The Milwaukee 4-1/2 in. Small Angle Grinder features a powerful 7 Amp motor and 11,000 RPM, making the tool an excellent choice for a variety of grinding jobs. The multi-port exhaust reduces motor burn-up by efficiently venting hot air out of the grinder. Debris baffles protect the internal components by deflecting debris out of the airflow at the intake vents. The burst-resistant guard offers safe operation.
