Pros & Cons
- No gas, no pull-cord -- instant start every time, which matters most when you are cold, wet, and dealing with storm cleanup.
- Automatic chain oiler with window gauge -- the visible oil level window lets you monitor lubrication at a glance without removing the bar cover.
- Tool-free chain tensioning -- adjusting chain tension takes seconds with the built-in knob, even with gloves on.
- Low vibration compared to gas saws -- the brushless motor produces dramatically less vibration for extended limbing and bucking sessions.
- Shares batteries with the entire M18 ecosystem -- if you already run Milwaukee drills and saws on M18, the 2727-20 fits right into your existing battery rotation.
- Electric brake stops chain immediately on trigger release -- significantly reduces the risk of contact injuries during repositioning and carrying.
- Battery life limits extended felling sessions -- a single 8.0Ah battery handles about 45-60 minutes of active cutting before needing a swap.
- Less power than pro-grade gas saws -- sustained felling of hardwood trees over 12 inches in diameter will push the motor harder than it was designed for.
- Heavy with battery attached -- the 12.5-lb bare weight climbs past 15 lbs with a 12.0Ah HIGH OUTPUT battery, making overhead limbing work tiring.
- Oil cap threading is sensitive -- over-tightening the bar oil cap can strip the threads on the reservoir, a recurring complaint among users.
- Chain is not Oregon standard -- replacement chains are available but require matching the specific pitch and gauge, limiting off-the-shelf buying options.
🔋 Battery Compatibility
Use M18 HIGH OUTPUT 8.0Ah or 12.0Ah. A 5.0Ah will work but limits cutting time significantly.
🎯 Best For
The Milwaukee 2727-20 is the ideal chainsaw for homeowners with wooded properties who deal with occasional storm cleanup, seasonal firewood processing, and regular limb removal but want to stay completely free of gasoline and carburetors. It is equally well-suited for tree care professionals who work in HOA communities or indoor tree removal situations where gas fumes are genuinely problematic. If you are clearing a fence line, processing a downed tree into firewood rounds, or maintaining hiking trails on your property, this saw handles the work without the pull-cord frustration or ethanol-related storage headaches of gas alternatives. The M18 battery compatibility makes it especially attractive for Milwaukee tradespeople who already carry M18 batteries on every job -- no additional charging infrastructure required.
How We Tested
I ran the Milwaukee 2727-20 through a full day of outdoor cutting on recently felled oak and pine logs ranging from 6 inches to 14 inches in diameter. Testing started with a full M18 HIGH OUTPUT 12.0Ah battery. I counted cuts through 8-inch pine rounds until the battery depleted, then repeated the test with an 8.0Ah HIGH OUTPUT and a 5.0Ah standard pack. I timed the automatic oiler by checking chain and bar oil consumption every 20 cuts and comparing it to manual oiling intervals on a comparable gas saw. Vibration was evaluated by wearing a vibration meter strapped to my right wrist during 15 minutes of continuous limbing. I also tested the tool-free tensioning system by deliberately running the chain loose and re-tensioning it cold, with gloves, to simulate real field conditions.
Performance Deep Dive
Cutting Speed and Power
Through clean, dry pine at 8 inches diameter, the 2727-20 cuts at a pace that will surprise anyone who has used lower-voltage battery chainsaws. The POWERSTATE brushless motor maintains chain speed under load well, and I did not experience the dramatic bogging that plagues some 18V chainsaws in dense hardwood. Through green oak at 10 inches diameter, the motor works harder and chain speed drops noticeably on the deepest part of the cut -- manageable but clearly approaching the tool's limits. For logs under 12 inches in diameter, the 2727-20 is genuinely competitive with homeowner-grade gas chainsaws in cutting time.
Automatic Oiler and Chain Life
The automatic oiler with adjustable flow is a standout feature. Running the flow at the mid setting through 40 cuts in dry pine, the bar and chain maintained good lubrication with no visible heat discoloration on the bar rail. The translucent oil reservoir window is positioned where you can actually see it without removing any covers -- a small detail that matters when you are monitoring the saw between cuts. Chain sharpness held well through the first 90 minutes of pine cutting, which aligns with Milwaukee's guidance of 2-3 hours in clean wood before touching up with a file.
Vibration and Ergonomics
Measured vibration at the handle during limbing averaged roughly 4.5 m/s2 -- substantially lower than a typical 40cc gas chainsaw at comparable throttle. Over a full morning of tree work, my right hand and forearm showed noticeably less fatigue than I typically experience with gas equipment. The variable speed trigger also helps; pulling it halfway through thin limbs under 3 inches uses less current and generates less vibration than full-throttle cutting, extending both comfort and battery life.
❓ Frequently Asked Questions
Can it fell a tree?
Yes -- trees up to about 14″ diameter. For larger trees, you’ll need a more powerful gas chainsaw.
How long does the chain stay sharp?
With clean wood, expect 2-3 hours of cutting before sharpening. Dirty or nail-embedded wood dulls faster.
What chain oil does it use?
Standard bar and chain oil. The automatic oiler has an adjustable flow rate and a visible oil level window.
How does it compare to the DeWalt DCCS670B?
The DeWalt runs on 60V FLEXVOLT and delivers slightly more sustained power through large hardwood logs. The Milwaukee runs on 18V and is better for M18 ecosystem users. Both cut similarly through typical homeowner work under 12 inches diameter.
Does it have a chain brake?
Yes -- a front hand guard chain brake activates on kickback, stopping the chain rapidly to reduce injury risk.
Comparable Alternatives
DeWalt DCCS670B (60V FLEXVOLT) -- The DeWalt runs on 60V rather than 18V, which translates to more sustained power through large logs. It weighs slightly less at 12.2 lbs bare and costs roughly $30 less. If you are not invested in the Milwaukee M18 ecosystem, the DCCS670B is a strong competitor. However, M18 users will find better battery sharing value with the 2727-20.
EGO CS1600 (56V) -- EGO's 16-inch chainsaw uses a 56V battery that delivers gas-comparable power and comes with a battery and charger in most kit configurations. It is an excellent option for homeowners not tied to any tradesman platform. Runtime on the EGO's 2.5Ah battery is shorter than Milwaukee's 8.0Ah HIGH OUTPUT, but EGO's larger batteries extend this significantly.
