technical information about collets

Collets as clamping elements for workpieces and tools

Collets are clamping tools to clamp cylindrical workpieces or tools quickly and safely with highest accuracy on a machine tool.

Collets on pressure

With a pressure collet, the collet is pressed against the front stop nut by a pressure sleeve.

Feed Fingers

The feed fingers are used to feeding the bar material in single-spindle automatic lathes. Whether an internal or external feed collet is required depends on the desired clamping diameter.

Draw-in collets

The draw-in collet is clamped from behind with a collet wrench. The pulling collets according to DIN 6343 are used in the most different areas. They are used in toolmaking, production and testing machines.
