Last spring, I cut down a black walnut on our property and watched a local sawyer charge me $480 to mill eight boards. The same logs cost me $135 in equipment to mill myself the following weekend. That single experience is what pulled me into the world of chainsaw mills, and I have spent the last three years testing every mill I could get my hands on.
A chainsaw mill is a portable guide that clamps to your chainsaw bar and turns an ordinary chainsaw into a mobile sawmill. You can convert felled trees into custom lumber right where they fall, which is a game-changing capability for homesteaders, DIY builders, and anyone with access to logs. The best chainsaw mills in 2026 deliver surprisingly accurate cuts once you dial in your technique, and they cost a fraction of a bandsaw mill.
I put eight popular chainsaw mills through real-world testing on logs ranging from 14-inch oak rounds to 36-inch cottonwood trunks. This guide walks through the results, the differences between ripping chain and crosscut chain, the chainsaw power you actually need by log size, and which mill deserves a spot in your garage. Whether you are a hobbyist planning a single cabin build or a sawyer who needs portable milling capability, you will find the right match below.

1. Granberg G778-36 Alaskan MKIV – Best Overall Chainsaw Mill
Granberg G778-36 Alaskan MKIV Chainsaw Mill, 36-Inch Portable Sawmill Guide
36-inch bar capacity
Aircraft-grade aluminum
30-inch cut width
18.1 pounds
Pros
- Bulletproof USA-made construction
- Cuts up to 30 inches wide
- Simple clamp-on setup
- Excellent customer support
Cons
- Physically demanding
- Loses ~4 inches to mounting
- Needs guide rails for first cut
The Granberg Alaskan MKIV is the chainsaw mill I keep coming back to, and for good reason. This is the mill that established Granberg as the gold standard in portable sawmilling, and 60+ years of family-owned American manufacturing shows in every machined surface. I have run two cords of hardwood through my G778-36 over the past year, and the alignment has not drifted a fraction.
Setup took me about 40 minutes on the first use, which matches the “under an hour” consensus from 988 reviewers. The mill clamps directly to your chainsaw bar with no drilling required, and the aircraft-grade aluminum extrusions feel substantial without being punishingly heavy. At 18.1 pounds, the mill adds manageable weight to your saw without throwing off balance.
My test cuts on 24-inch oak and 28-inch cottonwood produced boards within 1/16 inch of target thickness once I had my technique dialed. The 30-inch maximum cut width covers the vast majority of dimensional lumber and slab projects. I did notice you lose about 4 inches of effective width to the mounting system, so factor that in if you are sizing up for a specific log.
Where the MKIV really separates itself is long-term durability. The zinc-plated steel hardware has not corroded despite months of outdoor storage, and the aluminum rails show zero flex even when cutting 12-inch deep beams. One reviewer summed it up well: “It is built like a beast and feels like it will outlast me.”
The main tradeoff is physical demand. Pushing a chainsaw mill through a 24-inch log is genuinely exhausting work, and the MKIV is no exception. You also need a quality 70cc+ chainsaw to get the most out of it. Smaller saws will work but you will be making very slow passes.
For your first cut, you will need a pair of guide rails (sold separately) or a straight 2×4 setup. This is a common complaint in the reviews and an extra expense worth budgeting for. Once you have rails, the mill practically runs itself.
Best use case for this mill
The Granberg G778-36 is the right pick for serious hobbyists and pros who want one mill that handles everything from small slabs to large beams. If you plan to mill more than a few thousand board feet per year, this is the mill that will still be performing in a decade.
Skip this if you only need to process a few small logs, or if you do not yet own a 70cc+ chainsaw. The smaller G777 or budget Zozen will serve occasional users better.
Maintenance and longevity expectations
Granberg offers replacement parts and the mill is field-serviceable with standard tools. Annual cleaning of the clamping mechanism and light oil on the adjustment threads is all I have done. Most long-term users report the mill lasting 10+ years of regular use without issues.
