Manual 2-jaw self-centering scroll chuck for synchronized two-jaw clamping.
2-Jaw Self-Centering Chuck
KORRETTO 2-Jaw Self-Centering Chuck is a manual lathe chuck with synchronized two-jaw movement. As a self-centering scroll chuck, it is used for workpieces that require two opposite clamping points, quick centering and flexible manual setup.

Product Overview
The 2-jaw self-centering chuck moves both jaws together toward the center. As a manual scroll chuck, the internal scroll mechanism supports synchronized two-point clamping for selected workpiece shapes where two-jaw clamping is preferred over three-jaw or four-jaw arrangements.
Selection should confirm chuck size, mounting interface, jaw configuration, workpiece shape, clamping range, required centering accuracy and machine compatibility.

FAQ
What is a 2-jaw self-centering chuck used for?
It is used for workpieces that need synchronized two-jaw clamping and quick centering.
Is this also a scroll chuck?
Yes. When the chuck uses an internal scroll mechanism to move both jaws together, it can also be described as a self-centering scroll chuck.
When should I choose a 2-jaw chuck instead of a 3-jaw chuck?
Choose a 2-jaw chuck when the workpiece shape or fixture plan works better with two opposite clamping points.
Is this a hydraulic or pneumatic chuck?
No. This is a manual chuck. Hydraulic and pneumatic chucks are separate product lines.
What should be checked before ordering?
Check chuck size, mounting interface, workpiece shape, clamping range, jaw configuration and machine compatibility.
Can it be used for all irregular parts?
Not always. Some irregular parts may require independent jaws or a custom fixture. Selection should be based on the workpiece drawing.
