Built from steel with a right-hand orientation, this toolholder accepts LT 11NR series inserts secured by a screw-clamp holding method. The shank measures 0.75 inches in both width and height, with an overall length of 7 inches. A minimum bore diameter of 0.5 inches defines the smallest internal feature it can enter. The toolholder carries a Toolholder Style designation of S06 and belongs to the LT Threading series. Machinists and CNC operators working in production threading applications will find this a direct-fit, OEM-style solution.\u003c\/p\u003e\n\u003cp\u003eThis toolholder is suited for internal threading on ferrous and non-ferrous workpieces in both job-shop and production environments. The right-hand cutting orientation is standard for conventional lathe setups where the tool feeds toward the chuck. With a head length of 1 inch and a back-of-bar to cutting edge distance of 0.28 inches, it provides consistent insert positioning for repeatable thread form accuracy. It does not feature coolant-through capability, making it appropriate for external coolant delivery setups. Typical applications include threading bores in hydraulic components, fittings, and mechanical assemblies requiring precise thread profiles.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInternal, right-hand thread cutting orientation for standard lathe setups\u003c\/li\u003e\n  \u003cli\u003eAccepts LT 11NR series inserts with screw-clamp holding method for positive insert retention\u003c\/li\u003e\n  \u003cli\u003eSteel construction for rigidity and durability in continuous threading operations\u003c\/li\u003e\n  \u003cli\u003e0.5 inch minimum bore diameter allows threading of smaller internal features\u003c\/li\u003e\n  \u003cli\u003eOverall length of 7 inches with a 1 inch head length for reach and stability\u003c\/li\u003e\n  \u003cli\u003eS06 Toolholder Style designation for straightforward catalog cross-referencing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard-fit toolholder for CNC lathes and turning centers that accept S06-style internal threading toolholders with LT 11NR series inserts.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or CNC operators. Power down and lock out the machine spindle before mounting or removing the toolholder from the turret. Confirm proper insert seating and screw torque according to the machine shop standard procedure before initiating a threading pass. Verify bore clearance against the 0.5 inch minimum bore diameter specification before setup to avoid tool or workpiece interference.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: S06\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: LT Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: LT 11NR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Width\/Diameter\u003c\/strong\u003e: 0.75 inches (19.05 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Height\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7 inches (177.80 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 1 inch (25.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 0.28 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter to Cutting Edge\u003c\/strong\u003e: 0.28 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.7275 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291800\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: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1288896\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51734996255026,"sku":"1288896","price":275.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d00552a0d54fd70a795b05cc86b9d49d.jpg?v=1788769027","url":"https:\/\/voomisupply.com\/products\/kennametal-1288896-indexable-threading-toolholder","provider":"Voomi Supply","version":"1.0","type":"link"}
