Abstract: A replaceable face-milling head configured for rotating about a central rotation axis AR. The head includes a cutting portion and an integrally formed threaded shank-connector portion, the latter of which being configured for connecting to a shank. A length-diameter ratio LDR, defined as a cutting portion length LC divided by a cutting portion diameter DE, fulfills the condition: LDR?1.00.

Abstract: A cutting insert for use in a cutting tool has upper, lower and side surfaces and at least one cutting edge formed at an intersection of the upper surface with the side surface thereof. A rake face of the insert is formed with an undulated chip forming groove extending along the cutting edge and comprising a succession of alternating depressed and raised portions. Each raised portion of the chip forming groove is formed with a truncated top portion of a width which is substantially less than a distance between two adjacent truncated top portions. The depressed and raised portions preferably extend, in the direction perpendicular to the cutting edge, along the entire width of the chip forming groove.

Abstract: A metal cutting tool having a metal cutting tip such as a replaceable insert, having top and bottom faces and a plurality of peripheral faces and a rake face forming part of the top face. A cutting edge is formed at the intersection of the top face and one of the peripheral faces. Chip forming means is formed on the top face and comprises, in lateral sectional view, successive portions of which at least one is relatively recessed with respect to a preceding or succeeding portion. A through-going bore is formed in the insert and extends from one of the bottom and peripheral faces to the relatively recessed portion in a direction towards the cutting edge.
