Flap Wheels and Specialty Abrasives

Flap wheels and specialty abrasives include cartridge rolls, cross pads, drum sleeves and flap discs made from coated or nonwoven abrasives. This product category also includes convolute, laminated cotton, and unified wheels. Cartridge rolls, cross pads and drum sleeves are used to sand, grind, debur or finish smaller, hard-to-reach bores, cavities or recesses. Flap wheels and flap discs are suitable for long-term use because new grains are exposed as products wear down. Abrasive flaps radiate out from the center of the wheel where the flaps are bonded together. Non-woven discs and convolute, laminated cotton, and unified wheels are used extensively in industrial deburring and finishing applications. Important specifications for flap wheels and specialty abrasives include outer diameter (OD), shank diameter, and bore diameter. Bore is the inner diameter (ID) of a center-mounted abrasive product. Shank diameter measures the diameter of an integral shank, pin, shaft or mandrel on mounted points or wheels.