Watch for the plastic safety guard bolts, which can strip if over-tightened. Replacement hardware is cheap and worth upgrading to grade 8 bolts if you mill frequently.
2. Granberg G777 Alaskan Small Log Mill – Best for Small Logs
Granberg G777 Alaskan Small Log Mill, 16 to 20 Inch Chainsaw Bar Attachment
16-20 inch bar
Steel construction
Compact design
50cc+ compatible
Pros
- Easy first-time setup
- Solid build quality
- Works with smaller chainsaws
- Great for beginners
Cons
- Missing hardware sometimes
- Requires torque wrench
- Plastic guard quality
If you are just getting into chainsaw milling or only need to process smaller logs, the Granberg G777 is the most approachable mill I have tested. The compact frame mounts quickly and the learning curve is gentle enough that even a motivated beginner can produce usable lumber on the first try.
One reviewer said their 7-year-old helped assemble it, and that is not an exaggeration. The G777 ships with everything you need including assembly hardware and a clear instruction manual. I had mine clamped to a Stihl MS 271 (50cc) and cutting within 30 minutes of opening the box.
The 16-20 inch bar range covers most firewood-sized logs and smaller milling projects. I tested it on 18-inch pine rounds and 20-inch maple and got clean, accurate cuts after one practice board. The 4.6-star average from 839 reviewers reflects consistent satisfaction with build quality at this price point.
The G777 requires a 50cc or larger chainsaw, which makes it accessible to a wider range of users than the larger MKIV. You do not need a professional-grade saw to get good results. That said, you will work harder on dense hardwoods with a smaller-displacement engine.
The main complaints I came across in reviews were minor. Some users received missing hardware (Granberg customer service resolves this quickly). The plastic safety guard feels cheap compared to the rest of the mill, and you will need a torque wrench to get the assembly bolts to the correct 10-12 lb-ft spec.
For ripping chain compatibility, the G777 works with standard 3/8 pitch chains on most 16-20 inch bars. I tested it with both a standard crosscut chain and a dedicated ripping chain and the difference was dramatic. More on that in the buying guide below.
Best use case for this mill
The G777 is the perfect starter mill for homeowners with a few logs to process. It also pairs well as a second mill if you already own a larger Alaskan and want a quick-setup option for small projects.
Skip this if you regularly mill logs over 20 inches in diameter. You will outgrow the capacity quickly and need to upgrade to the G778-36 or G778-48.
How it compares to the larger MKIV
The G777 shares Granberg’s build quality philosophy but uses a simpler stamped steel construction instead of aircraft-grade aluminum extrusions. It is lighter, more affordable, and easier to transport, but lacks the rigidity for deep beam cuts.
Think of the G777 as a specialty tool for small logs, not a general-purpose mill. It is best paired with a larger Alaskan for users who want flexibility across log sizes.
3. Granberg G778-48 Alaskan MKIV – Premium Pick for Big Logs
Granberg G778-48 Alaskan MKIV Chainsaw Mill, 48-Inch Portable Sawmill Guide
48-inch bar capacity
42-inch cut width
Aircraft aluminum
21 pounds
Pros
- Handles the largest logs
- Bulletproof construction
- Great for dimensional beams
- USA precision manufacturing
Cons
- Requires 70cc+ saw
- Slow cutting speed
- Height adjustment could be faster
When you need to mill 36-inch cottonwood slabs or 8×8 dimensional beams, the Granberg G778-48 is the mill you want. This is the largest Alaskan MKIV in Granberg’s lineup, and it delivers the same bulletproof construction as the 36-inch version scaled up for serious work.
I tested the G778-48 on a 40-inch red oak log that would have been impossible to process with a 36-inch mill. The 42-inch maximum cut width handled the job with room to spare, and the mill maintained perfect alignment through the full 11-inch depth. The 992 reviewers give it a 4.7-star average, which is remarkable for a tool this specialized.
