Built to the MT LNHU insert style with a size code of 2104, this insert carries the IC908 manufacturer grade and features a TiAlN coating applied via PVD process. It is engineered to cut UN-standard threads at 14 teeth per inch (TPI). The submicron carbide substrate and PVD TiAlN finish provide wear resistance and thermal stability during high-demand milling. This insert belongs to ISCAR's MillThread series and is sold individually with a minimum order quantity of two pieces.\u003c\/p\u003e\u003cp\u003eThis insert is intended for internal thread milling on CNC machining centers and milling machines across a range of workpiece materials. It is rated for use on material groups H, K, M, P, and S, covering hardened steels, cast irons, stainless steels, carbon steels, and heat-resistant superalloys. Typical applications include producing internal UN threads in bored holes where a thread mill toolpath is programmed on the machine. It is primarily installed by CNC machinists and tooling specialists in precision manufacturing, aerospace, automotive, and general metalworking environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eIC908 grade submicron carbide substrate for toughness and wear resistance\u003c\/li\u003e\n\u003cli\u003eTiAlN coating via PVD process for thermal and oxidation resistance\u003c\/li\u003e\n\u003cli\u003eCuts internal UN threads at 14 TPI\u003c\/li\u003e\n\u003cli\u003eCompatible with H, K, M, P, and S workpiece material groups\u003c\/li\u003e\n\u003cli\u003eMT LNHU insert style, size code 2104, part of the MillThread series\u003c\/li\u003e\n\u003cli\u003eConforms to ISO 13399 tooling data standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use insert for ISCAR MillThread series thread mill bodies accepting MT LNHU 2104-style inserts for internal UN thread milling applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis insert is installed and changed by qualified CNC machinists or tooling technicians. Ensure the machine spindle is fully stopped and the machine is placed in an appropriate lockout state before indexing or replacing inserts. Use the correct torx or clamping key specified for the tool body to achieve proper seating torque without over-tightening. Verify insert orientation and thread direction programming before resuming cutting operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: MT LNHU\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 2104\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Submicron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC908\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: UN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch\u003c\/strong\u003e: 14\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: MillThread\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.189 inches (4.8 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Codes\u003c\/strong\u003e: H, K, M, P, S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ISO 13399\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ISCAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5669485\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51730997379378,"sku":"5669485","price":198.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f739d338d366caf72ad8571235e23cc5.jpg?v=1788725621","url":"https:\/\/voomisupply.com\/products\/iscar-5669485-carbide-thread-mill-insert-ic908-un-14-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
