- 91AB Semi-Friable Mixed Premium Aluminum Oxide: Advanced grain technology used in combination with WA for general and various materials. This grain can be used to grind steels in either soft or hard state.
 - 83A White Aluminum Oxide: The high friability of this grain allows for fast, cool cutting of all steels. Induced porosity wheels are ideal for steels Rockwell C 55 and over.
 - PA Pink Aluminum Oxide: Excellent for grinding pre-hardened carbon steels.
 - AZ Premium Blue Aluminum Oxide: Recommended for hard steels and stainless steels.
 - 72C Black Silicon Carbide: Use for grinding non-ferrous materials, plastics, cast and gray iron.
 - AS3 Advanced Ceramic Grain: Ceramic Aluminum Oxide – Recommended for tool steels, sprayed metal coatings and high-temp alloys.
 - For horizontal spindle, rotary and reciprocating tables use wheels T-1, T-5, and T-7.