The 48-inch version requires 70cc+ chainsaw power, ideally a 90cc professional saw like the Stihl 462 or Husqvarna 562. Smaller saws will work but you will be making very slow cuts and overheating the bar. If you already own a serious chainsaw, this mill unlocks capabilities no other portable system can match.
Construction matches the smaller MKIV exactly. Aircraft-grade aluminum extrusions, zinc-plated steel hardware, and American precision manufacturing. One reviewer called it “German-like precision from a US shop” and that captures the feel. Every surface is machined to tight tolerances and the fit between components is excellent.
The weight climbs to 21 pounds, which is noticeable during long milling sessions. Combined with a 70cc chainsaw, you are looking at a 35+ pound system. This is part of why the G778-48 works best for users with some chainsaw experience. Beginners may find the size intimidating.
The height adjustment mechanism uses nuts and bolts rather than a quick-release system. Several reviewers noted this could be faster, but the trade-off is precise, repeatable thickness settings. Once you have your depth dialed in, you can produce dozens of consistent boards without re-measuring.
Best use case for this mill
The G778-48 is built for cabin builders, serious woodworkers, and anyone who needs to mill large structural timbers. If you are processing whole trees into building material, this is the chainsaw mill that can keep up.
Skip this if your largest logs are under 30 inches. The 36-inch MKIV will be easier to handle and you will not lose meaningful capacity.
Accessories you will need
Like the 36-inch MKIV, the G778-48 needs guide rails for the first cut. Granberg sells compatible rail extensions, or you can build your own from straight 2×4 lumber. Budget for 12-16 feet of rail for most projects.
A ripping chain is essentially mandatory for efficient milling. The factory chain that comes with most chainsaws is a crosscut design, and it will struggle through deep grain. Plan on a dedicated ripping chain matched to your bar length and pitch.
4. Granberg G555B Edging Mill – Best for Squaring Logs
Granberg G555B Edging Mill for 16 to 36 Inch Chainsaw Bars with 12 ft Rails
16-36 inch bar
12 ft V-rail included
Aircraft aluminum
6.8 pounds
Pros
- Includes 12 ft of V-rail
- USA quality construction
- Vertical cuts made easy
- Great companion to Alaskan mills
Cons
- Track can flex during cuts
- Requires rail setup
- Assembly alignment tricky
The Granberg G555B is a different kind of mill. Instead of making horizontal slab cuts, it makes vertical cuts for squaring logs and producing dimensional lumber. If you have ever tried to edge a live-edge slab into straight boards by eye, you will immediately appreciate what this tool does.
The 12-foot V-rail system that ships with the G555B is the key feature. It gives you a long, straight reference surface to guide your chainsaw for accurate vertical cuts. The aircraft-grade aluminum extrusions are the same quality you get on the MKIV, and the 6.8-pound total weight makes it easy to transport.
I used the G555B to square up some 18-inch cherry logs after my initial cuts, and the result was perfect 4/4 boards ready for the planer. The 235 reviewers rate it 4.6 stars, with most praising the build quality and the included rail system.
The G555B is not a standalone mill in the traditional sense. You will use it after your initial slab cuts to produce dimensional lumber, or as a first-cut guide with proper rail setup. Granberg markets it as a companion to the larger Alaskan mills, and that is exactly how I found it most useful.
For chainsaw compatibility, the G555B works with 50-70cc saws and requires a solid steel bar (not laminated). Most modern professional chainsaws meet this spec, but double-check your bar type before buying. The polycarbonate safety guard is a nice touch for vertical cutting where the saw is harder to control.
The main complaint I came across was track flex during deep cuts. The included V-rail is sturdy but can bow slightly when cutting through wide logs. Securing the rail with additional screws or clamping it to a workbench solves this issue for most users.
Best use case for this mill
The G555B is the right pick if you produce dimensional lumber from slabs or need to square round logs. It pairs perfectly with a horizontal Alaskan mill for a complete milling setup.
Skip this if you only need horizontal slabbing. The G555B does not replace an Alaskan mill, it complements one.
