The invention provides a toolholder (10) having a forward portion with a location for a cutting insert (11) having a central hole (14). A clamp (20) is arranged adjacent said insert location, said clamp being secured to the holder by means of a screw (22) that extends through said clamp. A coil spring (37) is surrounding said screw (22). The forward portion of the clamp is shaped as a first protrusion (23) intended to engage with the hole (14) of the insert whereas its other end is a second protrusion (26) intended to engage with an inclined contact surface (27) in the holder. The upper portion of the coil spring (37) is received in a bore (36) of said clamp that extends at an inclined angle ( alpha ) in relation to the central axis (C1) of said screw (22). <IMAGE> |
