ABSTRACT:
An insert holder having a slot adapted to receive a cutting insert, a part of the slot being formed by a clamping arm. Two laterally opening seats are provided in the holder for receiving two spaced-apart projections of a key that is intended to bend the clamping arm outwards for widening the slot during the mounting and/or dismounting of a cutting insert. One of the seats has a cylindrical shape and defines a fulcrum for receiving the first projection, while the other seat has an oblong shape in order to effect outward bending of the clamping arm in response to displacement of the second projection along the oblong seat from a first point thereon located at a certain distance from the first fulcrum to a second point thereon located at a shorter distance from the fulcrum.
