Cut at a fast rate while enjoying improved grain retention and fray resistance when you attach the Blaze R980P coarse grit arbor thread fiberglass heavy duty flat flap disc to your right angle grinder. Its high-density, jumbo Y-weight flaps act like finer grits, and they absorb vibration to increase operator comfort. When blending, beveling, deburring and removing stock from chrome, cobalt, inconel, stainless steel, titanium and other hard-to grind materials, this flap disc’s latest-generation ceramic alumina abrasive lasts 50 to 200 percent longer than other flap discs.
