ABSTRACT:
The improved grinder of this invention is provided with a non-circular peripheral surface encompassing an output shaft. The non-circular peripheral surface is arranged to receive a mating hole in a grinder wheel guard. The grinder wheel guard is positioned on the grinder by means of a threaded fastener or the like and is sufficiently large to house an appropriate grinder wheel. The arrangement between the non-circular peripheral surface on the grinder and the mating hole in the grinder wheel guard provides a means for transferring any load imposed on the grinder wheel guard directly into the body or housing of the grinder.
