求教：這個孔是如何翻出來？ 如圖

A Tee extractor is used to make branching connections on installed soft copper, hard copper, and aluminum pipe. This can be faster and easier than cutting the pipe to install a T-fitting, especially in hard to reach areas.
To make a Tee in an existing pipe, drill a hole in the pipe with the supplied self-centering bit. Insert the correct-sized extractor into the hole and twist the bell until it makes firm contact with the pipe. Turn the extractor to the left with the supplied ratchet to make the flare, and use the cam pincer make a ridge on the mating pipe to set the correct insert depth. Finally, mate the pipes and solder.
0 T  u4 a/ z+ b  z4 Q  N The set comes with 1/2″, 5/8″, 7/8″, and 1-1/8″ extractors, self-centering drill bit, cam pincer, and ratchet all in a handy steel carrying case. You’ll pay somewhere in the neighborhood of $700 for this set.

終于在網(wǎng)上找到這個工具了，但真的不知道如何用

鉆孔，孔大小與翻邊高度和翻邊后的孔有關系，把旋轉頭通過鉆的底孔放入，再裝旋上內(nèi)外套，轉動扳手使旋轉頭是往外的方向...。

LZ找的專用工具圖片看不到，但據(jù)我了解像你這種薄壁等徑三通管用熱熔鉆工藝應該是達不到，而且要理解熱熔鉆的使用場合，熱熔鉆一般是為了解決管類型材壁上攻螺紋增加螺牙數(shù)加強螺紋連接強度用的。是否可以考慮模具？脹型、懸臂翻邊都是挺常見的。

這個模具可以翻管徑稍微大一點，靠近管口的的側孔。

小弟我好像在一個叫how it made的國外科普節(jié)目上看過，像是脹型法但是又好像不是。我去看看，嘻嘻
