A tool post comprises a body upon which a tool holder is slideably mounted for vertical movement by means of a dove-tail slide and groove and the body has a slit therein which opens into the slide groove. A bolt passes through the slit portion of the body which has its end threadedly received in a block which is laterally movable by means of an eccentric. A vertical slot in the tool holder slide receives a fixed pin, and there is an adjusting bolt passing through the slot with a traveling nut which is engageable with the fixed pin to permit vertical adjustment of the tool holder.
