Abbott Workholding TG15HDASQ Soft Lathe Chuck Jaw Tongue Groove

Product Description

The ABBOTT WORKHOLDING PRODUCTS TG15HDASQ is a soft lathe chuck jaw with a tongue and groove interface, machined from 6061-T6 aluminum. It is designed for use in CNC and manual lathe operations where the jaw face must be bored to a specific workpiece diameter after installation. The jaw measures 6.5 inches overall length, 3 inches overall height, and 2.5 inches overall width. The tongue width is 0.75 inches and the groove width is 0.5 inches, with mount hole centers spaced 3 inches apart. Machinists and CNC setup technicians install these jaws when gripping soft, finished, or irregular workpieces that require a custom-bored grip surface.

This jaw is suited for production and job-shop lathe work in both manual and CNC turning centers. The tongue and groove interface provides positive radial and axial location on compatible chuck bodies. It is sold as a set of 3 jaws, matching standard 3-jaw chuck configurations. Compatible chuck diameters range from 15 inches to 18 inches. Typical applications include holding precision-turned parts, thin-walled tubing, castings, or any workpiece where standard hard jaws risk distortion or surface damage.

Compatibility

Compatible with 3-jaw lathe chucks having a tongue and groove interface, with chuck diameters ranging from 15 inches to 18 inches and a groove width of 0.5 inches.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Disengage and lock out all power to the lathe spindle before removing or installing chuck jaws. Seat jaws fully into the tongue and groove slots and verify all fasteners are torqued evenly before spinning the chuck. After installation, bore jaw faces in-place on the lathe at the intended gripping diameter to ensure concentricity before placing workpieces in production.
