Manufactured to the LT11NRA60 style specification with a KC5025 grade, it carries a PVD-applied TiAlN coating for thermal resistance and edge durability under demanding cutting conditions. The insert cuts a partial profile 60-degree thread form on the right-hand internal pass, covering a thread pitch range of 48 to 16 TPI (0.50 to 1.50 mm pitch). With an inscribed circle of 1\/4 inch (6.35 mm) and a thickness of 0.1260 inch (3.04 mm), this insert seats precisely in compatible LT11 style toolholders used in production threading applications.\u003c\/p\u003e\u003cp\u003eThis insert is suited for internal threading in ferrous and non-ferrous workpieces where a unified or metric partial-profile 60-degree thread form is required. It is typically installed in small-bore threading toolholders on CNC turning equipment in job shops, production machining facilities, and aerospace or industrial component manufacturing environments. The TiAlN PVD coating supports higher cutting speeds and extends tool life in steel and stainless steel applications. Machinists and CNC setup technicians are the primary installers for this type of insert.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate with PVD TiAlN coating for extended wear resistance at elevated temperatures\u003c\/li\u003e\n\u003cli\u003ePartial profile 60-degree thread form covers a wide TPI range of 48 to 16 (0.50 to 1.50 mm pitch) with a single insert\u003c\/li\u003e\n\u003cli\u003eRight-hand internal thread geometry for standard bore threading passes\u003c\/li\u003e\n\u003cli\u003eLT11NR insert style with 1\/4 inch inscribed circle fits standard LT11 laydown threading toolholders\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0020 inch (0.05 mm) provides controlled root form at fine to medium pitches\u003c\/li\u003e\n\u003cli\u003eKC5025 grade engineered for consistency in production threading environments\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement threading insert for use in LT11 style laydown threading toolholders accepting a 1\/4 inch inscribed circle insert with a 0.1280 inch hole diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThreading inserts of this type are installed and replaced by machinists or CNC tooling technicians following standard lathe lockout and toolholder torque procedures. Power down and de-energize the machine spindle before changing inserts. Use the correct torque wrench and seating screw specified by the toolholder manufacturer to avoid insert rocking or seating damage. Handle carbide inserts with care to prevent chipping of cutting edges prior to use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 11NR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC5025\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Partial Profile 60 Degree\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 48-16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: 0.50-1.50 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 1\/4 inch (6.35 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1260 inch (3.04 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0020 inch (0.05 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1280 inch (3.25 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0029 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291804\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 1743927\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51730074992946,"sku":"1743927","price":589.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3b4bf13520cfe6583e2726513cb04f5a.jpg?v=1788711310","url":"https:\/\/voomisupply.com\/products\/kennametal-1743927-threading-insert-kc5025-tialn-48-16-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
