This means that the torques to be transmitted between the collet holder and tool adapter are comparatively small. Therefore, it is sufficient in many cases when the torque transmission between the collet holder and tool adapter via the or the dowel pins.
- a particularly advantageous embodiment of the invention provides that the collet holder in the region of the plane surface one or more (radial) uten or
- the tool adapter in the region of the covenant also has one or more (radial) grooves or depressions, and that belongs to the interface a separate drive ring, which has at least one interlocking element, in the grooves or
- Depressions in the area of the plane surface and in the area of the federal can be used. In other words: Both the collar and the plane surfaces have only grooves or. Depressions on. As a result, the federal government and the flat surface manufacturing technology very easy and can be produced with high precision and axial runout.

- the diameter of the at least one through hole in the driving ring can be so large that
- the dowel pin can be screwed through the driver ring into the tool adapter and removed from it.
- the dowel pin can not be removed as long as the drive ring is in place. Then the tensioning pin secures the driving ring against
- the driving ring also serves as VerlierSich réelle for the dowel pins. Namely, if the dowel pin is turned out too far, then it hits against the drive ring and can not be unscrewed further.
- Mitallerings is slightly larger than the nominal diameter of the dowel pins or. Then that is the tension pin a Be screwed piece in the stepped bore. Only when the diameter of the stepped bore is reduced, the clamping pin abuts against the driving ring and can not be further unscrewed. In this position, the dowel pin also serves as VerlierSich réelle for the drive ring, so that a tool adapter can be replaced without the risk that the
- drive ring according to the invention has even more optional functions.
- the ejection of the tool adapter can also by
- Loosening / unscrewing of the dowel pins are actively supported. This can be done by a suitable design of the
- Collet holder can be realized. As a result, both alternatives lead to an axial force being exerted indirectly by the one or more clamping pins on the driving ring on the tool adapter, which supports the ejection.
- the dowel pin axially offset against an edge or a chamfer at the transition from the inner larger diameter to the smaller diameter of the through hole. This staggered pressing the dowel pins causes the ejection of the tool adapter, but at least supported.
- Through hole may be formed with a larger diameter than the cone, which is offset slightly in the axial direction to the longitudinal axis of the internal thread.

- the through-bore 225 of the driver ring 220 is designed as a stepped bore (see FIGS. 7 and 8), and that the transition between the two bore diameters is in the form of a truncated cone Countersink 318 is formed.
- This variant is not shown in the figures. Their function corresponds to that of the exemplary embodiment according to FIGS. 24 and 25.
- the offset "V" between the longitudinal axis of the internal thread 315 or the clamping pin 210 and the countersink 318 is important.
- Countersink 3318 to arrange. In the first case, results in a somewhat "nicer" look, because the clamping pin 210 sits centrally in the through hole 225 for the user. In the second case, the production is a bit easier.
