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 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.
