Abbott Workholding Products TG12MDS1 Soft Lathe Chuck Jaw

Product Description

The ABBOTT WORKHOLDING PRODUCTS TG12MDS1 is a soft lathe chuck jaw designed for tongue and groove chuck interfaces. Machined from 1018 steel, this square-profile jaw mounts on chucks up to 12 inches in diameter and is sold as a set of three. The jaw measures 5.5 inches overall length, 3 inches overall height, and 2 inches overall width. With a tongue width of 0.75 inches and a groove width of 0.5 inches, it mates precisely to compatible tongue and groove chuck bodies. The mount hole centers are spaced 2.5 inches apart, accepting 0.5-inch fasteners. Machinists and tool room operators use these soft jaws when a job requires custom-bored or contoured gripping surfaces.

This jaw set is suited for manual and CNC lathe applications where repeatable workholding and jaw reboring are required. The 1018 steel construction provides a machinable base that can be bored, faced, or profiled to grip irregular, delicate, or finished workpieces without marring. Typical use cases include turning operations on production lathes in job shops, manufacturing cells, and maintenance machine shops. The three-jaw configuration is standard for self-centering chuck setups on lathes with 12-inch chuck capacity.
