Overview
Angle grinder model WT8151 spins at 8500 RPM on battery power, built for cordless cutting and grinding rather than corded, continuous-duty work. Disc size and battery voltage are not stated in this listing.
8500 RPM sits toward the middle of the typical speed range for angle grinders, and running on battery power trades some continuous torque for portability compared with a corded model. No disc size or battery voltage is listed, so runtime and cutting capacity will depend on the battery pack it pairs with.
