Question

Quizplus · Accepted Answer

Step collets have a stepped design that allows them to grip on short workpieces that have larger diameters than what can fit within the standard spring collets. The stepped design also provides more contact area with the workpiece for increased gripping power. Spring collets are not suitable for gripping on larger diameter workpieces that exceed their gripping range. Drive collets are typically used in CNC machines for quick and easy tool changes, and flex collets are designed to hold on to the workpiece with more flexibility, which is not necessary for short workpieces with larger diameters.
