Work with increased comfort thanks to the vibration-absorption properties in the fiberglass/resin backing plates of this Charger R822 coarse grit center mount fiberglass heavy duty flat flap disc. This disc pairs with your right angle grinder for coarse grit blending, beveling, deburring and stock removal, and the disc's high-density, jumbo semi-open flaps act like a finer grit by minimizing loading on soft metals. Its zirconia alumina abrasive provides an excellent cut with a total performance that's two to three times that of aluminum oxide products and well-suited for work with mild carbon steel.
