Makita GA9031Y Angle Grinder

Makita’s 9-Inch Angle Grinder (model GA9031) combines 15 AMP power with ease-of-use and motor protection features for longer-lasting performance in industrial and commercial environments.

15 AMP Motor Delivers 6,600 RPM

The GA9031Y is powered by a 15 AMP motor that delivers 6,600 RPM for faster stock removal. The labyrinth construction minimizes dust and debris penetration into the motor and bearings for longer tool life. In addition, the armature is sealed by a protective zig-zag varnish which prevents contamination by creating a barrier under rotation, and wire mesh intake covers are engineered to prevent metal shards from entering the motor. The armature is supported by dual ball bearings and reinforced with a nylon retainer for improved durability.

The GA9031Y weighs only 14 lbs. and is built with comfort and ergonomic features for extended use. The grinder features an ergonomic rubberized handle engineered for lower vibration and can be installed on either side of the tool. The push-button rotatable rear handle has positive stops and can be positioned every 90 degrees for operator convenience. Additional convenience features include a “tool-less” wheel cover for easy guard adjustment, and externally accessible brushes for easy serviceability.

The GA9031Y is a versatile and powerful grinder engineered for demanding applications and is ideal for masons, welders, ship yard workers, automotive technicians, stone/tile work, HVAC, electricians, and general contractors for a range of industrial grinding applications.
