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.

In a motorized floor finishing machine having at least one circular plate having a central hub projecting out from a first major surface of the circular plate and adapted to be attached to a motor driven drive shaft, the improvement comprising:
- an abrasive member attached to a second major surface of the circular plate, said abrasive member being a metal bar of a predetermined length and having a generally circular cross-section over a predetermined arc with diamond particles brazed on an exterior surface thereof and arranged such that when the abrasive member is attached to the circular plate, a longitudinal axis of the abrasive member is parallel to the plane of the circular plate.
