Thread i.e. internal thread, creating tool for workpiece, has thread creating area and brush area provided with set of bristles, where two areas are coupled or connected with each other such that two areas are rotatable about tool axis

摘要

The tool (2) has a thread creating area e.g. thread drilling area (4), and a brush area (3) with a set of bristles (30), where the thread creating area and the brush area are coupled or connected with each other such that the areas are rotatable about a tool axis (A). The bristles of the brush area are partially formed of a metallic material e.g. steel or brass or polymer material. The thread creating area and the brush area are arranged one after the other axial to the tool axis, or in a circumferential direction about the tool axis.
