Abstract: The present invention relates to a cutting tool preferably for milling. The tool comprises a holder (30) and a cutting insert (10). The cutting insert (10) has a generally circular basic shape and includes at least one cutting edge (16) created by the transition between an upper face (11) and an edge face (13) of the cutting insert (10). The upper face (11) is a rake face, and the edge face (13) is a clearance face. The holder and cutting insert have first means (37, 13b) for preventing rotation of the insert about a center axis (20). The clearance face is conical and converges towards a lower face of the insert. The first means for preventing rotation is provided distant from and radially short of the clearance face and at a part of the insert that is closer to the lower face than to the upper face so as to constitute an indication of fracture radially inside the conical clearance face. The holder and insert comprise second means (35, 13a) for preventing rotation of the insert. Also, said step constitutes an indication of fracture, and thereby a breakage of the cutting edge is better controlled. The present invention further relates to a cutting insert and a method for preventing rotation of the cutting insert about its center axis in a holder for chip forming machining.

Abstract: The present invention relates to a shank (30; 60) for a milling tool, preferably an end mill, said shank (30; 60) including a first position (31; 61) and a second portion (32; 62), said first portion (31; 61) having at least a first recess (34; 64). The invention also relates to a coupling arrangement for the connection of a shank (30; 60) to a chuck (40; 50; 70; 80). When prior art shanks for milling tools are coupled to a chuck then the stability achieved in such a connection is not satisfying. The aim of the present invention is to increase the stability and consequently the load that the shank is subjected to. The present invention is characterized by having a transition surface (33; 63) between the first (31; 61) and the second (32; 62) portion, said first portion (31; 61) having a smaller diameter than the second portion (32; 62), said transition surface (33; 63) having an extension transverse to the longitudinal extension of the shank (30; 60). When coupled to a chuck (40; 50; 70; 80) the transition surface (33; 63) of the shank (30; 60) will cooperate with a contact surface (47; 57; 75; 85) of the chuck (40; 50; 70; 80).
