Makita 9557PBX1 4-1/2-inch Paddle Switch Cut-Off/Angle Grinder – 7.5A, 11,000 RPM

Overview

Meet the Makita 9557PBX1 4-1/2-inch Cut-Off/Angle Grinder, engineered to handle cutting, grinding, and surface finishing in metalworking, fabrication, and renovation projects. Powered by a robust 7.5-amp motor, it delivers up to 11,000 RPM for fast material removal while a soft-start feature helps smooth the initial pull on busy job sites.

Designed for daily use, this grinder pairs durability with practical handling. Labyrinth construction seals the motor and bearings from dust and debris, while a protective varnish shields the armature for extended life. Weighing just 4.5 pounds, it stays nimble in overhead or tight spaces. An extra-large paddle switch, plus a lock-on/off option, enables comfortable control during longer sessions. The tool supports an AC/DC switch for powering from alternative sources and can be set up with a side handle on either side for operator convenience.