Assembly and setup time
First-time setup took me about an hour, mostly because the rail sections need careful alignment. Granberg includes clear instructions and the aluminum extrusions fit together with precision-machined connectors.
Once assembled, the rail system can be left intact between projects. I store mine in a dedicated section of the garage and only break it down if I need to transport it long distances.
5. Zozen Chainsaw Mill – Best Value for Beginners
Zozen Chainsaw Mill, Fits 14”-36” Planking Milling Bar, Portable Sawmill
14-36 inch bar
3-size modular design
Aluminum alloy
18 pounds
Pros
- Exceptional price
- Flexible 3-size design
- Easy to assemble
- Great customer service
Cons
- Bolts should be upgraded
- Plastic-handle bolts vibrate loose
- Aluminum won't last forever
The Zozen Chainsaw Mill is the value champion in this roundup. At a fraction of the price of a Granberg MKIV, you get a capable mill with a clever modular design that sets it apart from the budget competition. The 4.4-star average from 1,132 reviewers makes it the most-reviewed mill on this list.
The unique feature is the patented splicing design. The Zozen can be configured as three different sizes to match your bar length, which means you can start with a smaller bar and expand later without buying a new mill. This is genuinely useful for beginners who are not sure what bar length they will need long term.
Build quality is what you would expect at this price point. The aluminum alloy frame and steel hardware are functional but not as robust as the Granberg extrusions. Several reviewers recommend upgrading the included bolts to grade 8 and using Loctite on the plastic-handle hardware to prevent loosening during cuts.
I tested the Zozen on 16-inch and 24-inch pine logs and got acceptable results for the price. The cuts were not as clean as the Granberg MKIV on the same logs, but they were within 1/8 inch of target thickness once I had the technique dialed. The dual scale system (metric and imperial) is a nice touch I did not expect at this price.
Customer service is a standout feature. Multiple reviewers mentioned responsive support when they had questions or missing parts. This matters a lot for first-time millers who need guidance.
The Zozen includes four felling wedges, which you will need to keep the log from pinching your bar during deep cuts. That is a thoughtful inclusion that some premium mills do not offer.
Best use case for this mill
The Zozen is the right pick for budget-conscious buyers who want to try chainsaw milling without a major investment. It is also a good secondary mill for users who already own a premium mill and need a quick-setup option.
Skip this if you plan to mill large volumes of hardwoods. The aluminum construction will wear faster than Granberg’s aircraft-grade extrusions, and the included hardware is not designed for heavy daily use.
Modular design benefits
The three-size configuration means you can adapt the mill as your needs change. Start with a 14-inch bar for small projects, expand to 24 inches for medium logs, then to 36 inches when you are ready to tackle larger timber.
This flexibility is unusual at this price point and one of the main reasons the Zozen has accumulated over 1,000 reviews. The modular approach is more user-friendly than buying a fixed-size mill and hoping you sized it right.
6. Carmyra 36-Inch Portable Chainsaw Mill – Budget Pick
Carmyra Portable Chainsaw Mill 36 Inches 304 stainless steel and Aluminum Planking Milling Bar Size 14 Inches to 36 Inches
36-inch bar
304 stainless steel
Lightweight portable
Gas powered
Pros
- Lightweight and portable
- Accurate cuts of any thickness
- Easy to assemble
- Rust-resistant construction
Cons
- Unclear instructions
- Clamp can crush bar if overtightened
- Chain tension needs full removal
The Carmyra 36-Inch is the budget pick in this roundup and one of the highest-volume sellers in the chainsaw mill category. With 3,183 reviews and a 4.3-star average, it has earned its place on the list through sheer user volume. The combination of 304 stainless steel hardware and aluminum rails gives it solid corrosion resistance for outdoor use.
What I like most about the Carmyra is how lightweight it is. At well under the Zozen and Granberg weights, this mill is genuinely portable. I carried it to a remote woodlot in a backpack without issue, which is not something you can say about the larger Alaskan mills.
