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.
