The white coloured wheel is at a higher price and is suitable for hard steel alloy tool steel, cutting faster and with less heat generated. The wheels break down and give a new cutting surface which means that the wheel will need replacement more frequently.

Ceramic aluminium oxide is a fast cutting abrasive with a limited amount of heat generated giving the least amount of tool burn. The blue coloured is more durable than the white version but does cost more. It is most suitable for high-speed steel tool sharpening.