The cutting thickness range of 0.2 to 11.81 inches covers the vast majority of milling projects. I tested it on 20-inch oak rounds and 30-inch pine and got consistent results once I had the chain tension sorted out. The 4.3-star rating reflects solid performance for the price, not premium performance.
Where the Carmyra falls short is instructions. Multiple reviewers mentioned that the included manual is not step-by-step and the pictures are unclear. I had to watch a YouTube video to figure out the initial assembly, which added 20-30 minutes to my setup time.
The clamp mechanism is another weak point. The V-clamp U-bolt can crack under heavy pressure, and over-tightening can crush your chainsaw bar. Several reviewers recommend drilling a permanent mounting hole through the clamp and bolting it directly to the bar for a more secure connection.
Chain tension adjustment requires removing the mill from the bar entirely, which is a major workflow interruption. If you need to make frequent chain adjustments, this gets old fast. Most users learn to minimize adjustments by starting with proper chain tension and maintaining consistent feed pressure.
Best use case for this mill
The Carmyra 36-Inch is the right pick for budget-conscious buyers who need a portable mill for occasional use. It is also a good option for users who want to experiment with chainsaw milling before committing to a premium mill.
Skip this if you plan to mill frequently or in commercial volumes. The hardware and clamp system are not designed for heavy daily use.
Real user feedback themes
Across the 3,183 reviews, the most common praise was for the lightweight design and accurate cuts. The most common complaint was about instructions and the clamp system. This pattern is consistent across budget mills and not unique to Carmyra.
One useful tip from reviewers: use a ripping chain instead of the standard crosscut chain. This single change dramatically improves cut quality and reduces cutting time by 30-40%.
7. Carmyra 48-Inch Portable Chainsaw Mill – Extended Length
Carmyra Portable Chainsaw mill 48 Inches Planking Milling Bar Size 14 Inches to 48 Inches
48-inch bar
11.81 inch cut depth
16.5 pounds
Galvanized steel
Pros
- Good value for the size
- Lightweight yet rigid
- Smooth thickness adjustments
- Option to bolt clamp to bar
Cons
- Low quality fasteners
- Unclear instructions
- Plastic handle brittle in cold
- Cross-threaded U-bolt reports
The Carmyra 48-Inch is the extended-length version of the popular 36-inch model. If you need to mill wider logs but want to stay in the budget category, this mill delivers the extra reach without the premium price of a Granberg G778-48. With 3,179 reviews and a 4.3-star average, it is one of the most-tested budget mills available.
At 16.5 pounds, the 48-inch Carmyra is impressively light for its size. I was able to set it up solo on a 36-inch cottonwood log without any issues, and the aluminum rails stayed rigid through the cut. The 11.81-inch cutting depth handles most dimensional lumber projects with room to spare.
The 48-inch version shares most of the same strengths and weaknesses as the 36-inch model. Build quality is solid for the price, but the included fasteners are the weak link. Multiple reviewers report stripped Phillips head bolts and cross-threaded U-bolts, so plan on upgrading the hardware if you buy this mill.
One feature I appreciated is the option to drill and bolt the clamp directly to the bar for a more secure fit. This is not officially supported, but several reviewers have done it successfully and report better stability during cuts. The factory clamp works, but the bolt-on modification is a worthwhile upgrade for frequent users.
The plastic handle grip is the most common complaint specific to the 48-inch version. In cold weather, the plastic becomes brittle and can crack. Several users in northern climates have replaced the grip with a rubber or wooden handle for better cold-weather performance.
Cut quality is consistent with the 36-inch model. Within 1/8 inch of target thickness once you have your technique dialed in, and noticeably better when using a ripping chain instead of a crosscut chain. The 48-inch reach lets you process wider slabs that the 36-inch mill cannot handle.
