FIELD: metallurgy.

SUBSTANCE: tool holder is designed for bending tool having two surfaces of fixture and receiving groove with upper rim. A clamping case with the first clamping surface is designed for interaction with one of the surfaces of the tool fixture. A clamping strap serves for pressing the tool and is installed to perform pivot turning; this strap is equipped with the second clamping surface. The strap can be in the first position corresponding to clamping of the tool, and in the second position corresponding to fixing/removal of the tool. There is also a holding element with variety of plates parallel to each other and arranged in the same plane. Each plate of the holding element has two spring deformed sections and at least one bent part. One spring deformed section is directed up and has an end designed for entry into the receiving groove of the bending tool, and it also has the part designed for interaction with a lower rim of the receiving groove at the tool turn.

EFFECT: extended technological capabilities.
