The flap discs of the FLAP type have been developed to satisfy the highest demands on primary deburring. The nylon lamellae are heavily impregnated with SiC particles. This combination results in superb deburring capacity with outstanding tool life. Specific properties of KUMEX FLAP flap discs provide removal of primary burrs without generating undesirable secondary burrs. Where certain process parameters exist, minimal or no brushing operations are required.

Flap discs are available in standard and hard versions. Standard hardness still allows for some tool flexibility, whereas the hard variant closely resembles a grinding wheel and is only used on two-dimensional surfaces.
