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.
Thank you for helping me understand.
I see it drill, but I do not see it threadmill.
Hello Randall,
This video does not show the tool performing a threading operation just drilling.
