A Disc with Precision Shaped Grain technology to deliver superior cut rates, while the flexibility of the flap construction enables grinding and blending in a single step.
Because the 3M Precision Shaped Grain generates an exceptionally high cut-rate with less pressure, operators can finish tough tasks like weld grinding, deburring, rust removal, edge grinding, weld seam blending, and deburring faster and with less fatigue. A heat-activated grinding aid on the disc makes this an outstanding product for all types of metalit helps keep the disc cooler on stainless steel and heat-sensitive metals such as nickel alloys and titanium, thereby reducing metal discoloration/oxidation and the chance of heat-related stress cracks. Discs with a 4-1/2in diameter have a max RPM of 13,300, and 7in discs have a max RPM of 8,600. Use Type 27 on flat surfaces or outside edgework.
