1. A machining tool comprising:
at least one plate-shaped cutting insert, which at least in sections comprises an impact and/or wear-resistant cutting material; and a cutting insert holder, the cutting insert holder having a cutting end, a shank end opposite the cutting end, an outer surface, an axis, and a fitting groove, the fitting groove having at least a first surface, a second surface, and a third surface, the first surface and the second surface spaced from each other, the third surface bounded by a first edge, a second edge, a third edge and a fourth edge, the first edge of the third surface extending along an edge of the first surface, the second edge of the third surface extending along an edge of the second surface, the third edge of the third surface toward the cutting end relative to the fourth edge of the third surface, the fourth edge of the third surface toward the shank end relative to the third edge of the third surface, a first portion of the third surface extending in a first direction through only a portion of the cutting insert holder toward the shank end of the cutting insert holder, a second portion of the third surface diverging from the first direction and extending in a second direction to the outer surface of the cutting insert holder, the cutting insert comprising a base surface and a cutting edge, the cutting insert bonded by a contact surface arrangement with the cutting insert holder directly via an adhesive layer, the cutting insert essentially having the shape of a prism, the cutting insert secured to the cutting insert holder in such a way that:
a) a base surface of the prism is adhesively bonded with the cutting insert holder over essentially an entire surface of the base surface;b) a jacket surface arrangement of the prism adjacent to the cutting edge is drawn to the cutting insert holder for spatially fixing the cutting edge; andc) a section of the jacket surface arrangement is caught in the fitting groove of the cutting insert holder. |
