These 1 1/2 inch x 3/8 inch wheels are used for sanding and general clean-up of irregular or curved sections of wood, metal and fiberglass. They are self conforming on any shape or surface. They are ideal for hard to finish sharp corners, narrow channels, round concave or convex areas. As these flaps wear, new abrasive is constantly being exposed. Excellent alternative to wire wheel brushes, grit-impregnated nylon brushes, and fibrous wheels, all of which become less efficient with use. They are mounted on 1/8 inch shanks. This set contains grits of 60, 80, 100, 120, 150 & 180.
