Abstract

Drill grinder has a grinding surface peripherally on an end face of a grinding wheel, and a drill guide with a guide body with bores axially of the disc and guide pins engaging in the flutes and limiting its rotation, with adjustable spacing to the grinding face. The guide pins are fast to the guide body and this and the grinding disc are axially displaced by a thread for adjusting their mutual spacing. A displaceable stop is on a part which rotates during the axial displacement, and then co-operates with a cam fast to the housing and a setting scale. The apparatus is simple to manipulate and the spacing of the guide pins from the grinding disc is easy.
