The invention relates to a cutting tool with a holder, a cutting insert and a screw, wherein the holder has at least one seat with a base, a first side wall and a second side wall, wherein in a plane parallel to the base the first side wall extends in a first direction and the second side wall includes an acute angle (C) with the first side wall, wherein the base has a threaded hole for receiving the screw, wherein the cutting insert has a cut-out for the screw, wherein the cutting insert has a base contact surface, a first positioning surface and a second positioning surface, and wherein in a locked position the base contact surface, the first positioning surface and the second positioning surface of the cutting insert contact the base, the first side wall and the second side wall of the at least one seat, respectively, wherein the second side wall is offset from the threaded hole in the first direction towards a front end of the seat, and in that a screw head of the screw and the cut-out of the cutting insert are provided with complementary conical surfaces, such that when tightening the screw the cutting insert is forced with the first positioning surface and the second positioning surface against the first side wall and the second side wall, respectively.

Cutting tool for a cutting machine

A cutting insert having a first coupling structure, a tool holder having a complementary second coupling structure with a seat for a milling tool system, and a milling tool system having a cutting insert and a holder are all described. The first coupling structure has a circular cylindrical element with a cylinder abutment surface, the circular cylindrical element projecting axially from a bottom surface of a central body and being arranged concentrically with respect to a central axis, A perpendicular abutment surface is arranged perpendicular to the central axis, and at least two ribs project axially from the bottom surface. Each rib has a contact area with a normal direction at least essentially perpendicular to the central axis for opposing a torque about the central axis.

Cutting insert and a tool holder with a seat for cutting insert

A cutting tool has a tool body provided with at least one insert pocket in which a cutting insert is retained. A device for adjusting a position of the cutting insert within the insert pocket is also provided. A cavity adjacent the insert pocket accommodates an adjustment wedge having a forward surface in sliding contact with a minor side surface of the cutting insert and an adjustment screw threadingly engaged with a female threaded section of the adjustment wedge. The adjustment screw is constrained to remain in its position in the cavity, although rotation of the adjustment screw about its axis results in a sliding motion of the adjustment wedge relative to the cavity and a sliding motion of the forward surface relative to the minor side surface, which translates to displacement of the cutting insert in a direction parallel to a base surface of the insert pocket.

Cutting tool having an adjustment mechanism

A cutting tool includes at least one cutting portion, having an insert pocket, releasably retaining a single-sided cutting insert therein. The cutting portion has a tangential screwing element to clamp the cutting insert in the insert pocket. The screwing element, which comprises a screw, allows releasing and clamping of the cutting insert without having to completely remove the screwing element from the insert pocket. The cutting insert has a top surface, a bottom surface and a peripheral side surface; a recess is formed in the bottom surface. The screwing element is inserted into the recess via the bottom surface. Upon fastening of the screw, a protruding portion of the screwing element clamps the cutting insert in its insert pocket. The cutting insert and protruding portion may have respective geometries allowing them to abut one another at at least two distinct abutment sub-regions.
