DeWalt DCS570B vs Milwaukee 2732-20: 20V MAX Against M18 FUEL 7-1/4 Inch Circular Saw

Where these two differ

Two 18V-class brushless 7-1/4 inch saws with electric brakes. The DeWalt DCS570B is cheaper, cuts a touch deeper and bevels to 57 degrees at 5,200 RPM. The Milwaukee 2732-20 is more powerful at 5,800 RPM with a magnesium shoe and guards and a 50 degree bevel. On deck boards both are fine; on wet joists the Milwaukee keeps cutting where the DeWalt slows.

This comparison is based on the published specifications and manuals for both saws and on recurring owner feedback. We have not run either saw ourselves.

Power

The Milwaukee on a High Output pack rips wet pressure-treated 2x without slowing much. The DeWalt rips the same board slowly and drains a small pack doing it. Dry lumber and deck boards cut cleanly on both.

Cut capacity

The DeWalt cuts a sixteenth deeper and bevels seven degrees further, which matters for a 4×4 in two passes and for steep rafter cuts on a pergola. Most deck and fence cuts never use either margin.

Build and handling

The Milwaukee magnesium shoe and guards are lighter and tougher than the DeWalt metal shoe and plastic guards. Both sit square on a cut and both have good line visibility through the shoe notch.

Batteries and runtime

20V MAX packs are cheap and plentiful; a FlexVolt pack gives the DeWalt long runtime. M18 High Output packs give the Milwaukee full power and run the Milwaukee yard range.

Blades and setup

Both take 7-1/4 inch blades with a 5/8 inch arbor. A 24-tooth framing blade suits both; a 40-tooth blade cleans deck board ends. Depth and bevel levers on both.

Yard jobs this decides

Deck boards, fence rails, pickets and raised beds suit both. Wet joists and beams favor the Milwaukee. A pergola with steep rafter bevels favors the DeWalt. The battery decides the rest; both platforms run a full yard.

Warranty and support

On the DeWalt DCS570B, DeWalt covers it with a three-year limited warranty, one year of free service and a 90-day money-back guarantee. On the Milwaukee 2732-20, Milwaukee covers M18 FUEL tools with a five-year warranty and M18 packs with three years. Both makers run service networks in the US and both honor the warranty only with proof of purchase, so keep the receipt with the manual. Registration takes a few minutes online and is worth doing the day the tool arrives.

Common owner complaints

DCS570B owners mention slowing in wet lumber and runtime on small packs. 2732 owners mention price and wanting High Output packs. Both are reliable.

Which one should you buy

Buy the DCS570B on DeWalt 20V for dry lumber at a low price. Buy the 2732-20 on M18 or for the more powerful, tougher saw.

Our verdict

The Milwaukee 2732-20 takes this comparison on power and build. The DeWalt DCS570B is the better value with more cut capacity.
