Three-dimensional grinding discs with overlapping layers of abrasive-coated, fiber-reinforced flaps that fan out from a central hub. As the overlapping layers of the flaps wear away, they continuously expose fresh abrasive mineral for a fast, consistent cut, while the cushioning of the flaps creates a smooth finish.Under normal conditions, flap discs will generate a finish that is one grade finer than the finish of a fiber disc of the same grade. And, because their overlapping construction allows more abrasive material to be loaded onto the cutting surface, they far outlast typical discs.By reducing steps and lasting longer, flap discs can greatly improve productivity in grinding operations.

Ceramic Alumina (Red) – The latest innovation in abrasives, this grain micro fractures to allow a continuous supply of the sharpest cutting edges. These discs provide the fastest cut as well as the best utilization of the entire grain for the longest life, especially on stainless steel and high alloy materials.

Zirconia Alumina (Blue) – An excellent blend of zirconia and aluminum oxide grain which provides a very good cut rate to cost ratio. This is a very good choice on carbon/mild steel applications.

Aluminum Oxide (Brown) – The original metalworking abrasive, this product is recommended for smaller jobs where a consistent, low cost product is needed.
