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 cutting tool including a basic body having a geometrical center axis, a loose top having a rear male element, and a drawbar having a front part in which a coupling means is included, which by engagement in a coupling means of the male element of the loose top can transfer axial forces. The coupling means form an interface between the loose top and the drawbar. Each coupling means includes two axially separated ridges, a front ridge in the male element is between a front groove and a rear groove, the front groove being shallower than the rear groove such that the bottom thereof is situated at a greater radial distance from the center axis than the bottom of the rear groove.

Abstract: An indexable milling insert for milling tools, including a bottom surface, an opposite chip surface, and a plurality of side surfaces extending between the bottom surface and the opposite chip surface, two of the side surfaces being primary clearance surfaces and two of the side surfaces being secondary clearance surfaces. A plurality of cutting edges are formed between the opposite chip surface and the primary and secondary clearance surfaces. Two of the cutting edges that connect to the primary clearance surfaces are primarily parallel and constitute main cutting edges. At least one lock structure is provided and includes a locking surface arranged on one of the secondary clearance surfaces so that the locking surface and the primary clearance surface form an acute angle, α, in a section that is parallel to the bottom surface and intersects the locking surface. A coupling structure is arranged on the opposite chip surface and at least partly projects from a plane that is parallel to the bottom surface and passes through points of the main cutting edges situated closest to the bottom surface. The coupling structure comprises at least one flank surface, which is arranged in such a way that the flank surface, in a section that is parallel to the primary clearance surface and intersects the flank surface, forms an acute angle, β, with the bottom surface so that the flank surface slopes in the direction from the secondary clearance surface on which the locking surface is arranged.

Abstract: A rotatable tool includes a shank rotatable about a longitudinal axis, a drawbar mounted to an axial front end of the shank, and a cutting head mounted to an axial front end of the drawbar. The shank and the drawbar include mutually engageable screw threads which impart an axial displacement of the drawbar relative to the shank. The cutting head and the drawbar include mutually engageable serrations for transferring axial force therebetween. The serrations are axially spaced from one another and extend transversely relative to the axis.
