About

The 4-1/2” X-LOCK Angle Grinder (GA4570) offers X-LOCK technology for quick tool-free wheel changes. A click-mount and pull release lever make changing wheels easy. The GA4570 weighs about 5 lbs. and is built with comfort and ergonomic features for extended use. It is ideal for efficiently grinding and cutting a wide range of materials including tile, concrete, pipe, conduit, and more.

The GA4570 is powered by a 7.5 AMP motor that delivers 11,000 RPM for the most demanding applications. The labyrinth construction seals and protects the motor and bearings from dust and debris 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. The ball bearing design and metal gear housing provide increased durability.

The GA4570 is a versatile and powerful grinder engineered for demanding applications including cutting, ferrous metal, paint and rust removal, shipyard maintenance, heavy machinery, metal polishing, general steel grinding, auto repair work, cutting brick and masonry, and restoration work. The grinder is built for welders, fabricators, plumbers, masons, electricians, automotive technicians, stone and tile workers, HVAC, and general contractors seeking a best-in-class industrial quality angle grinder.
