Abbott Workholding TG6MDA2 Soft Lathe Chuck Jaw Tongue Groove

Product Description

The ABBOTT WORKHOLDING PRODUCTS TG6MDA2 is a soft lathe chuck jaw with a tongue-and-groove interface, machined from 6061-T6 aluminum. Soft jaws are machinable to custom bore profiles, allowing machinists to match part geometry precisely and reduce workholding-induced distortion on thin-walled or finish-machined workpieces. This jaw measures 1.25 inches in overall width, 3 inches in overall height, and 3 inches in overall length, with mount hole centers spaced 1.5 inches apart. The tongue width is 0.5 inches and the groove width is 0.313 inches. It is compatible with chucks up to 6 inches in diameter and is sold as a set of 3 jaws.

This jaw is intended for use on manual and CNC lathes in machine shops, tool rooms, and production turning cells. The aluminum construction keeps rotational mass low, which benefits high-speed turning applications. The tongue-and-groove interface provides repeatable jaw registration when jaws are swapped between jobs. Typical users include CNC machinists, tool and die makers, and lathe operators who need a reliable soft jaw solution for precision turning work on aluminum, brass, or soft-metal workpieces.

Key Features

Compatibility

Designed for use with lathe chucks up to 6 inches in maximum compatible chuck diameter using a tongue-and-groove jaw interface. Verify chuck jaw interface dimensions, including tongue width of 0.5 inches and groove width of 0.313 inches, against your specific chuck model before installation.

Installation Notes

Installation should be performed by a qualified machinist with the lathe powered down and locked out per applicable machine safety procedures. Confirm all jaw fasteners are torqued to the chuck manufacturer's specification before running the spindle. After boring soft jaws to the required profile, take a light facing pass to true the jaw faces to the spindle centerline. Never exceed the chuck's rated speed with rebored jaws, as material removal changes the jaw mass balance.
