Abstract
A drive plate for a concrete or stone grinding/polishing machine includes one or more abrasive elements in the form of short steel cylinders having diamond crystals captured in a hard and durable brazing alloy. Due to the round profile of the abrasive elements, as the drive plate is rotated by a drive motor, the abrasive elements are able to more readily strip mastic, sealers, glue, or most any thin film topical coating present on concrete or other hard floors.