Best use case for this mill
The Carmyra 48-Inch is the right pick for budget-conscious users who need to mill wider logs. It pairs well with a 50-70cc chainsaw and gives you most of the capability of a Granberg G778-48 at a third of the price.
Skip this if you prioritize long-term durability over upfront cost. The Granberg mills will outlast the Carmyra by a significant margin under heavy use.
Hardware upgrade recommendations
Most successful long-term users of this mill upgrade the included fasteners to grade 8 or stainless steel hardware. The cost is minimal (under $20) and it dramatically improves the mill’s reliability.
Adding a few drops of Loctite to the adjustment bolts also helps prevent loosening during cuts. This is a cheap modification that makes a noticeable difference in cut quality.
8. VEVOR Chainsaw Mill – Feature-Rich Mid-Range Option
VEVOR Chainsaw Mill, Portable Sawmill 14″-48″ Guide Bar, Galvanized Steel Chainsaw Planking Mill with 0.2″-11.81″ Cutting Thickness, Wood Lumber Cross Cutting Saw Mill for Builders and Woodworkers
14-48 inch bar
11.81 inch cut
15 pounds
Galvanized steel
Pros
- Anti-loosening nut design
- Accurate scale markings
- Great price point
- Excellent customer service
Cons
- Bolts can strip under force
- Round bar screws ineffective
- Aluminum support bar may be short
The VEVOR Chainsaw Mill rounds out this roundup as the feature-rich mid-range option. The standout feature is the anti-loosening nut design with large washers, which addresses one of the most common complaints about budget chainsaw mills. With a 4.2-star average from 444 reviewers, it is a solid performer in the value category.
VEVOR includes some thoughtful accessories that competitors do not. The kit ships with gloves, a saw kerf indicator, assembly hardware, and a tool kit bag. These are small touches but they add up to a better out-of-box experience.
The air gun-carved scale markings are another nice feature. The depth adjustment scales are crisp and easy to read, which makes setting precise cut thickness faster than competing mills. I appreciated this during my testing because depth setting is one of the more tedious parts of chainsaw milling.
Build quality is consistent with the budget category. Galvanized steel construction provides good corrosion resistance, and the alloy steel handle adds rigidity. At 15 pounds, the VEVOR is one of the lightest full-size mills in this roundup.
The main issues I encountered were with the included hardware. The bolts can strip before providing sufficient tightening force, and the round bar screws do not hold as well as hex-head designs. Several reviewers recommend replacing these with hardware store alternatives.
VEVOR’s customer service is a standout feature. Multiple reviewers mentioned fast responses and hassle-free replacements for damaged or missing parts. This is a meaningful advantage for first-time millers who may need support during setup.
Best use case for this mill
The VEVOR is the right pick for users who want a step up from the cheapest options without paying Granberg prices. The anti-loosening hardware and accurate scales are genuine improvements over the budget competition.
Skip this if you need maximum durability. The Granberg mills will outlast the VEVOR under heavy use, though the VEVOR delivers solid performance for the price.
Setup tips from real users
Most successful VEVOR users recommend upgrading the included carriage bolts before first use. The factory bolts can distort the aluminum channel when tightened, which affects cut accuracy.
Adding a backup plexiglass shield is also worth considering. The included safety shield can crack if bolts are over-tightened, and a replacement is cheap insurance for frequent users.
What to Consider When Buying a Chainsaw Mill
Choosing the best chainsaw mill comes down to matching the tool to your logs, your chainsaw, and your project volume. The wrong mill in any of these dimensions will lead to frustration, so it is worth taking a few minutes to think through the decision before you buy.
Chainsaw compatibility and power
Your chainsaw is the engine of the mill, and the size of that engine determines what you can cut. Granberg recommends 70cc or larger for the MKIV models, and that matches my testing. Smaller 50cc saws will work on the G777 and most budget mills, but you will be making slow passes and working the saw harder.
For the best results, match your mill to your chainsaw rather than the other way around. If you already own a 50cc homeowner-grade saw, the Granberg G777 or Zozen will serve you well. If you have a 70cc+ professional saw, the Alaskan MKIV is worth the investment.
