ABSTRACT:
An adapter (12) is of channel shape having longitudinal projections (25) at its respective sides for engagement with undercut grooves (24) in a face of a casing of a powered grinding tool (10) with which the adapter is intended to be fitter to sharpen high speed drill fits, in use, by means of a grinding wheel (20) of the tool. The adapter has a rearwardly directed head (76) at its top, the head having a rotatable dial (85) mounted therein which is provided with a multiplicity of differently sized drill bit receiving openings (87), so that, in use, by angularly moving the dial, the opening for a particular size of drill bit can be brought to a location where the drill bit can be inserted in the hole and correctly worked by the grinding wheel, when the adapted is fitted to the tool.
