Polishing Wheels - MS Series Assortment - Model# PVAMSK
PVA Marble Edge polishing wheels are made in 5 different degrees of finish: Extra Coarse, Coarse, Medium, Fine and Extra Fine. The best results will be achieved if you use all five in order. They are designed for marble and related materials such as travertine and onyx. They should only be used DRY. Intended for final blending and polishing, they do not replace sanding belts or grinding wheels. The best results and longest tool life are achieved if you do not press hard -- just touch lightly. Too much pressure will serve no purpose and the wheel will heat up and wear out too fast. For 4" Disc Grinders (Do not exceed 12,000 RPM) 5 Grits 10 Pieces.
