Abbott Workholding Products AL3103 Soft Lathe Chuck Jaw

Product Description

The ABBOTT WORKHOLDING PRODUCTS AL3103 is a soft lathe chuck jaw designed for precision turning applications on CNC and manual lathes. Machined from 6061-T6 aluminum, this round jaw features a tongue and groove interface and accommodates a maximum internal or external chucking diameter of 9.75 inches. At 3 inches overall height and 9.92 inches overall diameter, it provides a stable, machinable soft jaw profile that technicians can bore to match specific workpiece geometries. It is sold as a set of 3 jaws and is used by machinists and toolroom professionals who require a reliable, rebore-capable jaw for repeat setups.

The AL3103 suits lathe work in machine shops, toolrooms, and production environments where workholding accuracy is critical. Its aluminum construction reduces rotating mass compared to steel jaws, making it appropriate for lighter-duty turning and finishing operations. The tongue and groove interface ensures positive jaw registration on compatible 10-inch chuck bodies. Internal chucking range spans 1.0 inch minimum to 9.75 inches maximum, and external chucking range spans 0.75 inches minimum to 9.75 inches maximum, covering a broad variety of cylindrical workpieces.

Installation Notes

Soft lathe chuck jaws are installed and bored by a qualified machinist or toolroom technician. Always power down and lock out the lathe before removing or installing chuck jaws. Confirm jaw seating in the tongue and groove slots before applying any clamping force. Bore jaws to final diameter on the machine on which they will be used to ensure concentricity with the spindle centerline.
