In CNC machining, the tool holder, collet, and pull stud must work in precise coordination to achieve optimal tool performance. A deficiency in any of these components can lead to decreased accuracy, increased vibration, and shortened tool life. This article will explain how these three components work together and provide overall selection recommendations.
