Overview
Not a full size corded saw, this DEWALT is a battery powered saw built for wood. A brushless motor spins a small blade with twenty four teeth, and a brake stops it after the trigger is released. The handle is plastic.
A small blade and light cordless body suit trim, plywood and tight jobs where a bigger saw is awkward. The brake is a safety and time saving feature. The listing names the saw only, and a battery is required separately.
Who it's for
A remodeler cutting plywood, trim and thin boards benefits from the light, compact design. Anyone ripping thick framing lumber or starting without batteries should choose a larger saw or a kit.
Pros and cons
- Compact and light
- CSA specification listed
- Battery required separately
- Small cutting capacity
- Wood surface only recommended
Performance notes
A brushless motor wastes less energy as heat, so it can run longer per charge. The electric brake stops the blade quickly once you release the trigger. The small blade limits depth, so it handles trim and sheet goods rather than thick lumber.
