The Covington 8" Grinder & Polisher is an excellent machine for grinding and polishing stones. With two hard wheels and one expandable drum, this unit will quickly shape and polish work pieces. The angled slots through the rubber rim of the drum allow it to expand when rotated, thereby locking the belt in place. The drum surface flexes to the contours of the gemstone quickly removing grinding flats and scratches. The hoods are easy to remove for cleaning or wheel changes. The water valve takes 1/4" OD plastic tubing for gravity water flow or 1/4" copper tubing for pressure systems. Spray nozzles under the hood wet the entire wheel face. This unit ships mounted on a rustproof aluminum-topped Lam-I-Cushion base.
The 8" Diamond Grinder/Polisher comes with two (2) 8" x 1-1/2" metal bond diamond grinding wheels (#100 & #220), three (2) 3" x 8" silicon carbide belts (#400, #600 & #1000), one (1) 8" x 1"-14RH aluminum head with leather disc attached and instructions.
NOTE ON SHIPPING: This is a very large and heavy item. It must be shipped via Toll Ipec courier.
