Great for Robotic Weld Grinding
In medium and high pressure applications like robotic weld grinding, it's important to choose a high performance abrasive that cuts fast and lasts long. The self fracturing mineral in the 3M™ Silver Depressed Center Grinding Wheel will keep your robot grinding welds long after other abrasives call it quits, reducing downtime and maximizing efficiency.

3M Precision Shaped Grain
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.

Advanced Series Abrasives
The 3M™ Silver Depressed Center Grinding Wheel is part of a new class of 3M abrasives designed to deliver an unbeatable combination of performance and value. Powered by the legendary speed and long life of 3M Precision Shaped Grain, these Advanced Series Abrasives 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.
