Definitions

  • the tool holder comprises at least one locking part, ball or cylinder, movable in a substantially radial direction, which limits the axial mobility of the rod, or drill bit, by penetrating into the cavities of that -ci, closed on both sides in the axial direction.
  • these balls or cylinders ensure not only the locking of the sliding but also the locking in rotation, by playing the role of coach.
  • the tool holder comprises, in addition to the locking piece (s), at least one rotary drive in the form of a key. and often two diametrically opposite.
  • a drill bit thus arranged can, as we can see, fit as well in the tool holders of the type described in FR 1,588,841 (HILTI) as in the types of tool holders described in FR 76 34 195 (BOSCH), c that is to say to one or two locking balls and one or two drive keys.
  • this drill may not be retained, in 50% of cases, in the tool holders with a locking ball, because it then occurs in the drive groove fully open towards the rear.
  • the associated drive groove creates in the locking groove an opening in its rear end surface, which prevents the passage of the ball only by the stops formed by the two transition zones between the edges of the groove. and the rear part of the drive groove.
  • the invention also provides for angularly shifting the drive groove relative to the associated locking groove so as to reduce one of the projections to the benefit of the other, the increased depth of which will then surely ensure good locking.
  • the drive groove is offset so as to make the lateral faces of the two associated grooves practically coincide, in the drill drive zone, that is to say practically canceling the projection corresponding to the zone drive, in order to extend the friction zone over a larger surface.
  • the drill comprises two diametrically opposite locking grooves 1, 1 ′, a third locking groove 2 at 90 ° from the first two, a driving groove 3 almost diametrically opposite to the locking groove 2 and a second drive groove 4 with a longitudinal axis parallel to that of groove 2 but offset here radially from it by 5 °.
  • This offset from the axis of the groove 4 has the effect of causing the lateral faces 5 and 6 of the two grooves 2 and 4 to be practically merged in the drive zone (b) of the drill bit, and on the other hand to spare, in the opposite zone, of transition between the lateral faces (a) and (a ′), a projecting surface 7, ensuring sufficiently the retention of the drill by abutment of the ball against this surface 7.
