Zusammenfassung:	To provide a piercing machine which can prevent chips from entering the piercing machine when a lower surface of a pipe is pierced.SOLUTION: When a lower surface of a pipe P is pierced by using a piercing machine 1 of the invention, a blade of a cutter 17 digs into the pipe P to generate chips C. The generated chips C fall due to its self-weight and are accumulated in a housing recessed part 14a of a dust seal 14 provided at a movement stop part 10. The structure can prevent the chips C from entering the piercing machine 1.SELECTED DRAWING: Figure 5 【課題】配管の下面を穿孔したときに、穿孔機の中に切粉が入り込んでしまうことを防止することが可能な穿孔機を提供する。【解決手段】本発明における穿孔機１を用いて配管Ｐの下面を穿孔したときに、カッター１７の刃が食い込んで切粉Ｃが発生する。そして、この発生した切粉Ｃは自重により落下し、移動振止部１０に設けられているダストシール１４の収納凹部１４ａに溜まることとなる。これにより、切粉Ｃが穿孔機１の中に侵入してしまうことを防止することができる。【選択図】図５
