Makita GA4530 4-1/2″ Angle Grinder with Thumb Switch Corded

The Makita GA4530 4-1/2″ Angle Grinder is a compact corded grinder designed for metal fabrication, construction, maintenance, and shop work where control and reliability matter. Powered by a 6.0 amp motor delivering up to 11,000 RPM, it has the speed needed for grinding, cutting, and surface prep with standard 4-1/2″ grinding wheels, sanding discs, and wire cup brushes. The small 2-1/4″ barrel grip and 4 lb weight make this grinder comfortable to hold for extended periods, especially when working in tight spaces, overhead, or around complex parts.

To support long tool life in dusty environments, the GA4530 uses labyrinth construction to seal and protect the drive gear and bearings from contamination. A protective zig-zag varnish on the armature and improved thicker coil wires help reduce heat and energy loss, while all-ball bearing construction and a metal gear housing contribute to durability under regular use. With a thumb-operated body grip slide switch, side handle that can mount on either side, and a gear housing that can be rotated to suit different grinding and cutting positions, this 4-1/2″ angle grinder is built for practical, everyday use in the shop or on site.
