ABSTRACT:
A chip holder and a mounting device for the installation of a chip holder in cutting-tool bodies. The chip holder includes a male thread and one or more through, suitably peripheral recesses for accommodating torque-transferring fingers included in the mounting device, as well as for allowing passage of cooling liquid through a bore formed in the tool body in which bore the holder is placed. The mounting device includes one or more torque-transferring fingers, which have looking hooks in order to provisionally clamp the chip holder upon installation. Furthermore, the invention relates to a cutting-tool unit having an installed chip holder.
