Sold as a 3-jaw set, these jaws are designed to be bored in-place on the lathe to achieve near-zero runout for precise, repeatable workholding. The serrated interface locks each jaw securely to the chuck body, resisting shifting under cutting loads. Overall jaw dimensions are 1.25 inches wide, 2 inches tall, and 3 inches long, making this set suited for chucks up to 6 inches in diameter. Machinists and tool room operators install these jaws when gripping finished surfaces, soft materials, or irregularly shaped workpieces that standard hard jaws would damage.\u003c\/p\u003e\n\u003cp\u003eThis jaw set is intended for use on manual and CNC lathes equipped with compatible 3-jaw scroll chucks up to 6 inches in diameter. The serrated interface is a widely adopted standard, making these jaws a practical replacement or spare set for production turning, repair shops, and tool rooms. They are particularly well suited for second-operation work where part finish and dimensional accuracy are critical. Mount hole center spacing of 0.7874 inches and a fastener size of 0.3937 inches align with common chuck mounting configurations in this size class.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSerrated square jaw interface for secure, positive engagement with compatible chuck bodies\u003c\/li\u003e\n  \u003cli\u003e6061-T6 aluminum construction allows easy in-place boring to exact workpiece geometry\u003c\/li\u003e\n  \u003cli\u003eCompatible with 3-jaw chucks up to 6 inches in diameter\u003c\/li\u003e\n  \u003cli\u003eMount hole center distance of 0.7874 inches with 0.3937-inch fastener size\u003c\/li\u003e\n  \u003cli\u003eSlot width of 0.472 inches and groove width of 0.4724 inches for consistent fit\u003c\/li\u003e\n  \u003cli\u003eSold as a complete 3-jaw set, ready to bore and install\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement soft jaw set for 3-jaw lathe chucks with a maximum compatible chuck diameter of 6 inches and a serrated jaw interface with 0.7874-inch mount hole center spacing.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSoft jaw installation and boring should be performed by a qualified machinist familiar with lathe workholding procedures. Before removing existing jaws or mounting new ones, power down the lathe and follow lockout-tagout procedures per facility safety standards. Torque fasteners to the chuck manufacturer's specification using the correct hex key or T-handle wrench. Bore jaws in the clamped position under light pre-load to ensure concentricity before taking the final bore pass.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eJaw Shape\u003c\/strong\u003e: Square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eJaw Interface Type\u003c\/strong\u003e: Serrated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 6061-T6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Jaws\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Compatible Chuck Diameter\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDistance Between Mount Hole Centers\u003c\/strong\u003e: 0.7874 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Size\u003c\/strong\u003e: 0.3937 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSlot Width\u003c\/strong\u003e: 0.472 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Width\u003c\/strong\u003e: 0.4724 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.8 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ABBOTT WORKHOLDING PRODUCTS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: KTT6A1SQ\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ABBOTT WORKHOLDING","offers":[{"title":"Default Title","offer_id":67910873776434,"sku":"KTT6A1SQ","price":76.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/83b8709e52d0ce361aacc0ddd224bb44.jpg?v=1791201011","url":"https:\/\/voomisupply.com\/products\/abbott-workholding-ktt6a1sq-soft-lathe-chuck-jaw-serrated","provider":"Voomi Supply","version":"1.0","type":"link"}