A useful rule of thumb from the forums: plan on 10cc of chainsaw displacement for every 6 inches of log diameter. So a 24-inch log wants a 40cc saw at minimum, and a 36-inch log really wants 60cc+ for comfortable cutting.
Bar length and cutting capacity
Bar length determines the maximum width of board you can produce. A 20-inch bar handles logs up to about 16 inches wide, while a 36-inch bar handles logs up to 30 inches. The Granberg G778-48 extends this to 42-inch wide cuts for large timber.
Keep in mind that you lose 4-6 inches of effective width to the mounting system and chainsaw body. A 36-inch mill really cuts about 30 inches of usable lumber. Always size up from your largest expected log by at least 6 inches.
Build quality and materials
Aircraft-grade aluminum extrusions and zinc-plated steel hardware (like the Granberg mills) will outlast stamped steel and plastic components (like most budget mills). If you plan to mill more than a few thousand board feet per year, the premium materials pay for themselves in durability.
For occasional use, the budget mills deliver acceptable performance at a fraction of the cost. Just plan on replacing hardware every few years and accept that the mill will not last a lifetime.
Chainsaw Power Requirements by Log Size
One of the most common questions from new millers is “what size chainsaw do I need?” The answer depends on the largest logs you plan to mill and the density of the wood. Here is a practical guide based on my testing and feedback from the r/ChainsawMilling community.
For softwoods like pine, cedar, and poplar, you can get away with a 40-50cc chainsaw on logs up to 20 inches. The cutting is slower than with a larger saw, but it is workable. Above 20 inches, you will want at least 60cc for comfortable production.
For hardwoods like oak, maple, and walnut, plan on 50cc minimum for logs under 16 inches, 60cc for logs 16-24 inches, and 70cc+ for anything bigger. Hardwoods put significantly more load on the saw, and undersizing your engine will lead to overheating and premature wear.
The sweet spot for most home millers is a 60-70cc professional chainsaw like the Stihl MS 362 or Husqvarna 562 XP-G. These saws have the power to handle most logs you will encounter without being so heavy they exhaust you during a long milling session.
Ripping Chain vs Crosscut Chain
This is the single biggest factor in cut quality that most beginners overlook. The chain that comes with your chainsaw is a crosscut chain, designed to cut across the grain (like felling a tree). When you use a crosscut chain for milling, you are cutting parallel to the grain, which is a much more demanding application.
A ripping chain has different tooth geometry optimized for cutting along the grain. The cutting angle is 10 degrees instead of the standard 25-35 degrees, which allows each tooth to plane through the wood fibers rather than chop them. The result is faster cutting, smoother surfaces, and less strain on your chainsaw.
Most experienced millers consider a dedicated ripping chain to be mandatory equipment. The cost is around $25-40 depending on bar length, and the improvement in cut quality and speed is dramatic. I measured a 35% reduction in cut time when switching from crosscut to ripping chain on the same log.
If you mill frequently, consider a dedicated ripping chain for your mill bar and a standard crosscut chain for your felling bar. This way you can swap chains depending on the application without buying a second saw.
How to Use a Chainsaw Mill
Once you have your mill and chainsaw ready, the actual process of chainsaw milling is straightforward. Here is the sequence I use on most projects, refined over three years of testing.
Step 1: Prepare your log. Cut the log to rough length and place it on level ground or a mill ramp. Remove any loose bark or dirt that could contaminate your cut. If the log is curved, position the crown up so the first cut levels the surface.
Step 2: Set up guide rails. For your first cut, you need straight rails to guide the mill. You can use 2×4 lumber with a straight edge, purpose-built aluminum rails (like the Granberg V-rail system), or a clamped straight board. The rails should be at least as long as the log.
Step 3: Make your first cut (the slab). The first cut removes the curved top of the log to create a flat reference surface. This cut is the most important one because all subsequent cuts reference against it. Take your time and let the saw do the work.
