Discover the benefits of a long-lasting, value-priced grinding wheel. The 3M Silver Depressed Center Grinding Wheel is a type 27 bonded grinding wheel designed to deliver an unbeatable combination of performance and value. These long-lasting wheels use 3M Precision-Shaped Grain to deliver a fast and consistent cut during grinding and heavy stock removal on stainless steel, mild steel, aerospace alloys and more. This ceramic grain lasts exceptionally long, continuously fracturing into super-sharp points and edges that slice cleanly through metal. 3M Silver Grinding Wheels last significantly longer than grinding wheels made with conventional ceramic grain, while maintaining a high cut-rate through the life of the wheel. These 6-inch grinding wheels are suitable for use with either an electric or pneumatic angle grinder. As part of the 3M Advanced Series of abrasives, 3M Silver Depressed Center Grinding Wheels are engineered to deliver high performance at a budget-friendly price. They easily handle heavy grinding tasks like weld grinding, beveling, slag removal and edge work with either pneumatic or electric tools.
