4-inch Aluminum Backplate for Diamond Abrasives

The 4-inch Aluminum Backplate for Diamond Abrasives provides a rigid, lightweight foundation for mounting diamond abrasive pads on an angle grinder. With a 4-inch (100 mm) diameter and a 5/8"-11 thread, it mounts to standard grinders and uses a hook-and-loop surface for quick pad changes in tight spaces, delivering controlled material removal on granite, marble, concrete, and tile.

Features & Specifications
