Abstract

The drilling crown (1) comprises a work part (4), and a shaft (5) provided with a thickened section (6). In the set of tubes (3) are a spring (7) and a ring (8) which are so arranged that with return feed of the drilling machine, the thickened part locates against the ring. - Striking energy from the machine is transmitted to the spring which passes it on via the ring as a blow against the thickened part of the drilling crown.
