Abbott Workholding KTT10A3 Soft Lathe Chuck Jaw Serrated

Product Description

The ABBOTT WORKHOLDING PRODUCTS KTT10A3 is a serrated soft lathe chuck jaw machined from 6061-T6 aluminum. Soft jaws are re-machinable to a specific bore or contour, allowing a lathe operator to hold irregular, finished, or delicate workpieces without damage. This jaw measures 2.0 inches overall width, 3.0 inches overall height, and 5.5 inches overall length. The serrated interface mates to standard serrated chuck jaw slides, providing positive registration and repeatable positioning. The 6061-T6 aluminum construction keeps rotating mass low while delivering enough hardness for light to medium turning operations. Licensed machinists and CNC lathe operators are the primary installers and users of this component.

This soft jaw is designed for use on lathes equipped with a 3-jaw chuck rated for up to 10.0 inches maximum chuck diameter. The serrated jaw interface and 0.4724-inch fastener size are matched to chucks with a 1.1811-inch distance between mount hole centers and a 0.6300-inch slot width. Typical applications include precision part holding on manual engine lathes and CNC turning centers in job shop, production machining, and toolroom environments. A set of 3 jaws is required for a complete installation, and this listing covers a single jaw.

Compatibility

Designed for use with serrated 3-jaw lathe chucks with a maximum compatible chuck diameter of 10.0 inches, a mount hole center distance of 1.1811 inches, and a slot width of 0.6300 inches. Verify chuck jaw interface specifications before ordering.

Installation Notes

Soft jaws are installed and bored in-place by a qualified machinist or CNC lathe operator. Before removing or installing chuck jaws, power down the lathe and confirm the spindle has come to a complete stop. Use the correct fastener size as specified by the chuck manufacturer and torque jaw bolts evenly to prevent jaw distortion. Soft jaws must be bored to the required diameter while mounted in the chuck to ensure concentricity - never pre-machine a bore offline and expect it to run true after installation.
