Abstract
Disclosed is a tool length adjustment system which allows the tool length to be adjusted without removing the tool from the tool holder. The tool length can be adjusted through the combination of an external circumferential adjustment ring which can be rotated while the tool is in the tool holder, thereby driving an adjustment key built into the tool holder via the use of drive balls which ultimately cause the rotation of the adjustment key.

- a tool holder with an upper end configured to attach and detach to a machine spindle and a lower end configured to securely receive a tool;
- an adjustment ring rotatably mounted around the periphery of part of the tool holder;
- an adjustment sun rotatably mounted within the tool holder;
- at least one rotational adjustment member rotatably mounted abutting and between the adjustment ring and the adjustment sun, and disposed such that the at least one rotational adjustment member rotates in response to rotation of the adjustment ring and the adjustment sun rotates in response to rotation of the rotational adjustment member;
- an adjustment key rotatably attached at a top end to the adjustment sun and rotatably attached at a bottom end to an adjustment screw;
- and
- an adjustment screw rotatably attached to the adjustment key and configured to interact with a tool directly or indirectly attached to the adjustment screw such that when the adjustment screw rotates relative to the tool, the tool is moved vertically.
