    Abstract: PROBLEM TO BE SOLVED: To prevent a plastic deformation of a fastener for a tool by providing a stopper for the fastener. SOLUTION: A tool 10 has a holder 11 having a cutting insert recess 12. The holder 11 has an inclined surface provided at a distance from the cutting insert recess 12. The inclined surface is inclined in the direction downward from the cutting insert recess 12. The holder 11 has a screw hole for fastening a faster. A cutting insert 21 is provided on the cutting insert recess 12, having an upper surface 22 at least a part of which is flat. A fastening means 25 for operating in cooperation with a fastener hole 37 and a hole is provided so as to push the cutting insert 21 toward inside in the above direction in attaching the cutting insert 21. The fastener and the holder 11 have a spring and/or a stopper surface provided against the fasteners movement direction.

    Abstract: The present invention relates to an indexable milling insert (1) having triangular shape, the cutting insert (1) comprising a mounting hole (7) placed centrally in the cutting insert, a first support surface (3) and a second support surface (5), which support surfaces (3, 5) are parallel with each other and act as alternating support surfaces, that the cutting insert (1) comprises three equally long sides (S1, S2, S3), which extend between the parallel support surfaces (3, 5), that the cutting insert (1) is provided with main cutting edges (H1-H6), which are orientated perpendicularly to the centre axis (9) of the mounting hole (7) as well as provided in such a way that a rotation of the cutting insert (1) around the centre of the mounting hole (7) to an alternative insert seat alternatively a turning of the cutting insert (1) to an alternative insert seat provides an identical location of the main cutting edges (H1-H6) in relation to a piece to be machined. The invention also relates to a milling tool equipped with the milling inserts (1) defined above. Characteristic of the milling insert according to the present invention is that the cutting insert (1) comprises planar support surfaces (11-13) situated on the sides (S1-S3), that the support surfaces (11-13) in the respective sides (S1-S3) form mutual angles of 60° and that each one of the minor cutting edges (B1-B6) has a chamfer (10), the width of the chamfer (10) of the minor cutting edge (B1) extending transversely to the corresponding width of the chamfer of an adjacent minor cutting edge (B2).
