Abstract: An indexable milling insert includes opposite top and bottom sides between which a peripheral clearance surface extends, and two opposite cutting edges formed in the transition between the top side and the clearance surface. Each of the cutting edges includes a substantially straight portion connected with a straight section of the clearance surface, and further includes a curved portion connected with a convexly arched section of the clearance surface. A coupling including one or more male- and/or female-like engagement members is located along said clearance surface. Furthermore, the milling insert may be used with a shim plate for attachment to a milling tool.

Abstract: A cutting tool, and a loose top therefore, includes two parts detachably connected to each other via a threaded joint in which co-operating male and female threads are included in the form of helicoidal ridges. The profile shape of each helicoidal ridge is defined by a top and two flanks, which delimit a helicoidal groove having a bottom. The first flank is inclined in relation to a center axis of the tool at a first angle that is smaller than a second angle of the second flank in relation to the center axis. Accordingly, the thread ridge is reinforced in comparison with thread ridges having a symmetrical profile shape, whereby larger tensile forces than compressive forces can be applied to the threaded joint while avoiding damage to the thread ridges.

Abstract: A milling cutter head in the form of a body, which has an external envelope surface having a rotationally symmetrical basic shape in respect of a central axis, and includes a plurality of peripherally spaced-apart cutting edges and chip flutes. The cutter head includes two axially spaced-apart ends in which hollow spaces open, which are arranged to receive male elements included in a basic body, and are spaced-apart by a partition wall in which a through hole is formed. The through hole mouths in bottom surfaces in the hollow spaces. The cross-section area of each individual hollow space, in a plane perpendicular to the center axis, amounts to at least 25% of the total cross-section area of the body, as defined by the greatest diameter of the envelope surface.

Abstract: A replaceable milling cutter head, which has an external envelope surface having a rotationally symmetrical basic shape in respect of a central axis. The cutter head includes a plurality of peripherally spaced-apart cutting edges and chip flutes, and two axially spaced-apart, front and rear ends. An axial hole extends all the way through a frame of the cutter head. The milling cutter head has a flat, pulley-like basic shape, such that the axial distance between the two ends thereof is at most half as large as the greatest outer diameter thereof. A hollow space for receiving a male element of a basic body is recessed in the rear end of the milling cutter head. The cross-section area of the hollow space, in a plane perpendicular to the center axis, amounts to at least 25% of the total cross-section area of the milling cutter head, as determined by the outer diameter.

Abstract: A rotatable cutting tool for chip-removing machining includes a basic body which defines a center axis of rotation. Cutting inserts are detachably mounted in respective cutting seats that are formed in the basic body. Each insert has a square shape and includes first and second pairs of mutually parallel major cutting edges, four corners, and four wiper edges. Each wiper edge is situated between a major cutting edge and a respective corner. The wiper edges are shorter than the major cutting edges and are inclined relative thereto, wherein an imaginary extension line of the wiper edge forms a first acute angle with the respective major cutting edge as the insert is viewed in a direction perpendicular to the top surface. The cutting seats are arranged to orient the inserts wherein an axially forwardmost wiper edge of each insert lies in a plane oriented perpendicular to the axis, and wherein a radially outermost wiper edge of each insert is oriented parallel to the axis.
