Abstract (en)

[origin: WO9635856A1] Described is a drilling tool with a head whose end faces the direction of advance and has a main cutting face which forms a drilling point lying in the axis of the drill and slopes back on each side essentially in the shape of a roof, the main cutting face also having chip-removal grooves. The tool is characterized in that the main cutting face has a primary cutting edge, which extends radially along at least one side of the main cutting face, and a secondary cutting edge which extends radially along essentially the remaining length of the main cutting face and is set back longitudinally, in the direction opposite to the direction of advance with respect to the primary cutting edge by at least the distance in millimeters which the drill advances per rotation.
