Discover a new class of right-angle abrasives. Triangular ceramic grains have self-sharpening ability to retain their sharpness in three steps. The surface heats up slower during grinding, producing less smoke and leftovers. It also needs less pressure to perform the task, allowing the operator to finish the task with less fatigue. 3M™ Silver wheels are an ideal choice for applications like weld removal, bevelling, edge chamfering and more – offering a faster cut and longer life than aluminium oxide and alumina zirconia wheels.
