The invention relates to a tool intended for chip removing machining, including a holder (2) having a seat (9) formed in a top side for a cutting insert (1), which is clampable by means of a clamping mechanism that comprises a clamping body (16) provided with a finger (18), being movable inside a cavity (19) in the interior of the holder and co-operating with a screw (17) in a bore (20) in the holder. Said bore ports in a side, separated from the top side (4) of the holder (2), with the purpose of enabling access to the screw (17) from another direction than the top side. The screw is formed with a thick, first portion (21), as well as a thinner, second portion (22), having a male thread which is in engagement with a female thread in a through hole in the clamping body (16). Characteristic of the invention is that the bore (20) in the holder (2) is cylindrical and has a smooth surface, and that the thick portion (21) of the screw has a cylindrical, smooth envelope surface and is rotatably mounted in the bore. In addition, the cavity (19) in the area opposite the bore (20) is surrounded by a front wall portion (27), which is located in connection with a free edge along the bottom (10) of the seat (9). <IMAGE> |
