Pull studs

Pull studs (also called retention knobs) are the link between the drawbar of the machine and the holder.

The superior material, hardening quality and precision machining of the KEMMLER pull studs guarantee precise positioning and safe locking of the holder in the spindle.

Most machines require a standard pull stud design (DIN, ISO, BT, CAT), but some require a specific design.
Specific pull studs are available on request.
