Range of Driven Tools Increases Accuracy
The retention knob is an unmistakably critical component of the machining process. However, the tightening of the knob itself can lead to the toolholder not seating securely in the machine. You may be losing tool life to knob tightness without even knowing it.
I’ve said that the toolholder is the least appreciated element in many milling processes, but the pull stud (or retention knob) is perhaps the least appreciated component of the toolholder.
Far from being outdated by the latest machine tool technology, angle heads often prove an ideal complement by pushing done-in-one capabilities even further. Proper application, however, requires attention to their limitations as well as their benefits.
