Get up and Grind! The 3M Silver Depressed Center Grinding Wheel is a heavy-duty wheel designed for use in aggressive grinding applications like beveling, slag removal, weld grinding and edge work on a variety of metals. You can rely on this wheel to help you to tackle your toughest grinding applications.  The 3M Silver Depressed Center Grinding Wheel features 3M Precision-Shaped Grain which continually fractures into super-sharp points and edges that slice cleanly through metal, rather than gouging or plowing as traditional abrasives do. This also helps it to last significantly longer than conventional ceramic grain abrasives while maintaining a high cut-rate over the life of the wheel.

Powered by the legendary speed and long life of 3M Precision-Shaped Grain, these new products are ideal for a wide variety of metalworking applications like weld removal, beveling, edge chamfering and more – offering a longer life and faster cut than aluminum oxide, alumina zirconia and other conventional ceramic abrasives.
