Mixed Ceramic Abrasive
Each flap on the 3Mâ„¢ Flap Wheel 741A is covered with a ceramic abrasive mix, which was designed using a proprietary process to enhance toughness and hardness of the grain. For increased performance, this mix features aluminum oxide blended with 3M ceramic grain to create a harder, longer-lasting abrasive. Perfect for light to moderate stock removal, ceramic abrasives are engineered to cut fast and handle intense heat and stress applications. Ceramic/aluminum oxide blend surpasses aluminum oxide abrasives in cut-rate and durability and makes 3M Flap Wheel 741A an excellent choice for moderate stock removal and surface preparation.
Tough Construction
The abrasive mix is attached to a flexible backing using a resin bond. This resin bonding material is specially designed to resist thermal and chemical deterioration, which can occur during high speed sanding. This bond is very hard which allows for faster cuts and a higher cut rate. Each flap uses an X-weight polyster/cotton backing, which provides a tough, but flexible surface that bends to fit any work piece. As the wheel is used, the self-cutting flaps wear away to expose sharp, new abrasive material, assuring that surfaces are sanded consistently throughout the life of the wheel.
Flap Wheel Design
Coated Abrasive flap wheels are the ideal choice for light grinding, blending, graining and scale removal on a variety of metals. The abrasive flaps offer a long lasting supply of fresh abrasives and a load resistant design. Available in both flange mounted and spindle mounted constructions with general purpose aluminum oxide or high performing 3M ceramic aluminum oxide blend abrasive grain.
