Abbott Workholding Products KTT6S Soft Lathe Chuck Jaw Serrated

Product Description

The ABBOTT WORKHOLDING PRODUCTS KTT6S is a serrated soft lathe chuck jaw machined from 1018 steel for use in manual and CNC lathe setups. Soft jaws are designed to be bored or machined in-place by the operator, allowing a custom fit to the workpiece and reducing runout. This jaw measures 3 inches in overall length and 1.25 inches in overall width, with a mount hole center spacing of 0.7874 inches and a fastener size of 0.3937 inches. It is sold and installed as a set of three jaws and is compatible with chucks up to 6 inches in diameter. Machinists and toolroom technicians are the primary installers.

The KTT6S is suited for general turning operations on manual lathes and CNC turning centers where repeatable workholding and part-specific jaw profiles are required. Serrated jaw interfaces provide positive engagement with the chuck body, resisting jaw shift under cutting loads. This jaw is appropriate for both prototype and production environments where soft jaws are re-bored for multiple part runs. The square jaw shape and standardized mounting dimensions make it a straightforward replacement in setups already configured for this jaw style.

Key Features

• Serrated jaw interface for positive, shift-resistant engagement with the chuck body
• 1018 steel construction allows field machining and re-boring to match workpiece geometry
• 3 inches overall length provides material for multiple re-bore cycles over the jaw lifespan
• Slot width of 0.472 inches and groove width of 0.4724 inches suit standard chuck body configurations
• Sold as a set of three jaws for balanced three-jaw chuck installation

Compatibility

Designed for use with three-jaw lathe chucks up to 6 inches in maximum compatible chuck diameter with serrated jaw interfaces, 0.7874-inch mount hole center spacing, and 0.3937-inch fastener size.

Installation Notes

Soft lathe chuck jaws are typically installed and bored by a machinist or toolroom technician. Before removing or installing chuck jaws, power down the lathe, engage the spindle lock, and confirm the chuck is fully stopped. Secure all three jaws evenly and verify fastener engagement before boring. Always bore soft jaws in the chuck in which they will be used to minimize runout.
