4-1/2" X 7/8" - Kelco Plastic Trimmable Flap Disc Abrasive

Zirconia Alumina/Ceramic, Plastic Trimmable Backing Flap Discs Ceramic grain has top size coating for cool, fast cutting Premium ceramic grain lasts 50% longer than zirconia and does not stain or burn material Made of hard zirconia alumina material which lasts longer than standard Zirconia abrasive material, built for a more robust and economical grinding wheel Trimmable plastic backing extends the life of the disc, is lightweight, and is cost effective 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 View our Exchanges and Returns Policy.
