Abstract
A holder is designed to receive a cutting insert intended for parting and grooving operations. The insert is clampable in a seat formed between a blade tongue and a clamping finger which respectively extend from lower and upper front parts of the holder. A gap separates those front parts in order to enable those parts to be forced towards each other by means of a clamping mechanism mounted in the holder. The clamping mechanism comprises a drawbar, a first end portion of which is movable within a bore formed in one of the front parts, and a second end portion of which is fixed in the other front part. The first end portion of the drawbar includes a head having a frusto-conical abutment surface. A tightening screw is threadedly mounted in the same front part as the head and is arranged to contact the abutment surface to displace the drawbar in a direction forcing the clamping finger and the tongue together to clamp the cutting insert in place.
