Abstract
A flap disc for surface finishing a V-shaped work piece. The disc includes a backing plate and a plurality of abrasive flaps that are mounted on first and second sides of the backing plate. The abrasive flaps are radially disposed on the backing plate, each abrasive flap having an outer surface and an inner surface. A portion of the inner surface is adhesively attached to the backing plate. A second portion of the inner surface is disposed on the outer surface of an adjacent abrasive flap in an overlapping fashion so as to position the outer surface of the abrasive flap at an angle to the backing plate. The outer surfaces of the abrasive flaps on the first and second sides of the backing plate face in the same circumferential direction and taper radially toward one another to define a substantially V-shaped finishing surface.
