Spanntechnik OP3 | CS311 - Extension Collet Chuck

The extension collet chuck represents the basic clamping system for drilling machines. The wheel is clamped by using an expanding collet in the hub hole in order to grant the correct wheel positioning.
The chuck body accepts wheels from 13" to 24". In case of wheel model changes, only the central collet and the wheel support ring, which are designed for each wheel size, need to be changed.
