3M Cubitron Type 29, Flap Disc, Ceramic, 4-1/2" Disc Diameter, 40 Abrasive Grit

This flap disc is designed for low to medium-high pressure applications on flat surfaces or outside edgework, especially in paint prep and stainless steel fabrication where final finish and gouge resistance are important. With precision-shaped, triangular grain technology, it helps to deliver superior cut rates, while the flexibility of the flap construction enables grinding and blending in a single step. It also helps to reduce fatigue in tough tasks like weld grinding, rust removal, edge grinding, weld seam blending, and deburring. A heat-activated grinding aid on the disc 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.
