Abstract:
PROBLEM TO BE SOLVED: To provide a tool of a type oriented along a common central axis and including two parts detachably coupled with each other by a screw joint, parts thereof, and a screw joint. SOLUTION: A cutting tool, and a loose top therefor include two parts detachably coupled with each other by a screw joint, and the screw joint includes a male screw 10 and a female screw cooperating with each other in a form of helical threads 10. A profile and shape of the respective helical thread 10 are defined by two flanks 22, 23 defining a helical groove part having a peak 21 and a bottom 25. The first flank 22 is inclined at a first angle α relative to a central axis of the tool, and the first angle α is smaller than a second angle β of the second flank relative to the central axis. Accordingly, compared to the thread having a symmetrical profile and shape, the thread 10 is reinforced, and a tensile force larger than a compression force can be applied to the screw joint, so as to also avoid damage to the thread 10.
