    Please help me understand how it can tap the thread and then withdraw without changing the direction of rotation? It is a fantastic tool that obviously saves much.

      Hello Frank,

      This video is only showing the tool performing a drilling operation. This tool saves time by not forcing you to make a tool change. First, you would drill the hole, then go back in with this same tool and helically interpolate the threads.