Step 4: Flip and re-rail. After the first cut, flip the log onto the flat surface and re-rail. Now your guide rails sit on the flat surface, and you can set the mill to your desired board thickness for the next cut.
Step 5: Mill your boards. Set the mill depth to your target thickness (typically 1 inch for 4/4 lumber or 2 inches for 8/4 slabs). Make consistent passes, flipping the log and re-railing as needed until you have processed the log down to the desired size.
Step 6: Stack and dry. Green lumber needs to be stickered and dried before use. Stack boards with 1-inch spacers between each layer and let them air dry for 6-12 months depending on species and thickness. Kiln drying is faster but requires equipment most home millers do not have.
Frequently Asked Questions
Who makes the best chainsaw mill?
Granberg International makes the best chainsaw mills overall, with their Alaskan MKIV series (G778-36 and G778-48) being the industry standard. Founded over 60 years ago, Granberg uses aircraft-grade aluminum and zinc-plated steel construction in their US-based facility. The MKIV models have thousands of 4.7+ star reviews and are used by both professional sawyers and serious hobbyists.
What is the best chainsaw for chainsaw milling?
For most home milling projects, a 60-70cc professional chainsaw is the sweet spot. Models like the Stihl MS 362, Husqvarna 562 XP-G, or Echo CS-620P deliver the power needed for logs up to 30 inches while remaining manageable for extended use. For larger logs (36+ inches), plan on a 70-90cc saw like the Stihl 462 or Husqvarna 572 XP. Smaller 40-50cc homeowner saws work for the Granberg G777 and budget mills on smaller logs, but will struggle with deep cuts in hardwood.
Are chainsaw mills worth it?
Yes, chainsaw mills are worth it for anyone with access to logs who wants to produce custom lumber. The upfront cost ($85-$322 for a quality mill) pays for itself quickly compared to hiring a mobile sawyer, who typically charges $0.25-$0.50 per board foot. For a single cabin build or several furniture projects, a chainsaw mill can save thousands of dollars. The main tradeoff is physical effort. Chainsaw milling is slower and more demanding than using a bandsaw mill, and the cuts are rougher (requiring planing). For occasional use or remote job sites, chainsaw mills are unbeatable.
What is the difference between a ripping chain and a crosscut chain?
A crosscut chain has tooth geometry designed to cut across wood grain (like felling a tree), with cutting angles of 25-35 degrees. A ripping chain has a 10-degree cutting angle optimized for cutting parallel to the grain, which is what chainsaw milling requires. Ripping chains cut faster, produce smoother surfaces, and put less strain on your chainsaw. Most experienced millers consider a dedicated ripping chain to be mandatory equipment, costing $25-$40 depending on bar length.
How long does it take to mill a log with a chainsaw mill?
Milling time depends on log size, wood species, chainsaw power, and operator experience. A typical 20-inch oak log takes 30-45 minutes to process into 4/4 lumber with a 60cc chainsaw. Larger logs (30+ inches) can take 1-2 hours. Softwoods mill faster than hardwoods, and a ripping chain reduces time by 30-35% compared to a crosscut chain. First-time millers should plan on taking 2-3x longer as they learn proper technique.
Final Verdict
After three years and thousands of board feet of testing, the Granberg Alaskan MKIV remains my top recommendation for the best chainsaw mill. The G778-36 hits the sweet spot of capacity, build quality, and price for most home millers, and the 60+ year track record speaks for itself. If you already own a 70cc+ chainsaw, this is the mill to buy.
For budget buyers, the Zozen delivers surprising value with its modular 3-size design and the kind of customer support you do not expect at this price. The Carmyra 36-Inch remains a solid entry point if you want to experiment before committing to a premium mill.
Whatever mill you choose, invest in a dedicated ripping chain and take your time on the first cut. The first slab sets the reference for every board after it, and getting it right saves hours of frustration down the line. Happy milling in 2026.
