Heavy-duty 4-jaw manual chuck for larger and heavier workpieces.
4-Jaw Heavy-Duty Chuck
KORRETTO 4-Jaw Heavy-Duty Chuck is designed for manual lathe workholding where larger, heavier or more demanding workpieces require stronger chuck construction and stable clamping support.
Product Overview
The 4-jaw heavy-duty chuck is selected when a standard chuck is not suitable for the workpiece size, weight or machining load. It supports robust manual setup for large castings, forgings, heavy components and demanding turning operations.
Selection should confirm chuck size, machine capacity, mounting interface, workpiece weight, clamping range, jaw configuration and required machining load.

FAQ
What is a heavy-duty chuck used for?
It is used for larger, heavier or more demanding workpieces that require stronger chuck construction and stable support.
Is this the same as an extra-large chuck?
Not exactly. A heavy-duty chuck focuses on stronger construction and robust clamping support, while extra-large chuck selection is based mainly on larger size requirements.
What should be checked before choosing this chuck?
Check chuck size, machine capacity, mounting interface, workpiece weight, clamping range and machining load.
Is it suitable for small precision parts?
It is mainly selected for heavier or more demanding workpieces. Smaller precision parts may require a different chuck type.
Is this a hydraulic chuck?
No. This is a manual heavy-duty chuck. Hydraulic chucks are separate product lines.
What information should I provide?
Provide machine model, spindle interface, chuck size, workpiece weight, workpiece drawing and machining requirement.
