Abstract
A tool holder has a base element, a deformable receiver for clamping a tool and at least one locking element configured for preventing an axial extraction of the tool from the tool holder through engaging a corresponding opposite element at the tool. The at least one locking element is integrally configured in one piece with the receiver.
Claims20
A combination of a tool holder and a rotation tool, the combination comprising:
- a rotation tool having a shaft with an end face and a circumferential surface;
- a tool holder having a clamping chuck being a deformable receiver for receiving and clamping the rotation tool in a central axial opening thereof;
- a pullout preventer configured to lock said rotation tool in said tool holder against an axial migration out of said central axial opening of said tool holder;
- said pullout preventer including at least one locking element, being a part of said tool holder, and at least one locking groove formed in said rotation tool, with said at least one locking groove and said at least one locking element being complementarily formed and disposed to engage one another and to lock said rotation tool against the axial migration out of said tool holder.
1 more element
A rotation tool, comprising:
- a shaft with an end face and a circumferential surface, and a tool head opposite said shaft;
- said shaft being formed for insertion into a tool holder with a clamping chuck for driving rotation of the tool about a rotation axis;
- said shaft of said rotation tool being formed with at least one locking groove that begins at said end face and extends in, and terminates in, said circumferential surface;
- and
- said locking groove being formed for engagement by a locking element of the tool holder, that locks the rotation tool against an axial migration out of said tool holder.
2 more elements
A tool holder for a rotation tool, the tool holder comprising:
- a clamping chuck formed with a central axial opening for receiving and clamping the rotation tool therein;
- a locking element disposed to project into said central axial opening;
- said central axial opening forming a receiver for receiving a shaft of a rotation tool therein, wherein the shaft is formed with a locking groove configured to engage with said locking element that projects into said central opening and said locking element is configured to mesh with the locking groove and to lock said rotation tool against an axial migration out of said tool holder.
