Our take on the Milwaukee M18 18V Lithium-Ion Brushless Cordless 7-1/4 in. Circular Saw (Tool-Only), Model 2631-20

The Milwaukee 2631-20 is a tool-only 18V cordless circular saw with a brushless motor spinning a 7-1/4 in. blade at 5,000 RPM. It cuts 2-1/2 in. deep at 90° and 1-7/8 in. at 45°, bevels to 50°, and uses magnesium guards and an aluminum shoe to keep weight down. It suits M18 owners who already have REDLITHIUM batteries and want a full-size framing and decking saw. Against brushed 18V saws it runs cooler and longer; against rear-handle and 36V saws it gives up some power and runtime.

What reviewers say

Owners of the 2631-20 generally rate it as a reliable, light full-size cordless saw for framing and trim work. Most praise the power and cut quality on an M18 battery; the common complaints are runtime on smaller packs and the lack of an electric brake.

What people mention
  • PowerPraisedOwners say it cuts 2x lumber and plywood cleanly and quickly on a charged M18 pack.
  • WeightPraisedThe magnesium guards and aluminum shoe make it lighter than many full-size cordless saws.
  • Battery runtimeMixedRuntime is fine on high-capacity packs but short on smaller batteries.
  • BrakeCriticisedReviewers note there is no electric brake, so the blade keeps spinning after the trigger is released.
  • DustMixedThe blade-left layout gives good visibility but sends dust to the right side.
