Black Magic Resin Cup Wheels allow true chip-free beveling. Utilizing RGT technology the Black Magic has the feel of a polishing pad -light weight and very smooth cutting, but is as aggressive as a diamond cup wheel. The Black Magic wheel is extremely versatile and can be used for beveling on natural stone, porcelain, UCS material, removing mesh backing, and creating a smooth finish on the underside of countertop overhangs.
