8" Deluxe Combo Diamond Unit - 447DDC

The Covington 8" Deluxe Combination Unit (Power Feed Model) is designed for cutters who want a complete trimming, grinding, sanding, and polishing system in one compact package. This heavy-duty workstation features **two independent motors**—one for the 10" trim saw and one for the grinding station—so you can cut and finish your pieces with consistent torque and smooth performance. Ideal for hobbyists and production cutters alike, it arrives fully assembled and ready for use.

This Deluxe Diamond Unit includes everything needed to take your stones from rough to a finished polish. Covington’s metal-bonded wheels, expandable drum, diamond discs, and leather pad provide a full progression of grits, while the built-in spray nozzles ensure even water coverage across the entire wheel face. A removable hood makes cleanup and wheel changes simple, and the included diamond compound, extender fluid, polishing accessories, and instructional materials offer a complete turnkey setup.
