Abstract

The rock drill bit consisting of shank (1) and drill head (2) is provided with a cutting tip (4) as well as cutting pins (5) at the front end (3) of the drill head (2) pointing in the feed direction. The diameter on which the cutting tip (4) is arranged and the diameter on which the cutting pins (5) are arranged form an angle deviating from 90 DEG . An enlargement of the disposal flutes (6) is made possible by the deviation in the angle of both diameters. <IMAGE>
