Abbott Workholding Products KTT6S2 Soft Lathe Chuck Jaw

Product Description

The ABBOTT WORKHOLDING PRODUCTS KTT6S2 is a soft lathe chuck jaw designed for use on 6-inch lathe chucks requiring a serrated jaw interface. Manufactured from 1018 steel, this square-profile jaw measures 3 inches in overall height, 3 inches in overall length, and 1.25 inches in overall width. The serrated interface provides positive grip engagement at the chuck body, and the soft jaw construction allows machinists to bore the jaw face to match a specific workpiece diameter. This part is installed by machinists and toolroom technicians as part of a three-jaw set.

This jaw is suited for manual and CNC lathe applications where repeatable workholding is required. It is compatible with 6-inch chucks that accept a serrated jaw interface with a 0.787-inch mount hole center distance and a 0.394-inch fastener size. The 0.472-inch slot width and 0.472-inch groove width align with standard chuck body specifications at this diameter class. It is commonly used in job shop and production environments for holding round, square, and irregular stock after the jaw face has been bored to size.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the lathe spindle before removing or installing chuck jaws. Ensure the serrated jaw interface is fully seated and fasteners are secured to the chuck manufacturer's recommended specification before operating the spindle. Bore the jaw face to the required diameter only after the jaw is fully mounted and torqued in place.
