Abstract

Perfections in pointed tools for drilling with a tool holder and a pointed blade that is held in a holding groove of the tool holder by means of a clamping screw that traverses the clamping groove transversely with reference to the clamping surfaces of the tool. It, with the tip of the blade emerging out of the gripping groove in the forward direction and the blade resting on a buttress surface in the gripping groove preventing a lateral turning of the blade, characterized in that the side of the blade opposite the tip is configured as a second tip, whose shape corresponds to that of the first tip.
