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.
