Abbott Workholding Products MTT10A Soft Lathe Chuck Jaw

Product Description

The ABBOTT WORKHOLDING PRODUCTS MTT10A is a soft lathe chuck jaw with a serrated jaw interface, designed for use in metal-turning and machining operations on engine lathes and CNC turning centers. Machined from 6061-T6 aluminum, this square-profile jaw offers a lightweight, machinable blank that technicians and machinists can bore or contour to fit specific workholding requirements. Key dimensions include an overall length of 4.5 inches, an overall height of 2 inches, and an overall width of 1.5 inches. The distance between mount hole centers is 1.2598 inches, and the fastener size is 0.4724 inches. The serrated interface provides positive engagement with the chuck master jaw for repeatable positioning.

This jaw is suited for use on lathes equipped with 3-jaw scroll chucks up to 10 inches in maximum compatible chuck diameter. It is a common choice in job shops, production turning cells, and maintenance machine shops where operators need a soft jaw that can be custom-bored to grip irregular, delicate, or previously finished workpieces without marking. Sold individually, it is compatible with serrated master jaw systems using a 0.63-inch slot width and a 0.4724-inch fastener size. Installation requires a matching set of three jaws for a complete chuck setup.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Power down and lock out the lathe spindle drive before removing or installing chuck jaws.
