Drilling Long parts with extensive tool holders

In this video, you will see how we manufacture long parts on a milling machine. Specifically, we are going to center drill, drill, and tap a hole. Because we needed to reach a long depth we made a tool holder 18 mm and 170 mm long to put our drill and tap and reach the distance. As you see in the video all the extensive tools revolutions are really slow because of the long length we have run out almost 0. 03 mm and it is possible to break the tool during the process that s why the revolution speed is extremely low, especially on the tapping operation.
