Abbott Workholding CIKTT8P Soft Lathe Chuck Jaw 8 in

Product Description

The ABBOTT WORKHOLDING PRODUCTS CIKTT8P is a serrated soft lathe chuck jaw designed for use in 3-jaw lathe chuck setups on manual and CNC turning equipment. Cast from iron, this round-profile jaw measures 8 inches in overall width and 2 inches in overall height. The serrated interface provides a repeatable mechanical engagement with the chuck body, allowing the jaw to be repositioned accurately during setup. Machinists and tool-room technicians select soft jaws when a workpiece requires custom boring to achieve precise, low-runout clamping on finished or delicate surfaces.

This jaw is suited for use in machine shops, production turning cells, and job-shop environments where a standard 8-inch chuck is in service. The round jaw shape is typical for applications requiring the jaw face to be bored to a specific diameter to match a part contour. With a distance between mount hole centers of 0.9843 inches and a fastener size of 0.4724 inches, the jaw is matched to chuck bodies with corresponding T-slot or serrated mounting geometry. The slot width of 0.5510 inches and groove width of 0.5512 inches confirm chuck interface fitment before ordering.

Compatibility

Designed for use with 3-jaw lathe chucks having a maximum compatible chuck diameter of 8 inches, a serrated jaw interface, a mount hole center distance of 0.9843 inches, a fastener size of 0.4724 inches, and a slot and groove width of approximately 0.5510 to 0.5512 inches. Verify all interface dimensions against the chuck manufacturer specifications before installation.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician with the lathe fully powered down and the spindle locked. Inspect the chuck body serrations and T-slots for wear or debris before seating the jaw. Fasten to the specified torque range per the chuck manufacturer guidelines using the correct fastener size. After installation, bore the soft jaw to the required workpiece diameter before placing the part in service.
