Abstract

A rock drill has an axially extending shank (1) with a drill head (2) on one end. The drill head (2) has an end face (3) with a cutting blade (4) and cutting pins (5) extending outwardly from the and face in the drilling direction. The cutting blade (4) extends, diametrically across the end face and projects radially outwardly from the drill head (2) said axially outwardly from the end face (3). The cutting pins (5) are arranged on a diameter of the drill head which forms an acute angle relative to the cutting blade (4). Due to the acute angle between the cutting pins and the diametrically arranged cutting blade, removal grooves extending axially from the end face can be enlarged.
