Supporting jaw components for compatible air or hydraulic collet chuck systems.
Air / Hydraulic Collet Chuck Jaws
KORRETTO air / hydraulic collet chuck jaws are replacement or matching jaw components used with compatible collet chuck systems. This page covers the jaws as supporting parts, not a complete collet chuck assembly. Selection should confirm chuck model, jaw interface, mounting pattern, clamping diameter, workpiece profile and actuation type.

Product Overview
Collet chuck jaws are used when the collet chuck system requires matching or replacement jaw components. They must be selected according to the chuck model and jaw interface. Using a similar-looking jaw without confirming the interface may lead to poor clamping, misalignment or unsafe operation.
This page should remain separate from complete air / hydraulic collet chuck pages.

FAQ
Are these complete collet chucks?
No. This page covers collet chuck jaws as supporting components for compatible air or hydraulic collet chuck systems.
How should I select the correct jaws?
Confirm the chuck model, jaw interface, mounting hole pattern, workpiece diameter and clamping surface before selection.
Can these jaws be used on any collet chuck?
No. They must match the specific chuck model and interface.
What information is needed for selection?
Provide the chuck model, jaw drawing if available, workpiece drawing, clamping diameter, mounting pattern and actuation type.
Can the jaw profile be customized?
In many cases the contact area can be matched to the workpiece, but the interface and base dimensions must remain compatible with the chuck.
