Multiple layers of Zirconia cloth flaps constantly expose new sharp points to the work surface. These flaps are laminated by state-of-the-art automated equipment to a reinforced fiberglass backing that wears with the flaps and will not damage the work piece. This enables the operator the use of the entire disc for greater efficiency. Each disc is balance tested and will not vibrate, providing a smooth, cutting, long lasting sanding tool.

Type 27 discs have flat faces for grinding flat surfaces. Type 29 have slanted faces, which allow the grinder to be used at a more natural working angle.
