DeWalt DCG413B 20V MAX XR Angle Grinder: What to Know
The DCG413B is DeWalt's 20V MAX XR small angle grinder, built around a 4-1/2" disc and a brushless motor DeWalt rates at roughly 9,000 RPM no-load. It uses a paddle-style trigger rather than a slide switch, which most users find easier to control one-handed, and the guard and disc-retention nut are both tool-free for faster wheel changes.
On safety, DeWalt documents two distinct systems on this model: a kickback brake that engages when the electronics sense a pinch, stall, or bind-up event and brings the wheel to a stop in about two seconds, and a separate electronic (no-volt release) switch that prevents the motor from restarting on its own if the paddle was left depressed when the battery was removed and reinserted. Both are real, manufacturer-documented features rather than marketing language, which matters in a tool category where disc bind-up is a genuine everyday hazard.
This is a bare tool: the DCG413B ships without a battery or charger, and DeWalt sells the same grinder bundled with unrelated tools (for example, paired with an impact driver kit) under different Amazon listings, so buyers need to read the exact listing carefully rather than assume a battery is included. Buying into this grinder also means buying into DeWalt's 20V MAX platform specifically; the battery is not interchangeable with Makita, Bosch, Metabo, or SKIL packs.
