The DeWalt DCG413FB  small Flat Head angle grinder features a brushless motor for an extended motor life and no need to change out old brushes.

The grinder’s wheel stops within 2 seconds or less. And, its Kickback Break engages maximum force to stop the wheel when there is a pinch, stall, or bind-up to reduce kickback, and will shut off for further protection.
