Abbott Workholding Products KTT15S1 Soft Lathe Chuck Jaw

Product Description

The ABBOTT WORKHOLDING PRODUCTS KTT15S1 is a soft lathe chuck jaw with a serrated interface, designed for precision workholding in metal turning applications. Soft jaws are machinable, allowing the technician to bore them to a custom grip profile that conforms to a specific workpiece. The serrated interface locks the jaw securely to the chuck body, preventing slippage under cutting loads. Made from 1018 steel, this jaw measures 6.5 inches in overall length, 4 inches in overall height, and 2.5 inches in overall width. It is installed by machinists and CNC lathe operators as part of a three-jaw chuck assembly on manual or CNC turning centers.

This jaw is suited for use on lathes requiring a three-jaw soft jaw set with a serrated mounting interface. It is compatible with chuck diameters ranging from 15 inches to 18 inches. The serrated groove width of 0.866 inches and mount hole center spacing of 1.6929 inches are critical fitment dimensions that should be verified against the chuck body before ordering. Typical applications include production turning, fixture work, and any operation where standard hard jaws cannot provide the grip geometry needed for a specific part profile.

Key Features

• Serrated jaw interface for positive, slip-resistant seating on compatible chuck bodies
• Machinable 1018 steel construction allows boring to custom grip profiles
• Square jaw shape provides stable, predictable contact geometry
• Compatible with chuck diameters from 15 inches to 18 inches
• Groove width of 0.866 inches and mount hole spacing of 1.6929 inches for precise fitment
• Sold individually to allow replacement of a single jaw without purchasing a full set

Compatibility

Designed for three-jaw lathe chucks with a serrated jaw interface, a groove width of 0.866 inches, and a compatible chuck diameter between 15 inches and 18 inches. Verify mount hole center distance of 1.6929 inches and fastener size of 0.7874 inches against the chuck body specifications before installation.

Installation Notes

Installation is performed by a qualified machinist or CNC lathe operator with the spindle locked and all power isolated from the machine. Confirm that the serrated interface seats fully and evenly against the chuck body before torquing fasteners. After boring the soft jaw to the required profile, verify runout with a dial indicator before beginning production. Follow the chuck manufacturer's torque recommendations for the mounting fasteners.
