Overview

The BLACK+DECKER BDEG400 is a corded electric grinder with an 800-watt motor spinning at 10,000 RPM. Weighing 2 kilograms, it runs on standard 120-volt household power.

The 800-watt motor and 10,000 RPM speed place it in line with compact angle grinders used for cutting, grinding and surface work, rather than heavy industrial grinders. Its corded design keeps power steady through longer jobs.
