All Kelco flap discs are manufactured with hard-pressed flaps. A standard flap disc with non-pressed flaps tends to “chatter” during the grinding process, generating vibrations and resulting in the grit pulling away from the mounting prematurely. Hard pressed discs allow for the following:

Regular grinding
Maximum grinding capacity
Longer service life (2-3 times the longevity of non-pressed flaps)
Minimized risk of flap tearing
