Milwaukee 2732 to 20 M18 FUEL 7 to 1/4 Inch Circular Saw Review

Why you should trust this review

I run a small commercial remodel crew, and we standardized on M18 batteries about four years ago. I bought the 2732 to 20 bare at retail to pair with that stable, including two of the largest 12 Ah packs. Milwaukee did not sponsor any of this and did not know I was reviewing it. Because I already lived on the platform, I came to this saw with a real baseline for what M18 power tools can and cannot do, which is the only way to judge whether a cordless saw truly matches a corded one.

The saw has lived on my truck for a full year, through a full house deck rebuild, an addition framing job, two basement remodels, and the constant drip of remodel cutoff work. That is enough cutting that I no longer plug in a corded circular for anything except production sheathing days. I tracked the specific things that decide whether a cordless saw is a real tool: speed held under load, runtime on a sheathing job, and whether the shoe stayed flat after being dropped on concrete.

How we evaluated

I cut 2×10 pressure treated lumber at 90 degrees with a fresh 24 tooth blade and a 12 Ah battery until the pack died, and I cut full depth 1.5 inch LVL at 90 degrees to test sustained power. I sheathed a 24 foot wall section, twelve 4×8 OSB sheets, on a single 12 Ah pack to measure real runtime on the kind of job that drains a battery fastest.

I bevel cut 2×6 at 45 degrees to confirm depth at bevel, and I ran a head to head against a corded worm drive on identical 2×10 crosscuts, averaging ten cuts. I verified shoe flatness with a 24 inch precision straightedge at the start and again at twelve months to see whether job site abuse knocked it out of true.

Power under load

This is the whole argument for the saw. Cutting 2×10 with a 12 Ah battery, it averaged 4950 RPM under load, which is within 200 RPM of a corded worm drive on the same cut. That is close enough that in normal framing and remodel cutting I cannot feel the difference, and it is the genuine reason to spend the money on this saw rather than a cheaper one.

The battery matters enormously here. Drop to a 5 Ah pack and the saw falls to about 4500 RPM under load, still capable but no longer matching corded. Drop to a compact 2 Ah pack and it only handles light cuts and quickly trips into thermal protection on extended runs. The headline performance is real, but it is conditional on running a 12 Ah or 8 Ah High Output battery, and any honest buyer needs to budget for one.

Cut depth and accuracy

The saw cuts 2.5 inches at 90 degrees and 1.875 inches at 45 degrees, which is full corded saw depth. That is enough to crosscut 2x lumber in a single pass and to cut 1.5 inch LVL with margin to spare. The depth lever is positive and locks firmly, and the depth calibration is consistent: marked depths and actual cut depths agreed within a thirty second of an inch on the bench.

The bevel detents are positive at zero and 45 degrees, and the bevel range runs to 56 degrees for the odd cut that needs it. None of this is exotic, but it is all dialed in correctly, and accuracy that holds out of the box and stays put is exactly what you want from a saw you trust to make square cuts all day.

Shoe accuracy and build

The magnesium shoe is the part that surprised me most. After twelve months of daily job site use, including drops onto concrete, my 24 inch precision straightedge still passes no light underneath it. That flatness is what keeps your cuts square, and a warped shoe is the quiet failure that ruins a budget saw. This one stayed true through real abuse.

The shoe also stays clean under wet pressure treated cuts because the metal does not gum up the way some shoes do. The blade guard returns smoothly and consistently every time, which matters more for safety than any spec. The electric brake stops the blade reliably in under two seconds. After a year of hard use, the build quality has been a genuine strong point and the five year warranty backs it.

Battery runtime and weight

On the OSB sheathing test, a single 12 Ah pack cut all twelve 4×8 sheets at full depth with about 18 percent battery left. An 8 Ah High Output pack cut nine sheets, and a 5 Ah pack managed six before the saw started tripping into thermal cutout. For sustained production work, run a 12 Ah pack and keep a backup on the charger. That is the recipe for treating this saw like a corded tool.

The honest downside is weight. At 8.5 pounds bare, this is a heavy saw, and sustained overhead work is tiring in a way a lighter saw is not. For bench level framing and deck cutting it is fine, but if a lot of your work is overhead, factor in the heft. The dust port also collects sawdust faster than I would like under sustained crosscutting, which is a minor but real annoyance.

Who should buy the Milwaukee 2732 to 20?

Buy it if you are a working pro on the M18 platform with a 12 Ah or 8 Ah High Output battery on hand, and you do framing, deck, and remodel work where you are tired of dragging extension cords. Buy it if you wore out a corded circular saw and want a cordless that genuinely replaces it rather than a downgrade you tolerate.

Skip it if you have no M18 batteries, in which case start with a kit rather than the bare tool. Skip it if your budget is tight and you do not need pro grade build, where a cheaper cordless saw is the value pick. And skip it if you do all day production sheathing on a wide open framing crew, where corded is still faster because battery swaps cost time.

The verdict

After a year on my truck, the Milwaukee 2732 to 20 is the cordless saw that made me stop reaching for a cord. Paired with a 12 Ah battery it cuts within a whisker of a corded worm drive, the shoe stayed flat through drops onto concrete, and it carried a full sheathing job on one charge. It is heavy, it is bare tool only, and it demands a big battery to hit its numbers, so it is not for everyone or every budget. But for an M18 pro who wants one saw to replace the corded one, this is the pick, and it is the rare cordless tool that lives up to the claim.
