A cutting insert includes a cylindrical body portion, a cutting portion, a first fitting portion, a second fitting portion, and a third fitting portion. The cylindrical body portion has a first main surface, a second main surface, and an outer circumferential surface, and is provided with an insertion hole. The cutting portion protrudes from the outer circumferential surface in a radial direction. The first fitting portion, the second fitting portion, and the third fitting portion each protrude from the second main surface in an axial direction and each extend in the radial direction. The cutting portion includes a rake face and a flank face. A ridgeline between the rake face and the flank face constitutes a cutting edge. When viewed in the axial direction, the cutting portion is provided opposite to the third fitting portion relative to the insertion hole. When viewed in the axial direction, a straight line extending through an outer circumferential end of the cutting edge and a center of the insertion hole overlaps with the third fitting portion and is located between the first fitting portion and the second fitting portion. A third central angle is smaller than a first central angle and is smaller than a second central angle.

A cutting device comprising a cutting insert and a holding part with a beam part, extending in a longitudinal direction, and a clamping head, which projects beyond an upper side of the holding part with a projection, wherein the projection is connected to a first of two clamping fingers which between them form a receiving pocket for receiving the cutting insert. A clamping gap is provided underneath the projection to allow the first clamping finger to be elastically movable. The clamping gap opens out into the receiving pocket and runs from an end face of the holding part that is facing the workpiece to be worked in the longitudinal direction up to the rear end of said holding part, which rear end is arranged in the transitional region between the clamping head and the beam part. A coolant and/or lubricant guide is provided for feeding coolant and/or lubricant to a coolant and/or lubricant outlet arranged in the projection. The projection extends with a continuing portion in the longitudinal direction beyond the rear end of the clamping gap and the coolant and/or lubricant guide runs through the continuing portion.

A tool for machining a workpiece is presented. The tool has a cutting insert with at least one cutting edge, a holder having a shank, and a cutting insert receptacle, wherein the cutting insert receptacle is arranged in a region of a workpiece-side end face of the shank, and the cutting insert is disposed in the cutting insert receptacle. The holder has a coolant bore, which opens out into a plurality of coolant outlets. The plurality of coolant outlets are arranged on the workpiece-side end face of the shank, alongside the cutting insert receptacle, and are oriented such that coolant is discharged towards the cutting insert. At least some of the coolant outlets lie in a coolant outlet plane which runs parallel to and offset from a cutting insert plane running through the cutting insert receptacle, where the coolant outlet plane and the cutting insert plane run parallel to the longitudinal direction of the shank.

A cutting tool for machining a workpiece. The cutting tool comprises a holder and at least two cutting inserts which are separated from each other by a spacer element. The cutting tool may be used to produce two or more bevels (and/or joints and/or grooves) at precisely defined spacings in only one operation. Through the use of spacer elements of different lengths, it is possible to produce bevels at different spacings. The spacer element preferably has an interface which comprises only radial contact surfaces, which run parallel to a longitudinal axis of the spacer element, and a substantially flat axial contact surface, which runs transverse to the longitudinal axis. The length of the spacer element can therefore be shortened on the rear side of the spacer element without destroying said interface.

The present invention relates to an indexable insert for a tool for machining a workpiece, wherein the indexable insert (10) is 120° rotationally symmetrical about a bore axis (12), which runs vertically and centrally through two opposing end faces (20a, 20b) of the indexable insert (10). Said indexable insert has two identical sub-elements (16a, 16b) which are connected to one another, each of which has three identical main cutting tips (18a-c, 18d-f) arranged relative to one another at an angle of 60° and in one plane, which run parallel to the two opposing end faces (20a, 20b) and at an angle to the bore axis (12). The two sub-elements (16a, 16b) are formed on the one hand as mirror-inverted to one another relative to a mirror plane, which runs vertical to the bore axis (12) and which is at the same distance from the two end faces (20a, 20b), and on the other hand are additionally rotated relative to one another about the bore axis (12) by a defined rotational angle (22). The three main cutting tips (18a-c, 18d-f) of each sub-element (16a, 16b) of the indexable insert (10) are formed as cutting edges at the transition between the end face (20a, 20b) of the respective sub-element (16a, 16b) and a cutting face (38a-f) is formed transverse to the respective end face (20a, 20b). The respective cutting face (38a-f) is tilted at a defined cutting angle relative to the bore axis (12). A contact surface (40a-f) running parallel to the bore axis (12) is formed between the mirror plane and the cutting surfaces (38a-f) of each sub-element (16a, 16b). Each cutting edge (18 a-f) is rounded off at the end side at the first end (32) thereof by a corner radius (26) and which has at the second end (34) thereof lying opposite in the edge direction (30) a material incision provided with a chamfer (28).
