Type C camlock-style 4-jaw independent chuck for flexible manual lathe setups.
4-Jaw Independent Chuck, Type C
KORRETTO 4-Jaw Independent Chuck Type C combines four independently adjustable jaws with a camlock-style mounting interface. It is selected for manual lathe setups where irregular workpieces, non-round shapes or offset adjustment require individual jaw control.
Product Overview
The Type C 4-jaw independent chuck is used when the machine spindle uses a camlock-style interface and the workpiece requires independent jaw positioning. Each jaw can be adjusted separately to locate square, rectangular, cast or eccentric parts.
Selection should confirm the chuck size, camlock spindle nose, mounting dimensions, workpiece shape, clamping range, adjustment requirement and machine compatibility.

FAQ
What is a Type C 4-jaw independent chuck?
It is a 4-jaw independent manual chuck with a Type C camlock-style mounting interface.
Is this a self-centering chuck?
No. The jaws are adjusted independently. Use a self-centering chuck when synchronized jaw movement is required.
When should I choose a camlock-style Type C chuck?
Choose it when the lathe spindle and mounting system require a Type C camlock-style interface.
Can it hold square or irregular workpieces?
Yes. Independent jaw adjustment makes it suitable for many square, rectangular, cast or irregular parts.
What should be checked before ordering?
Check chuck size, spindle nose type, mounting dimensions, workpiece shape, clamping range and required adjustment accuracy.
Is it suitable for high-volume quick loading?
It is mainly used where flexible individual jaw setting is needed. For quick repeated loading, a self-centering or power chuck may be more suitable.
