Abstract: A cutting insert (10) is adapted to be clamped against a tool body (14) through a first side surface (12). Grooves (21) are provided in a second side surface (11) opposed to said first side surface for providing a serrated cutting edge (16). The grooves (21) are designed such that inclination of the cutting inserts is made possible.

Abstract: The present invention relates to a cutting tool for milling, boring or turning, comprising a holder shank (10) with a slotted end and a blade (13) clamped in the slotted end of the holder shank (10) by means of a clamping screw (16) which loosely extends through the blade (13). The blade (13) is provided with a recess (22) having radially displaced abutment surfaces (24A,24B) that are to abut outer edges (21A,21B) of the slot so as to radially center blade (13) in the slot (17) when tightening the screw (16). Furthermore, the invention relates to a blade (13) for use in connection with the above-mentioned holder shank (10).

Abstract: A cutting insert for a cutting tool includes a cutting edge having a concave portion and a rear portion. The concave portion is disposed in the plane of one side surface of the insert and engages a workpiece in advance of the rear portion of the cutting edge. The latter extends from a radially outer end of the convex portion and has components directed radially outwardly, longitudinally rearwardly and toward the opposite side surface of the insert. The rear portion sequentially engages the workpiece to reduce the amount of vibration of the tool.
