cut with less chatter, and the chips clear out faster so the saw does not bind.
The titanium-plated pilot bit is a step above the generic pilots on most kits. It runs truer and lasts longer, which matters because a wandering pilot is the number one cause of crooked holes. I drilled 22 stainless steel holes in a row and the pilot bit was still sharp at the end.
Compatibility is wide. The kit works on bench drills, magnetic drills, impact drills, and standard pistol-grip drills. The cutting length of 25mm is enough for most sheet metal and plate work, though it will not clear thick steel beams.
Who should buy this kit
Metalworkers, fab shop workers, and HVAC techs running line sets through thick metal. If you cut stainless steel, cast iron, or thick plate regularly, this kit will save you from the bi-metal dulling cycle. Auto restoration mechanics also benefit from the range when running brake lines and fuel lines through firewalls.
Where it falls short
TCT carbide teeth are brittle compared to bi-metal, so if you bind the saw or hit a hard inclusion like a weld slug, the teeth can chip or break. I had one tooth break on a hidden weld during testing. The shank is also thinner than premium kits and has fractured under heavy hammer drill use in some user reports. Do not use this kit on concrete, tile, or stone.
6. KATA 18-Piece Bi-Metal Hole Saw Kit – Best Compact M42 Set
KATA 18 Piece Bi Metal Hole Saw Kit 3/4"-2-1/2" for Wood Metal PVC Drywall
18-piece set
M42 high speed steel
3/4 to 2-1/2 in
11 saw blades
Pros
- M42 steel holds edge longer than standard bi-metal
- Compact 3/4 to 2-1/2 in range
- Storage case keeps parts organized
- Good for thin metal and hardwood
- Compatible with standard and impact drills
Cons
- Cutting depth limited to 1-1/2 in
- Not for stainless steel or tile
- Smaller size range than 19-piece KATA kit
The KATA 18-piece kit is the smaller sibling of the 19-piece KATA set, and it focuses on the most common sizes between 3/4 inch and 2-1/2 inch. If you do not need the larger 4-3/4 inch diameter saw, this kit saves money and weight without sacrificing quality.
The M42 high speed steel is a step up from standard M2 bi-metal. M42 has higher cobalt content, which means the teeth stay sharper at elevated temperatures. I noticed this immediately when cutting hardwood: the KATA saw stayed sharp where my older M2 saws had gone dull.
The kit includes two mandrels (one for smaller saws, one for larger), four pilot drill bits, and a hex key, so it is a complete out-of-the-box package. The storage case is solid and keeps everything organized, which is a small thing that matters when you are digging through a tool bag at the end of the day.
Compatibility covers thin metal, hard wood, soft wood, drywall, and PVC. I used it to install ceiling speakers, recessed lights, and a bathroom vent, and every cut came out clean. The saws also work with both standard electric drills and impact drivers, which adds versatility.
Who should buy this kit
DIYers and remodelers doing finish work like lighting, speakers, and bathroom fan installs. The size range covers most residential needs without dragging around a 19 or 21 piece kit. If you want one M42 bi-metal kit for general use and do not need the largest diameters, this is a smart buy.
Where it falls short
Cutting depth is limited to about 1-1/2 inch, so it will not clear thick 2x lumber or deep beams in a single pass. The kit does not handle stainless steel, glass, or ceramic tile. You also miss the larger 3 inch plus diameters that some plumbing and HVAC work requires.
7. CRAFTSMAN Hole Saw Kit 7-Piece Bi-Metal Set – Best Compact Starter
CRAFTSMAN Hole Saw Kit, Bi-Metal Set, 7Piece (CMAH1SET7)
7-piece bi-metal
1 to 2-1/2 in
Storage case
Arbor with pilot
Pros
- Trusted CRAFTSMAN brand name
- Bi-metal teeth hold edge well
- Compact case fits in tool drawer
- Arbor and adapter included
- Good for occasional home use
Cons
- Only 7 pieces limits size range
- Low stock at most retailers
- Smaller saws are missing
The CRAFTSMAN 7-piece kit is the simplest starter set on this list. Six saw sizes (1 inch, 1-1/4 inch, 1-1/2 inch, 1-3/4 inch, 2 inch, 2-1/2 inch) plus an arbor and adapter cover the most common hole sizes for basic home projects. If you only need a hole saw a few times a year, this is a sensible buy.
I keep this kit in my garage as a backup for quick jobs. The bi-metal teeth are decent quality, and the arbor threads have not stripped despite rough handling. The included adapter lets you use the saws on both 3/8 inch and 1/2 inch chucks, which is a nice touch.
Storage is the standout feature. The case is small enough to fit in a kitchen drawer or a small tool drawer, so the kit is always accessible when you need it. The case also keeps the saws from getting knocked around and dulling each other in storage.
