Stone cup wheels for fast, aggressive removal of granite and marble. The turbo design includes two layers of diamond segments with spacing in between to keep the core and diamonds cool.This unique design helps to remove dust when used dry. When used wet the slurry is expelled quickly which keeps the operator working longer without stopping to clean out the cup-wheel. Resin filled diamond stone cup wheels are great for stock removal without chipping or shattering the edge of the stone. Color coded for ease of use, they have a recommended 12,000 operating RPM and can be used wet or dry.
