Abstract
A disposable insert is positioned on a pin in a stepped recess of a cutting tool shank. A slidable wedge positioning block and clamp member are carried on a screw at the rear portion of the stepped recess. Tightening the screw causes the clamp to clamp the top of the insert and the positioning block to wedge the insert forwardly against the pin to securely hold the insert.

A clamping tool holder comprising a tool shank equipped on its front end with a stepped recess, into the horizontal frontal lower face of which there is set a pin, on which a disposable pin-type cutting insert is placed, and from the rear upper face of which a screw thread extends into the shaft, in which a clamping screw is inserted which passes through a clamp;
- wherein a positioning block is located below the clamp which is slidably arranged in relation to said clamp, and which is fitted with an oblong hole, through which said clamping screw extends, and elements having a wedging action on the clamp and positioning block and rear wall of the shank recess, by means of which a clamping of the positioning block against one or more lateral faces of the disposable cutting insert is effected.
A clamping tool holder comprising:
- a tool shank having a stepped recess at one end;
- a pin extending upwardly from the lower face of said recess;
- a disposable pin-type cutting insert having a central hole therein and positioned on said pin;
- a threaded hole extending into said shank in the upper face of said recess;
- a clamping screw threadably engaged in said hole and slidably locating a positioning block adapted to engage the side of said insert;