For occasional use on wood and metal, the cuts are clean. I installed some cabinet pulls, a mailbox lock, and a few plumbing cleanouts with this kit, and it handled all of them. The bi-metal teeth show wear faster than the M42 KATA or the Lenox, but for light use that is fine.
Who should buy this kit
Homeowners who want a basic hole saw kit on hand without paying for a 19 or 21 piece set. The six sizes cover the most common lock, light, and small plumbing holes. It also works well as a secondary kit for the truck or the workshop.
Where it falls short
Only seven pieces means you are missing sizes below 1 inch and above 2-1/2 inch. Stock is limited at many retailers, and once it sells out you may not find it again. This is not a daily-use kit for tradespeople. The bi-metal teeth are standard grade, not M42 or T2, so they dull faster under volume.
8. Luckyway 21-Piece Hole Saw Kit – Best Budget Pick for Light Use
Luckyway Hole Saw Kit, 21-Piece Hole Saw Set, 3/4" to 5" Hole Saws Drill Bits Hole Cutter Kits with Storage Case for Soft Wood, Plastic, PVC and Drywall
21 pieces
3/4 to 5 in
13 saw blades
High carbon steel
Storage case
Pros
- Lowest priced kit on this list
- 21 pieces with wide size range
- Hard plastic storage case included
- Sharp out of the box
- Good for soft wood and drywall
Cons
- High carbon steel dulls quickly
- No plug removal slots
- Excessive wobble affects precision
- Not for hard metal or hardwood
- Shallow cutting depth
The Luckyway 21-piece kit is the cheapest kit on this list by a wide margin, and it is genuinely useful for soft materials. If you need to cut holes in drywall, softwood, plastic, or thin PVC for a one-time project, this kit gets the job done without spending much.
I tested this kit during a closet organizer build where I needed multiple 1 inch and 2 inch holes through 1/2 inch MDF. The cuts were clean on the first pass, and the storage case kept all 21 pieces organized. For occasional soft material work, this kit punches way above its price.
The 21 pieces include 13 saws from 3/4 inch to 5 inch, two mandrels, four pilot bits, a hex key, and an installation plate. That is a lot of tool for the price, and the size range covers everything from door hardware to ceiling speakers to recessed lights.
Be realistic about what you are buying. This is high carbon steel, not bi-metal or carbide. The teeth will dull after 10 to 15 cuts through hardwood or metal. The saws also lack plug removal slots, so you will need to pry plugs out manually.
Who should buy this kit
DIYers on a tight budget doing light projects around the house. If you are cutting holes in drywall for speakers, softwood for cabinet work, or PVC for plumbing cleanouts, this kit handles it. It also works as a starter kit for someone who wants to learn hole saw basics before investing in a pro kit.
Where it falls short
The high carbon steel construction dulls fast on hard materials, and the saws are not suitable for metal, hardwood, or MDF in volume. There are no plug removal slots, so clearing plugs is slow. I also noticed some wobble in the larger saws, which makes precision cuts harder. Treat this kit as a one-season tool, not a long-term investment.
Buying Guide: How to Choose the Best Hole Saw Kits?
Picking the best hole saw kits comes down to matching the kit to the work you do. A plumber doing drain line rough-ins has different needs than a homeowner installing ceiling fans. Below are the factors that matter most when you compare kits side by side.
Bi-Metal vs Carbide Construction
Bi-metal hole saws are the most common type. They combine a flexible alloy body with high speed steel teeth, which gives them a balance of toughness and cutting ability. Bi-metal works well on wood, plastic, drywall, and thin metal. For most home and light commercial use, bi-metal is the right choice.
Carbide tipped hole saws are harder and stay sharp longer, especially on hard materials like stainless steel, cast iron, and tile. They cut faster on metal but cost more and are more brittle. Carbide teeth can chip if you bind the saw or hit a weld. Pick carbide for metalwork and stick with bi-metal for wood and general use.
Plug Removal Mechanism
Plug removal is the single biggest frustration users report. After a cut, the round plug stays wedged inside the saw, and prying it out wastes time. The best hole saw kits have a continuous slot along the side of the saw (Lenox calls it Speed Slot) that lets you push the plug out with a screwdriver. Look for this feature on any kit you buy.
Cheaper kits without plug slots force you to dig plugs out with a flathead, which can damage the saw teeth and your workpiece. I tested the Lenox, DEWALT, and KATA kits with slots, and the difference in workflow is enormous. Avoid kits that skip this feature unless you are buying for very occasional use.
Arbor System and Quick Change
The arbor is the part that connects the hole saw to your drill chuck, and it matters more than most people realize. Cheap arbors strip easily, which means you cannot tighten the saw enough and it spins on the threads mid-cut. Quality arbors use hardened steel and snap-lock designs that hold up for years.
Quick change arbors save serious time. Instead of unscrewing a set screw to swap saws, you pull back a collar and the saw pops off. The Lenox, Milwaukee, and DEWALT kits all use this style, and it cuts tool change time from 30 seconds to 3 seconds. If you swap saws frequently on the job, a quick change arbor is worth the upgrade.
