Abstract
A tool for use in an abrading or resurfacing machine includes a head portion, a shank portion and a base portion, the shank portion joining the head and base portions and having a shape that tapers outwardly from a narrow neck where it joins the head portion to the base portion. The tool is inserted into a pocket in an abrading wheel having the same shape as the tool. Because of the irregular shape, centrifugal force will not cause the tool to become dislodged. The tapered neck serves to distribute torsional forces imparted by an adjustment screw which alleviates metal fatigue.
