Operate your right angle grinder efficiently with the lightweight and durable BlueFire® R884P coarse grit center mount plastic heavy duty flat flap disc. The high performance zirconia alumina plus abrasive extends the life of the disc up to 30% and provides a consistent cut during coarse grit blending, deburring and stock removal. The jumbo semi-open flaps reduce loading when used on soft metals, and the fiberglass/resin backing plates absorb vibrations, improving operator comfort.
