The Milwaukee M18 FUEL chainsaw 2727-21HD is worth it if you already own M18 tools and your cutting is yard-sized: storm cleanup, limbing and firewood rounds. It is a 16-inch cordless saw sold as a kit with a battery pack, rapid charger, 16 in. Oregon bar and chain, and a scrench [1]. For the next step, see Milwaukee M18 FUEL Compact Router: What It Handles and Its Limits.
Milwaukee rates it to cut hardwoods and claims up to 150 cuts per charge [2]. In practice, that means one battery can cover a typical afternoon of bucking fallen limbs, but a long day of cutting will outlast a single pack.
This review walks through what comes in the box, the features you will notice in daily use, how large a log it handles, and how it stacks up against a gas saw. You will also see its downsides and who should skip it.
What comes in the 2727-21HD kit
The 2727-21HD kit gives you everything you need to start cutting: the saw, a battery pack, a rapid charger, a 16-inch Oregon bar and chain, and a scrench. [1] If you already own M18 tools, the battery and charger also work across that lineup, so the kit adds to what you have.
The saw, battery and charger
The core of the kit is the M18 FUEL 16-inch chainsaw, a 12.0Ah battery and an M18 Rapid Charger. [1] That means you can unbox it, charge the pack and head out to the yard without buying anything else.
The 12.0Ah pack is one of the larger M18 batteries, which is why Milwaukee pairs it with this saw. A smaller pack from your drill will physically fit, but a big pack suits a tool that draws as much power as a chainsaw.
The 16-inch Oregon bar and chain
The bar and chain come from Oregon, a brand you’ll find on many saws and in most hardware stores. [1] When the chain wears out, you can shop for a matching 16-inch Oregon replacement instead of hunting for a proprietary part.
The 16-inch length is a common middle size for homeowner saws. It’s long enough for firewood rounds and fallen limbs without being awkward to handle around the house.
The scrench
A scrench is a combination screwdriver and wrench, and the kit includes one. [1] You use it to loosen the bar nuts, set chain tension and tighten everything back down. Keep it in your pocket or tool bag while you cut, since chains stretch as they warm up and you’ll want to adjust tension on the spot.
The 2727-21HDCH variant with a spare chain
Some retailers sell a version called the 2727-21HDCH, which adds an extra replacement chain to the kit. [3] A spare chain is handy if you cut a lot or don’t sharpen chains yourself: when one dulls, you swap in the fresh one and keep working, then sharpen or replace the dull chain later.
If you expect to tackle storm cleanup or a winter’s worth of firewood, the HDCH bundle saves you a separate trip for a chain. For occasional trimming, the standard 2727-21HD is enough.
Which features matter in daily use
The variable speed trigger and the dual-stud bar mount are the two features you’ll notice most on the 2727-21HD, because they decide how controlled your cuts feel and how well the bar stays put. The automatic oiler and the brushless motor work in the background, and they matter just as much over a season of yard work.
Variable speed trigger
The trigger is variable speed, so how far you squeeze it sets how fast the chain runs [4]. That gives you full control over the cut instead of an on-off switch that jumps straight to top speed [3].
In practice, this helps most at the start of a cut. Squeeze lightly to let the chain bite into the bark without skating across a round log, then squeeze fully once the kerf is started. It’s also handy when you’re trimming a small limb near a fence and want the saw to move slowly and predictably.
Dual-stud bar retention
The bar is held by two studs instead of one, which Milwaukee says improves bar and chain retention [4]. A bar that stays firmly clamped holds chain tension better, so you spend less time stopping to readjust.
You’ll appreciate this after a few cuts through knotty wood, when a loosely held bar can shift and let the chain sag. Two mounting points spread the clamping force, so the bar is less likely to creep.
Automatic oiler
The saw has an automatic oiler that feeds bar oil to the chain as it runs, so the chain stays properly lubricated [3]. You don’t have to pump oil by hand mid-cut.
Your job is to keep the reservoir filled with bar and chain oil. A dry chain heats up, dulls quickly and wears the bar, so topping off the oil each time you charge the battery is an easy habit to build.
Brushless FUEL motor
The 2727-21HD is part of the M18 FUEL line and uses a brushless motor [4]. A brushless motor has no carbon brushes rubbing inside it, so there are fewer parts to wear out and less energy lost as heat.
For you, that means more of each battery charge goes into turning the chain. The cluster’s article on the FUEL brushless label explains in plain terms what this means for runtime, power and tool life.
What size wood can it handle
The 2727-21HD handles the wood most homeowners actually cut: downed limbs, small trees and firewood rounds, including hardwoods. Milwaukee states the saw has the power to cut hardwoods [2]. That means oak, maple and hickory are fair game, not just soft pine. The bar is 16 inches long [5], so it suits logs and limbs comfortably narrower than that length.
Jobs it suits
This saw fits the cutting jobs that come up around a typical yard:
Storm cleanup, such as clearing a fallen branch off the driveway or cutting a toppled ornamental tree into movable pieces
Limbing, which means trimming the side branches off a downed trunk before you cut it up
Bucking firewood rounds, cutting a log into stove-length pieces of about 16 inches
Pruning back overgrown branches you can reach safely from the ground
For these jobs, the cordless setup is a real advantage. You can grab the saw, make a dozen cuts, and set it back down without warming up an engine.
