Value Collection 193269.00 Soft Lathe Chuck Jaw Jf Steel

Product Description

The VALUE COLLECTION 193269.00 is a round soft lathe chuck jaw designed for use in metal turning operations on manual and CNC lathes. Soft jaws are machined to final form by the operator, allowing a custom bore or step profile that grips workpieces with precision and minimal distortion. This jaw features a JF interface type and is constructed from steel, offering durability through repeated boring and reboring cycles. The set includes 6 jaws, covering a compatible chuck diameter of 2.16 inches. Overall jaw height is approximately 9.10 millimeters. It is suited for machine shops, tool rooms, and production environments where repeatable, close-tolerance workholding is required.

This soft jaw set is intended for lathe chuck applications requiring a custom-bored grip surface. The JF interface type fits chucks in the compatible diameter range, and the round jaw shape suits cylindrical and ring-shaped workpieces. Machinists bore these jaws in place on the chuck to match the specific workpiece diameter, eliminating runout introduced by conventional hard jaws. Typical use cases include finish turning, grinding pre-work, and any operation where concentricity and part surface protection are critical priorities.

Key Features

• Round jaw shape for cylindrical and ring workpiece applications
• JF jaw interface type for correct chuck fitment
• Steel construction supports multiple reboring cycles
• 6-jaw set provides full chuck coverage for balanced clamping
• Compatible chuck diameter of 2.16 inches
• Overall jaw height of 9.10 millimeters allows adequate boring depth

Compatibility

Designed for use with lathe chucks using a JF jaw interface with a compatible chuck diameter of 2.16 inches.

Installation Notes

Soft jaw installation and boring should be performed by a qualified machinist. Before mounting or boring jaws, ensure the lathe spindle is fully powered down and locked out per shop lockout/tagout procedures. Jaws must be bored while under the same clamping load used during production to ensure concentricity. Do not exceed the chuck manufacturer's rated RPM after boring, as material removal affects jaw mass balance.
