Product Details
The 3M™ flap wheel type 84 747D measures 2" x 1" x 1/4-20 and features an 80 grit external abrasive made from a ceramic and aluminum oxide blend. Each flap is coated with this ceramic abrasive mix designed through a proprietary process to enhance grain toughness and hardness, providing a harder, longer-lasting abrasive suited for light to moderate stock removal and surface preparation. The abrasive is bonded to a flexible X-weight cotton backing with a resin bond that resists thermal and chemical deterioration during high-speed sanding, ensuring faster cuts and a higher cut rate. Additionally, the wheel includes a grinding aid for cooler running on stainless steel. The flap wheel’s design allows the flaps to wear away gradually, exposing fresh abrasive material for consistent sanding throughout its usage. This coated abrasive flap wheel is ideal for light grinding, blending, graining, and scale removal across various metals and is available in flange mounted and spindle mounted constructions. It is commonly used in metal fabrication industries for blending, descaling, refining, and setting the grain.
