A tool body in which a cutting insert can be replaced easily is provided. The tool body which fixes the indexable cutting insert includes an insert mounting seat which is provided on a first surface of the tool body, a clamp member which binds the cutting insert placed on the insert mounting seat, and an operating member which operates the clamp member. The operating member can lower the clamp member from the first surface toward a second surface of the tool body on an opposite side thereof to the first surface and can raise the clamp member from the second surface toward the first surface. The clamp member has a hook portion which is brought into contact with a diameter reducing portion formed on an inner peripheral surface of a mounting hole of the cutting insert in a state where the clamp member is lowered.

A tool for chip removing machining includes a tool body having at least one insert seat that accommodates a cutting insert having a top and a bottom surface. The tool body secures the cutting insert in the insert seat by an attachment member, and the insert seat has a bottom surface and at least one side surface. The tool includes at least one assembling aid, which is provided at least at one insert seat and which includes a clamping section and a mounting section. The clamping section extends above the bottom surface of the insert seat for, when the cutting insert is accommodated in the insert seat, engaging the top surface of the cutting insert. The clamping section is biased towards the bottom surface of the insert seat and the mounting section is attached to the tool body. A kit includes the tool, a shim and the assembling aid.

A machining tool includes a tool carrier with at least one seat receiving an exchangeable, indexable cutting insert. A fastening screw fastening cutting insert to seat has a head section for support on the cutting insert and a shaft section at least regionally having an external screw thread. The seat has a contact face supporting an underside of the cutting insert and at least one lateral bearing face supporting a side surface of the cutting insert. A through-hole is formed in the contact face, through which the shaft portion of the fastening screw extends. A clamping element is disposed on the tool carrier on the rear side of the contact face of the seat, in which an internal screw thread is formed, cooperating with the external screw thread of the fastening screw. The fastening screw and the clamping element can be jointly displaced in a displacement direction.

A cutting tool assembly includes a tool shank having a coupling opening, and an insert holder having an insert body to which an insert is coupled and detachably attached. A coupling protrusion protrudes from one surface of the insert body and is detachably coupled to the tool shank. Located on the coupling protrusion are a tapered contact portion which comes into contact with the coupling opening and provides a fixing force to fix the insert holder to the tool shank, and a contact surface at a rear end of the tapered contact portion which couples to a fastening member.

A cutting insert adaptor for an insert pocket can include one or more pairs of opposing insert abutment surfaces and pocket abutment surfaces which converge at an acute angle. The one or more insert abutment surfaces are all rotated in the same direction, relative to their paired pocket abutment surface which in turn rotates a cutting insert abutting the cutting insert adaptor relative to an orientation the cutting insert would have if it only abutted the insert pocket instead of the cutting insert adaptor.

An insert adaptor is configured for providing secure clamping of an insert in an insert pocket. The insert adaptor is configured to be located between an insert and an insert pocket and includes at least one magnetic surface configured for applying a magnetic attraction force to the insert pocket or a shim.

A metal cutting tool includes a tool holder, a seat in the tool holder defined by side walls and a bottom surface. A replaceable element formed by an insert seating anvil is positioned in the seat and secured by a fastening device. A cutting insert is supported on a base surface of the anvil. The anvil has a projecting element formed integrally with the anvil. The projecting element is rigid and has a dove tail shape in top view, wherein the projecting element base and lower surfaces form coplanar extensions of the base and lower surfaces of the rest of the anvil.

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.
