摘要： The present invention relates to a tool for chip removal including a holder (11) and a cutting insert (12) provided with a through hole provided to abut against a base surface (14) and support surfaces (15, 16) in a cutting insert pocket in the holder. A locking pin threaded into a boring (17) in the holder is received by the insert hole. The pin comprises a head (20), a waist (21), a conical portion (22) and a threaded portion (23), which pin portions have a common center axis (CL1) in an unloaded condition. The locking pin is of a quick action type. The boring (17) comprises an eccentric conical recess (28) provided to displace the cutting insert in direction towards the support surfaces in cooperation with the pin during tightening of the pin in the threaded part of the boring. The pin (18) is provided to be able to clamp both negative (12A) and positive (12B) cutting inserts in the insert pocket, by the head (20) and the waist (21) at a final phase of the pin tightening provided to elastically bend in direction from the support surfaces (15, 16). A transition (24) between the head and waist cooperates with a profiled hole (19B) in a first type of cutting insert (12B) while the head cooperates with a cylindrical insert hole (19A) in another type of cutting insert (12A).
