Abbott Workholding Products TG12MDP Soft Lathe Chuck Jaw

Product Description

The ABBOTT WORKHOLDING PRODUCTS TG12MDP is a soft lathe chuck jaw designed with a tongue and groove interface for secure, repeatable seating in compatible 3-jaw lathe chucks. Machined from 6061 aluminum, this jaw measures 12 inches in overall width and 2 inches in overall height, keeping rotational mass low while maintaining rigidity during turning operations. The tongue and groove design allows the jaw to be bored in place by the machinist, enabling precise custom gripping profiles for workpiece-specific setups. This part is sold as a set of three jaws and is intended for installation by machinists and CNC lathe operators in production and job-shop environments.

This jaw is suited for use on 12-inch lathe chucks in both manual and CNC turning applications. The round jaw shape and aluminum construction make it a practical choice for light to medium-duty workholding where frequent reboring is expected. The tongue and groove mounting interface, with a 0.75-inch tongue width and 2.5-inch center-to-center mount hole spacing, is common across several chuck platforms in this diameter class. Typical applications include holding round or irregular workpieces that require a bored-to-fit grip surface.

Installation Notes

Installation should be performed by a qualified machinist familiar with lathe chuck service. Power down and lockout the lathe spindle drive before removing or installing chuck jaws. After mounting, jaws must be bored in place at the intended grip diameter to achieve concentricity. Verify fastener torque against the chuck manufacturer specifications before returning the machine to service.
