Norton® BlueFire® 66254461219 R884P Semi-Open Standard Density Coated Abrasive Flap Disc, 7 in dia, P36 Grit, Extra Coarse Grade, Zirconia Alumina Plus Abrasive, Type 27 Flat Disc

Flap discs are versatile grinding and finishing tools with three main components - backing plate, adhesive, and abrasive flaps. The flaps wear during use continually exposing new abrasive grain. The different variations of the components provide a variety of applications, ranging from heavy stock removal to blending to finishing. Flap discs are designed for portable grinder applications and can combine the 2-step stock removal and finishing operations of depressed center wheels and fiber discs into one operation.
