Definitions

  • said first member is a ring configured to be supported on and/or secured to an end of said drill element.
  • a so-called pusher ring is of particular interest and results in a simple construction of the rock drill bit if the rock drill bit also comprises means for securing said second member and by that said rock drill bit to a said drill element.
  • the first member has neither to be secured to a drill element nor to said second member, but it will be kept in place by said second member.
  • a majority of said front buttons or all said front buttons are allowed to rotate about their own symmetry axes.
  • substantially used in the expressions “substantially a frusto-conical shape” and “substantially circumferential ring” also cover the case when cutting recesses or grooves and/or gauge buttons intersect the ring, as shown in the figures.
