Abstract

A driver or dogging element adapted to transfer torsion forces between a rotating outer tube ( 10 ) and a drill bit ( 1 ) of a down-the-hole hammer, wherein the dogging element ( 7 ) is made of a softer material than those parts ( 3, 4 ) of the drill bit ( 1 ) that co-act with the dogging element ( 7, 8 ).
