Abbott Workholding Products TG8HDS1 Soft Lathe Chuck Jaw

Product Description

The ABBOTT WORKHOLDING PRODUCTS TG8HDS1 is a soft lathe chuck jaw with a tongue and groove interface, designed for use in 3-jaw lathe chuck setups. Machined from 1018 steel, this square-profile jaw measures 4 inches overall length, 3 inches overall height, and 1.5 inches overall width. The tongue and groove design provides a secure, repeatable seating interface. Weighing 14.5 pounds, the TG8HDS1 is a solid, heavy-duty component suited for professional machine shop environments where precision workholding is required on engine lathes and similar turning equipment.

This jaw is intended for use with lathe chucks up to 8 inches in maximum chuck diameter. The tongue and groove interface is a standard configuration found on many 3-jaw soft chuck assemblies used in production and job-shop turning applications. Soft jaws of this type are typically bored or machined in place by the operator to match the specific workpiece geometry, making them appropriate for holding irregular, pre-machined, or finish-ground parts where standard hard jaws would cause damage or insufficient grip. This jaw is sold individually and is compatible with 3-jaw chuck configurations.

Installation Notes

Installation is performed by qualified machinists or lathe operators. Always power down and lock out the lathe before mounting or removing chuck jaws. Verify that all jaw fasteners are torqued evenly and that the jaw seats fully in the groove before running the spindle. Soft jaws should be bored to size while mounted in the chuck to ensure concentricity with the spindle centerline.
