The Milwaukee 2739-20 M18 FUEL 12 Inch Dual Bevel Sliding Compound Miter Saw with ONE-KEY is a cordless 12 inch sliding compound miter saw built for professional carpenters, remodelers, and general contractors who need full-size cut capacity without dragging a cord around the jobsite. This is a miter saw designed for accurate crosscuts, bevel cuts, and angle cuts in trim, framing material, baseboard, and crown. Model Number: 2739-20.

What makes this saw matter is that Milwaukee built it to deliver the power of a 15 amp corded saw while still running on the M18 battery platform. That is the real selling point here. You get the portability of cordless with the kind of output and capacity people normally expect from a shop saw or a dedicated corded trim setup. Milwaukee rates it for up to 330 cuts per charge, which means it is not just a quick punch-list tool. It is meant to stay productive through real finish work and daily install tasks.

Capacity is where this saw earns its keep. It has a 6-3/4 inch vertical capacity with baseboard against the fence, a 2 x 14 horizontal capacity, and a 7-1/2 inch nested crown capacity. In plain terms, that means it can handle the kind of stock that shows up on trim and remodeling jobs without forcing awkward flip cuts or workarounds. The dual bevel setup adds more flexibility when you are fitting crown, casing, or detailed trim and want to keep your work moving instead of resetting material every other cut.

Milwaukee also paid attention to the parts that affect cut quality. The dual horizontal steel rails with three large linear bearings are there for smooth sliding action, and the adjustable stainless steel miter detent plate is built for repeatable angle settings. The cam locking miter system and detent override help when you need to move quickly between common angles or sneak into an angle that does not land exactly on a preset stop. The shadow cut line indicator is another feature that matters in day-to-day use because it gives fast blade alignment and accurate cuts without needing recalibration.

From a jobsite handling standpoint, this saw is easier to live with than a lot of full-size 12 inch units. The aluminum construction keeps tool-only weight at 47.6 lbs, and Milwaukee includes integrated top and side carry handles for moving it around. That lighter build matters when the saw is going from truck to stand, room to room, or up a flight of stairs in a remodel. The horizontal handle is also set up for comfortable on and off operation, which sounds small until you are making cuts all day.

On the electronics side, the saw uses Milwaukee's POWERSTATE brushless motor and REDLINK PLUS intelligence. That means the tool is designed to manage performance and provide overload protection during heavier applications. ONE-KEY adds tracking and tool management capability, which is useful for contractors trying to keep tabs on expensive equipment across crews and jobs. Battery compatibility is straightforward: it fits the Milwaukee M18 system, and the product information specifically notes battery not included.

This saw makes the most sense for finish carpenters, trim crews, remodeling contractors, and builders who want one cordless miter saw that can handle large material while still being portable enough for daily field use. If you are already on M18 and want a serious cordless sliding compound miter saw instead of a small-site compromise, this is the kind of tool that justifies its place fast. If you are expecting a bare tool to come with batteries, note that it does not. You get the saw and core accessories, but power comes from your existing M18 setup.
