Abbott Workholding TG15HDS5 Soft Lathe Chuck Jaw Tongue Groove

Product Description

The ABBOTT WORKHOLDING PRODUCTS TG15HDS5 is a soft lathe chuck jaw with a tongue and groove interface, designed for precision workholding on metal lathes. Machined from 1018 steel, this square-profile jaw measures 2.5 inches in overall width, 5 inches in overall height, and 6.5 inches in overall length. The tongue and groove design provides a secure, repeatable seating connection to compatible chuck bodies. Soft jaws allow machinists and lathe operators to bore or machine the jaw face to a custom profile, making them the standard choice when gripping finished, delicate, or irregularly shaped workpieces without marring the surface.

This jaw is suited for production and job-shop lathe operations where a 3-jaw chuck configuration is in use. It is compatible with chuck bodies ranging from 15 inches to 18 inches in diameter. The 3-inch center-to-center mount hole spacing and 0.75-inch tongue width are the primary fitment dimensions that must match the chuck body before ordering. Typical applications include turning operations on CNC and manual lathes in metalworking shops, tool rooms, and production machining environments.

Installation Notes

Installation should be performed by a qualified machinist or lathe operator. Disengage and lock out the lathe spindle before removing or installing chuck jaws. Confirm that tongue width, groove width, and mount hole spacing match the chuck body exactly before seating the jaws. Soft jaws must be bored or finished to the required grip diameter while mounted in the chuck to ensure concentricity.