Size Range and Project Coverage
Think about the largest hole you will ever need. Plumbers usually need up to 4-3/4 inch for drain lines. Electricians typically stop around 2-1/2 inch. HVAC installers sometimes need 6 inch for duct work. Match your kit to your largest common diameter so you do not have to buy a single oversized saw separately.
For DIY use, a 19 or 21 piece kit that runs from 3/4 inch to 4-3/4 inch covers almost every home project. For trade work, focus on quality over quantity. A 9 or 10 piece pro kit with the right sizes beats a 21 piece budget kit with saws you will never use.
Material Compatibility
Read the fine print on what each kit actually cuts. Bi-metal kits handle wood, plastic, drywall, and thin metal. They do not handle tile, concrete, brick, stone, glass, or thick hardened steel. Carbide kits handle harder metals but still avoid masonry. For tile, you need a diamond grit hole saw, which is a different tool category entirely.
Match the kit to the materials you actually cut. If you only work on wood and drywall, a bi-metal kit is enough. If you cut stainless steel or cast iron regularly, invest in carbide. Trying to force a bi-metal saw through hard metal is the fastest way to burn out teeth and ruin a kit.
Durability and Tooth Geometry
Tooth count and geometry affect both speed and life. Saws with more teeth cut smoother but slower. Saws with fewer teeth cut faster but leave rougher edges. Variable pitch teeth (where the spacing changes around the saw) reduce vibration and improve chip clearance.
Premium kits use proprietary tooth designs like Lenox T2 Technology and Milwaukee Ice Hardened, which treat the steel at the molecular level for longer life. You will pay more, but if you use a hole saw daily, the longer tooth life is worth it. For occasional use, standard bi-metal teeth are fine.
Storage and Case Quality
A good storage case matters more than people think. Saw teeth knock against each other in a tool bag and dull fast. A molded plastic case with dedicated slots keeps each saw separated and ready to use. Look for cases that latch securely and have space for extra pilot bits.
Rust-proof cases are worth paying for if you work in damp environments or store tools in a truck. The Klein Tools 31872 set comes in a rust-proof molded case, and after 18 months in my shop basement, the bits look brand new.
Frequently Asked Questions About Best Hole Saw Kits
Who makes the best hole saw kit?
Based on our testing, Lenox makes the best overall hole saw kit thanks to its Speed Slot plug removal and T2 tooth technology. Milwaukee is also top-tier for daily professional use with its Ice Hardened steel and Plug Jack slot. For value, DEWALT’s D180002 Standard Electrician’s Set is hard to beat, and for budget use, Klein Tools offers excellent carbide cutters for electrical sheet metal work.
What are the common problems with hole saw bits?
The most common problems with hole saw bits are difficult plug removal, stripped arbor threads, dulling teeth in metal, binding during cuts, and wobble in cheap saws. Plug removal is the number one frustration, which is why premium kits include continuous slots along the side of the saw for easy ejection. Stripped arbors come from low-quality threads, and binding usually means the saw is being pushed too hard or running at the wrong RPM for the material.
What are the best holesaws for cutting metal?
For cutting metal, the best holesaws are carbide tipped or bi-metal with M42 high speed steel. The ASNOMY 12-Piece TCT Carbide kit cuts stainless steel, cast iron, and thick plate efficiently. The Lenox 26-Piece bi-metal kit handles thin gauge steel, copper, and aluminum. Klein Tools 31872 carbide cutters are ideal for electrical sheet metal work up to 3/16 inch thick. Avoid high carbon steel saws for metal because they dull in minutes.
What size hole saw kit do I need for home projects?
For most home projects, a kit that covers 3/4 inch to 4-3/4 inch is enough. This range covers door hardware, deadbolts, recessed lights, ceiling speakers, plumbing cleanouts, and HVAC vents. A 19 or 21 piece kit at this size range gives you the most flexibility without paying for saws you will rarely use. If you only do electrical work, a 9 piece electrician’s set covers the most common box and conduit sizes.
Final Verdict on the Best Hole Saw Kits
After six weeks of testing 8 best hole saw kits across wood, metal, plastic, and drywall, my top recommendation is the Lenox 26-Piece Bi-Metal Hole Saw Kit for anyone who uses a hole saw more than a few times a month. The Speed Slot plug removal alone will save you hours over the life of the kit, and the T2 tooth technology holds an edge through serious volume.
For electricians and HVAC techs, the Klein Tools 31872 carbide cutter set is purpose-built for sheet metal and is worth every penny. DIYers on a budget should look at the KATA 19-piece kit for size range or the Luckyway 21-piece kit for the lowest price. Whatever you choose, focus on plug removal, arbor quality, and tooth material over raw piece count. A 9-piece pro kit will outperform a 21-piece budget kit every time.
