Fixture between an insert holder and a tool holder of a boring head

摘要

The cutter holder (9) has a conical transverse slot (13), and the tool holder (5) has a corresponding mating key (11) on its end face. The key is oversize in relation to the slot. Thus the tool holder and cutter holder, when tightening up a clamping screw (10) fitted more or less concentrically to the key, experience an elastic deformation. They lie flat and level with one another along the slot and key.
