Bit Holder And Base Part For Receiving A Bit Holder

摘要

The invention relates to a bit holder having an insertion projection and having a holding projection having a bit receptacle, the insertion projection comprising a bearing segment and the holding projection comprising a supporting segment. In order to allow the bit holder to be braced in permanent and stable fashion with respect to a base part, provision is made according to the present invention that the supporting segment and/or the bearing segment comprise two supporting surfaces and bearing surfaces, respectively, arranged at an angle to one another; and that the longitudinal center axis of the bit receptacle and the longitudinal axis of the insertion projection enclose an obtuse angle.

主权项

1. A bit holder, comprising:
an insertion projection having a longitudinal axis, the insertion projection including a bearing segment including at least one bearing surface; and a holding projection including a bit receptacle, the bit receptacle having a bit receptacle longitudinal center axis enclosing an obtuse angle with the longitudinal axis of the insertion projection, the holding projection including a supporting segment including at least one supporting surface; wherein the longitudinal axis of the insertion projection and the bit receptacle longitudinal center axis define a transverse central plane of the bit holder; wherein at least one of the at least one bearing surface and the at least one supporting surface includes two surfaces located on opposite sides of the transverse central plane, the two surfaces being arranged at an angle to each other and thus non-parallel to each other; and wherein the insertion projection includes an insertion projection front side facing in a tool feed direction, and the insertion projection includes on the insertion projection front side at least one pressure surface for impingement with a screw.
