Resinoid wheels are used for grinding speeds up to 16,500 SFPM. Their main use is in rough grinding and cutoff operations. This bonding material is used when heat generated by grinding must be kept to a minimum. Silicate bonding material releases the abrasive grains more readily than other types of bonding agents.
