本考案は斜面に穿孔された穴の端部を面取り加
工する工具に関するものである。[Detailed Description of the Invention] The present invention relates to a tool for chamfering the end of a hole drilled in a slope.
工作機械の主軸に対して傾斜した面に加工され
た穴の面取り加工を行う場合、従来は第１図に示

ンダによる手仕上等別工程により加工する必要が
あり、作業能率の低下等の不具合があつた。 When chamfering a hole machined on a surface inclined with respect to the main axis of a machine tool, conventionally, as shown in Fig. 1, drilling is performed on the slope of the workpiece W while rotating a cutting tool B formed into a chamfered shape. Since the chamfering process is carried out in the direction of the center line of the hole, only the upper part of the slope can be chamfered incompletely. Therefore, it is necessary to process the chamfer in a separate process such as manual finishing with a grinder, which reduces work efficiency. There was a problem.
