Full 2-1/2 In. DepthThe 2-1/2 inch cut depth gives you the capacity you need for common framing and sheet goods, so you are not fighting a saw that comes up short on everyday cuts. Built for the JobsiteMagnesium guards, an aluminum shoe, an electric brake, LED light, and an integrated rafter hook make this saw easier to trust and easier to live with on a real job.
Overview
The Milwaukee M18 Brushless 7-1/4 in. Circular Saw, Model 2631-20, is a cordless circular saw built for users who want full-size blade capacity on the Milwaukee M18 platform without stepping up to a heavier corded setup. This is a circular saw designed for wood cutting, framing, and general jobsite crosscutting and rip cutting. If you already run M18 batteries and need a bare tool that can handle everyday carpentry work, this one makes a lot of sense.
On the job, the big story is the combination of a brushless motor, 5,000 RPM blade speed, and a full 7-1/4 inch blade. That setup gives this cordless saw the speed and blade size most users want for framing lumber, subfloor, plywood, and general construction cuts. Milwaukee also calls out up to 40% more power than brushed saws and up to 30% more runtime than brushed models, which matters if you are trying to stay productive through repetitive cutting instead of babying the tool between cuts.
The 2-1/2 inch cut depth is a practical spec, not just a number on a sheet. It means the Milwaukee M18 Brushless 7-1/4 in. Circular Saw is built around true full-size circular saw work, not just light trim tasks. For framers, remodelers, punch-list contractors, and serious DIY users, that gives you the reach to work through common lumber sizes with the blade capacity expected from this class of saw.
Milwaukee built this saw with magnesium upper and lower guards and an aluminum shoe, which is the kind of material choice you want on a jobsite saw. It keeps the tool lighter than many corded options while still giving it the durability needed for transport, staging, and repeated use. Weight is listed at 7.2 pounds bare and about 9.0 pounds with battery, so it stays manageable for overhead pulls, ladder work, and moving around a busy site.
Jobsite details are where this model gets more useful day to day. The electric brake stops the blade after you let off the trigger, which helps with control between cuts. The LED light improves cut-line visibility in dim areas like basements, garages, and remodel spaces. The integrated rafter hook makes storage easier when you are working off staging or moving between cuts, and REDLINK intelligence adds overload and temperature monitoring to help protect both tool and battery in tougher applications.
This saw is part of the Milwaukee M18 battery system, so it is a better buy for users who are already invested in that platform. The tool is sold as a bare tool, which keeps cost down if you already own M18 batteries and chargers. It ships with a blade and blade wrench, so you can get set up quickly, but you will need to supply the battery and charger separately.
Who is this for? It is a strong fit for carpenters, remodelers, general contractors, maintenance crews, and serious homeowners who want a cordless framing saw with standard 7-1/4 inch blade size and real jobsite features. If your work is mostly sheet goods, framing lumber, deck boards, and general construction cutting, this model gives you the capacity and speed you need without overcomplicating the tool.
