The DeWalt DCG413H1 is a cordless 4-1/2 in. small angle grinder built on the 20V MAX XR brushless platform. Its standout safety package is a brake that stops the wheel in 2 seconds or less and a Kickback Brake that cuts power and shuts the tool off on a pinch, stall or bind-up. The kit pairs it with the Powerstack 5.0 Ah pouch-cell battery, which DeWalt claims delivers more power and work per charge than its standard cells. It suits metalworkers, welders and remodelers who want corded-like cutting and grinding without a cord, and it competes with brushless grinders from Milwaukee and Makita on safety electronics rather than raw size.

Owners of DeWalt's brushless 20V grinders generally rate the platform highly for power and the brake and kickback electronics, and the Powerstack battery draws praise for runtime. Complaints tend to center on weight with a 5.0 Ah pack and the paddle switch's ergonomics.
The DeWalt DCG413H1 is a cordless 4-1/2 in. small angle grinder with a paddle switch and a brushless motor. The brushless design means there are no brushes to change, and it offers a longer motor life and efficient runtime. It runs on a 20V MAX battery and has variable speed.
The grinder has several protections. A kickback brake senses a pinch, stall or bind-up, then stops the wheel with maximum force, reduces grinder movement and shuts the tool off. The brake stops the wheel in 2 seconds or less on average. A two-stage trigger requires two actions to start the tool. E-Switch protection requires the trigger to be cycled off and on to restart after a power outage or other unexpected shutdown.
The kit includes the DCBP520 POWERSTACK 5.0 Ah battery, which uses pouch cell technology. It has a non-marring over-molded rubber base that helps protect finished surfaces, and a 3-LED fuel gauge shows the state of charge. The battery is compatible with all 20V MAX tools and chargers.
