Diamond grit impregnated dressers are have been derived from multi point diamond dressers. However, in contrast to the latter, diamond grit dressers are fabricated from crushed diamond grit available in natural as well as synthetic form, instead of large number of small natural diamonds. The outstanding sharpness of these tools is their biggest advantage and they also help in restoring the effective roughness of the surface of the wheel. Another major advantage is that these tools do not require any resetting as the diamond particles are fully consumed, thus, resulting in reduced inventory level.

Another reason for the popularity of these tools is the low initial cost and also low cost of maintenance. The resistance of diamond grit impregnated dressers to shock and impact makes these tools highly durable.
