Our take on the DeWalt DCG408B 20V MAX Brushless Cordless 4 1/2 in. Paddle-Switch Grinder

The DeWalt DCG408B is a cordless 4 1/2 in. angle grinder built on the 20V MAX battery platform. Its brushless motor holds constant speed under load, and overload protection shuts the tool down before it overheats. It runs 4 in. to 5 in. wheels and ships with both Type A and Type B guards for 62841 compliance. The paddle switch starts and stops the tool with a grip of the body, and mesh screens keep debris out of the internals. It suits tradespeople already on the 20V MAX platform who want cordless grinding and cutting; bare tool only, so batteries and charger are extra. Against corded grinders it trades raw power for freedom from an outlet, and against smaller 18V rivals it offers a wider wheel range and dual guards.

What reviewers say

Owners rate the DCG408B as a solid cordless grinder that keeps speed up in cuts and survives dusty job-site use. Most praise is for the brushless motor and the safety guards; the common complaint is that it needs a good battery and is not a match for a corded tool on long, heavy jobs.

What people mention
  • Motor powerPraisedOwners say the brushless motor keeps wheel speed steady through cuts in steel and rebar.
  • Battery runtimeMixedReviewers report good runtime on light work but fast drain on continuous cutting and grinding.
  • Overload protectionPraisedUsers like that the tool cuts out under heavy load instead of burning up.
  • WeightCriticisedSome owners find it heavy and bulky once a large battery is mounted.
  • SwitchMixedThe paddle switch is seen as safe and quick by some and awkward to hold by others.
  • GuardsPraisedBuyers value getting both Type A and Type B guards in the box.
