Abstract
The present invention relates to a holder for a machining tool insert, in particular a lancing or cutting insert, having an approximately beam-shaped cutter holder, a cavity formed inside the end thereof, which serves as a receiving pocket for the tool insert and is bounded by clamping jaws that define the clearance width of the receiving pocket, a slot extending with a first end to within the proximity of the inner edge of the receiving pocket so as to permit elastic pivotability of one of the clamping jaws, and having a clamping arrangement comprising an actuation member for producing a clamping force that acts within the region of the slot upon the pivotable clamping jaw. In order to attain improved absorption of transverse force components acting upon the pivotable clamping jaw, it is furthermore provided in said holder that the second end of the slot extends within the proximity of the lateral edge of the cutter holder, with an elastic connecting web that bridges the second end of the slot being disposed between the pivotable clamping jaw and the cutter holder.
