Flap wheel is a versatile, high performing abrasive tool designed for grinding, deburing, cleaning and polishing of small diameter, tubing, concave and convex surfaces, small openings, channels and recessed areas on a variety of surfaces. Flap wheels are made out of coated abrasive flap. These flaps are reinforced at the center with a strong, flexible resilient adhesive. The salient feature of the flap wheel is that it is non-loading and non dulling because of the unique nature of flaps wearing away evenly in use. These provide consistent finish in uniform rate of cut. Flap wheels are available in a variety of sizes, and are made from resin bonded aluminium oxide cloth. 50 nos.
