Abbott Workholding Products KTT15B212P Soft Lathe Chuck Jaw

Product Description

The ABBOTT WORKHOLDING PRODUCTS KTT15B212P is a serrated soft lathe chuck jaw machined from 6061 aluminum, designed for use in CNC and manual lathe setups where repeatable, damage-free workholding is required. The jaw features a round jaw shape with a serrated interface that locks into compatible chuck bodies. Rated for a 12-inch maximum and minimum compatible chuck diameter, this jaw set includes 3 jaws with an overall width of 15 inches and an overall height of 3 inches. The 6061 aluminum construction keeps rotating mass low while remaining machinable for custom bore profiles. Installation is handled by machinists and lathe operators in production and job-shop environments.

This jaw set is suited for lathe applications requiring a full 12-inch chuck diameter. The serrated jaw interface provides positive engagement with the chuck body, reducing the risk of jaw shift during heavy or interrupted cuts. The 0.6299-inch fastener size and 1.1811-inch distance between mount hole centers are standard reference dimensions for fitment verification. Slot width measures 0.8270 inches and groove width measures 0.8268 inches. Typical applications include facing, turning, and boring operations on medium to large-diameter workpieces in both light production and precision machining environments.

Installation Notes

Installation is performed by qualified machinists or lathe operators. Power down and lockout the lathe spindle drive before removing or installing chuck jaws. Use the correct fastener size and torque per the chuck manufacturer's documentation - do not overtighten, as aluminum jaws can deform. Inspect the serrated interface surfaces for debris or damage before seating the jaws to ensure full engagement and safe workholding.
