Viper Diamond Resin Cup Wheel, 4-Inch, 100 Grit

The Viper Diamond Resin Cup Wheel is designed for grinding, shaping and cleanup applications on natural stone, engineered stone, quartzite, ultra-compact surfaces and porcelain. Its diamond-impregnated resin is harder than the resin used in typical polishing pads, supporting long service life during fabrication work.

A lightweight aluminum backer adds rigidity, while the 100-grit resin surface provides controlled grinding and smoothing action. The cup wheel can be used wet or dry and is designed to produce clean grinds with minimal chipping.
