9557PBX1 Angle Grinder, 4.5-In., 7.5 Amp, 11,000 RPM

The Makita 9557PBX1 is a versatile 4-1/2 inch cut-off and angle grinder built for cutting, grinding, and polishing applications. Its powerful 7.5 amp motor delivers 11,000 rpm for high-output performance. This corded grinder combines industrial-grade power with thoughtful design features that reduce fatigue and extend tool life in demanding work environments.

Dust and debris are constant challenges in grinding and cutting work. The 9557PBX1 addresses this with labyrinth construction that seals and protects the motor and bearings, plus protective zig-zag varnish that shields the armature—both engineered to prevent premature wear. The extra-large paddle switch provides comfortable operation, while the side handle installs easily on either side for versatile grip options.