When a bigger gas saw makes more sense
Large felling work is a job for a bigger saw. If you plan to drop mature trees with trunks much wider than the bar, a gas saw with a longer bar gives you more reach and the endurance to keep cutting. The same goes for processing several cords of firewood in one weekend. For that kind of work, a gas saw or a professional tree service is the safer, more practical choice.
Safety gear and kickback
Kickback is the main hazard with any chainsaw, cordless or gas. It happens when the upper tip of the bar touches wood or another object and the saw jerks back toward you. Keep the bar tip clear of logs and branches, hold the saw with both hands, and stand to the side of the cutting line.
Before you start, put on the right gear:
Chainsaw chaps or cutting pants to protect your legs
Safety glasses or a face shield for flying chips
Hearing protection, since a battery saw under load is still loud
Sturdy boots and work gloves for footing and grip
Cut only from stable footing, and never above shoulder height.
How does it compare with a gas chainsaw
Milwaukee pitches this saw as a direct replacement for a mid-size gas chainsaw. For most yard jobs, the bigger difference you’ll notice is that it’s simpler to run. The power claims come from Milwaukee itself, so treat them as a starting point rather than a guarantee for every log.
What Milwaukee claims about power
The saw is marketed as able to outperform a 40cc gas chainsaw while running on an 18V battery. [6] A 40cc engine is the size you find on many homeowner gas saws sold for trimming, storm cleanup and cutting firewood. That makes it a fair benchmark if you’re deciding between this kit and a typical gas model in the same class.
Milwaukee also says the saw cuts faster than gas. [2] In practice, cutting speed also depends on how sharp the chain is, the type of wood and how hard you press. A fresh chain in pine will feel very different from a dull chain in seasoned oak, whatever powers the saw.
Starting and fueling are much simpler
The biggest everyday difference is how you get the saw running. A two-stroke gas saw needs fuel and oil mixed at the right ratio, and you’ll usually pull the starter cord a few times, especially on a cold morning.
With the battery saw, you slide the pack in and pull the trigger. There’s no gas can to store in the garage and no old fuel going stale over the winter. You also skip the choke routine. That suits homeowners who use a chainsaw a few times a year, when a gas saw is most likely to give trouble after sitting.
Runtime is the trade-off
A gas saw keeps running as long as you have fuel to refill it, which takes about a minute. The battery saw stops when the pack runs down, and recharging takes much longer than refilling a tank.
That matters most on long jobs. Clearing a few downed limbs after a storm fits one charge comfortably. Spending a full Saturday bucking a fallen tree into firewood rounds is where gas keeps its edge, unless you plan your work around charging breaks.
What are the downsides
The biggest drawbacks are bulk, battery dependence and age: this is a long, front-heavy saw once the 12.0Ah pack is in, you will want a second battery for anything beyond a short job, and the design is several years old.
Size and weight with the big pack
The kit measures 36 inches long, 10 inches wide and 11 inches tall. [5] That is about the length of a yardstick, so plan on a shelf or wall hook rather than a spot in a standard toolbox. It also means you are swinging a sizable tool, not a compact pruning saw.
The 12.0Ah battery that comes with the kit adds noticeable heft to that frame. You feel it most when you hold the saw at arm’s length to trim limbs or cut above waist height. If most of your work is small branches, a lighter M18 pruning saw may be easier on your arms, and the sister article on the M18 FUEL Hatchet compares the two.
One way to manage the weight is to cut at waist level whenever you can. For example, drag storm branches to a sawhorse or a pile on the ground before you buck them into pieces.
Plan on a spare battery
A single pack goes flat partway through a heavy afternoon, such as bucking a downed tree into firewood rounds. When it does, you stop and wait for the charger. A second high-capacity M18 battery lets you swap and keep cutting while the first one recharges.
That spare is an extra purchase on top of the kit. If you already own large M18 packs from other tools, you may have this covered. If your current batteries are small 4.0Ah or 5.0Ah packs, expect shorter runs from them.
An older design
This saw has been on the market since at least November 2018, when it was reviewed against a 40cc gas saw. [6] Milwaukee’s lineup has grown since then, so before you buy, compare it with newer M18 FUEL chainsaws to see whether a later model better fits your bar length and weight preferences. An older model can still be a solid buy, especially if you find it discounted, but it is no longer the newest option in the range.

Who should buy it
Buy the 2727-21HD if you already run M18 tools and your saw work is yard-scale: storm limbs, fence-line cleanup, a few weekends of firewood rounds. Your existing M18 batteries and chargers work with it, so each extra pack you own adds cutting time without adding a second battery system to your garage.
If you cut all day, heat with wood, or clear acreage, a gas saw is still the better pick, because you refuel it in a minute instead of waiting on a charger. Before you order, compare the current kit price against the bare tool plus batteries you already own, since that math often decides it.
