Medalist YP 2788 R Flap Discs, Type 27, 4 1/2 x 5/8 in, 40 Arbor, 33,300 rpm

Achieve an exceptionally fast cut rate and long product life from our new super sharp, 100% ceramic grain that defies premature dulling with optimum resistance to wear. Eliminate burn (with our grinding aid lubricant) and produce excellent part finishes that competitive blocky grains cannot deliver. Gain life and performance from our new, stronger, thicker engineered, Y-weight Plus polyester flaps. Increase amount of usable flaps from our quick- trim plastic backing that wears away with our self-sharpening abrasive. Grind and finish at the same time; no switching from depressed center discs to resin fiber discs.
