Norton 4-1/2 X 5/8-11 In. RedHeat R961 Flap Disc Plastic Type 27 Flat 40 Grit CA/ZA

Flap discs are versatile grinding and finishing tools having fNorton main components: abrasive flaps, flap density (how the flaps are stacked), backing plate (flat or conical shape), backing plate material (fiberglass/resin, plastic, aluminum). All flap discs have flaps that are overlapped and glued to the backing plate. The flaps wear during use exposing new abrasive grain. The different variations of the components above provide a variety of choices ranging from heavy stock removal to blending to finishing. Flap discs are designed for portable grinder applications and can be the preferred choice over depressed center wheels or fiber disc.
