Description: |
| Abstract:
A method of clamping a tool-holder shank is described with reference to the turret of a boring-machine. The toolholder, in which tools are clamped at K, has its shank provided with flats D, E on opposite sides of the axis for engagement by set-screws for angular adjustment and clamping. The flat E is carried to the end of the shank to facilitate removal of the tool-holder, but the flat D is formed in a recess to prevent accidental dislodgment of the tool-holder during adjustment. |
