Milwaukee M18 FUEL Circular Saw
Score: 82/100Rankings
The Milwaukee 2732-20 is a heavy-duty, brushless cordless circular saw designed for professional framing, delivering power equivalent to a 15A corded saw. Its main trade-off is its significant weight and bulk, which can cause fatigue and reduce maneuverability in tight spaces. It is best suited for professional framers and carpenters who need cordless power rivaling corded tools for all-day jobsite use.

The Milwaukee M18 Fuel 6-1/2" Circular Saw is a lightweight, brushless cordless tool designed for professional framing and woodworking tasks. Its main limitation is an obstructed sight line at square cuts, which can affect alignment precision. It is best suited for professionals needing a compact saw for overhead or tight-space cuts in 2x lumber and OSB.
