Long-life radius diamond grinding wheels are the newest addition to PAVE TECH’s JAWs Diamond Tools. Works on pavers, wall caps, wall blocks, natural stone, anything that you need to soften the edge. Ideal for the cap edges around the top of a seating wall to make it more comfortable on the back of legs. Different radii available depending on desired curve. They also include water-feed holes for use with a wet polishing grinder. Will mount to any grinder with 5/8 in – 11 thread.
