Chip cutting tool

A chip cutting tool, preferably a parting or groove cutting tool, comprising a holder body, a clamping arm attached to said holder body, preferably integrally therewith, a cutting insert, said cutting insert being clamped by means of said clamping arm in an insert site in said holder body between a first supporting surface on the holder body and a second supporting surface on the clamping arm, said clamping arm being adapted to rest against the cutting insert in a generally bent state and clamp the cutting insert by means of the resilient force arising from the bending of the clamping arm, characterized in that an edge surface of the cutting insert opposed to said first supporting surface comprises a plurality of mutually inclined portions, which are intended to slide against said second supporting surface during insertion of the cutting insert into said insert site while simultaneously bending the clamping arm, said portions being mutually designed such that a larger bending of the clamping arm is obtained during an initial phase of the insertion of the cutting insert than during the final phase thereof, and in that the cutting insert is provided with an abutting surface which is adapted to define the final position of the cutting insert in the holder body by abutment against an end surface on the clamping arm.
