Tool system (1) comprising a tool holder (2) that includes an insert seat (17) for accommodating an insert (6) having a depression (7), further comprising a clamping element (4) that has an opening (26) for accommodating a clamping means (15), and a projection (5), and comprising a mechanism (functional dimension (Fx) that limits the linear mobility of the clamping element (4). This ensures that a disposable insert (6) can be repeatedly securely clamped.

A cutting tool for radial and axial recessing and for lateral motion for so-called grooving of primarily metallic materials, having a clamping holder and a cutting element base, fastened to the clamping holder, on which a cutting element rests, the cutting element being pressed onto the cutting element base by a clamping finger of a clamping claw, and the cutting element being guided on the cutting element base with a prism.

A machining tool for cutting a work component includes a cutting tool insert having a cutting surface along a portion of an external surface that defines a circumference of the cutting tool insert. A plurality of cartridges are insertable into the machining tool, each having an insert pocket for receiving the cutting tool insert. The cutting tool insert is rotatable between first, second and third fixed positions in each insert pocket of the plurality of cartridges, a first portion of the cutting surface exposed when the cutting tool insert is in the first fixed position, a second portion of the cutting surface exposed when the cutting tool insert is in the second fixed position, and a third portion of the cutting surface exposed when the cutting tool insert is in the third fixed position. The insert pocket of each of the plurality of cartridges is offset from each other.

The invention relates to a cutting tool, in particular a rotating machining tool, comprising a support member, a cutting element that is releasably clamped to the support member, and a clamping jaw which is located on the support member, can be secured by means of a clamping screw and clamps the cutting element against the support member. According to the invention, a lifting element is provided between the support member and the clamping claw; when the clamping screw is unscrewed, said lifting element lifts the clamping jaw off the cutting element located on the support member.

A cutting insert including a body having three vertices, an upper face, a lower face, and flank faces joining the upper and lower faces. At least one cutting edge is formed at an intersection between the upper face and the flank faces. A generally triangular-shaped island surrounds a central axis of the cutting insert and is higher in elevation than at least one portion of the upper face.

The invention relates to a carrier tool (1) comprising a clamping element (2) with a clamping element projection (3) and comprising a cutting insert (4) with a clamping recess (5) on the cutting insert surface (13) for machining workpieces. The clamping recess (5) has an annular indentation (9) with a recess base (7), and the indentation (9) transitions from the recess base (7) into the cutting insert surface (13) via an annular surface (8). The indentation (9) surrounds an elevation (10), the tip (11) of which lies above the recess base (7) and below the cutting insert surface (13). The clamping element projection (3) engages into the clamping recess (5) and thus clamps same on the carrier tool (1). In order to allow a pre-centering of the contour of the clamping element projection (3) and the contour of the clamping recess (5) when closing the clamping element (2), the contours of the clamping element projection and the clamping recess thus engaging into each other in a form-fitting and precisely positioned manner, the clamping element projection (3) has an annular contour (12) which surrounds the elevation (10) in the clamped state but does not contact the elevation and rests solely on the annular surface (8).

A cutting tool includes a two-way indexable cutting insert retained in a tool holder by a clamping member. The cutting insert has a tetrahedral basic shape and includes two cutting edges at opposite ends of thereof. The insert holder includes a forwardly located mounting portion that includes three spaced apart mounting jaws which together define an insert receiving pocket having a pocket opening. The clamping member is attached to the insert holder body so that a clamping portion of the clamping member protrudes into the pocket opening. When the cutting insert is releasably attached to the insert holder in a fastened position of a cutting tool, the cutting insert is located in the insert receiving pocket and clampingly engaged therein by the clamping portion.

A cutting insert includes a body having three vertices, an upper face, a lower face, and six planar flank faces perpendicular to and joining the upper and lower faces. A cutting edge is formed at an intersection between the upper and lower faces and each of the planar flank faces. A triangular-shaped island surrounds a central axis, A, of the cutting insert and is higher in elevation than the upper and lower faces. A tool holder includes a tool holder body having a generally triangular-shaped insert-receiving pocket with a triangular-shaped recess that is substantially identical in shape to the triangular-shaped island of the cutting insert that interacts with the island to properly locate and prevent rotation of the cutting insert when mounted in the tool holder.

A tool assembly for heavy duty machining includes an insert, tool and clamp for securing the insert to a rigid insert seat of the tool. The insert is a solid cutting insert including a single cutting edge located at a corner region thereof. At a diagonally opposed corner region the insert is not subjected to clamping forces.
