Ceramic Alumina – The latest innovation in abrasives, this grain micro fractures to allow a continuous supply of the sharpest cutting edges. This provides the fastest cut as well as the best utilization of the entire grain for the longest life, especially on stainless or high alloy materials.

Zirconia Alumina – 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 – The original metalworking abrasive, this product is recommended for smaller jobs where a consistent, low cost product is needed.
