Manufactured from submicron solid carbide with a PVD-applied TiAlN coating, this insert delivers wear resistance and thermal stability across a wide range of workpiece materials. It carries an 11IR designation, indicating a right-hand internal threading geometry with a 60-degree included angle. The insert measures 0.25 inches inscribed circle diameter and 0.127 inches thick. It is sized and configured for use in CNC lathes and turning centers, and is typically installed by machinists and toolroom technicians performing precision threading operations.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for internal UN threading applications in both production and job-shop environments. The universal material grade makes it appropriate for use across a broad range of materials including steel, stainless steel, cast iron, non-ferrous alloys, and high-temperature alloys, as indicated by primary workpiece material codes H, K, M, N, P, and S. The BMA manufacturer grade designation reflects Carmex's submicron carbide substrate, optimized for consistent thread form and tool life in right-hand internal threading at 20 TPI.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide submicron substrate for high hardness and edge integrity\u003c\/li\u003e\n  \u003cli\u003eTiAlN PVD coating for elevated temperature resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003e60-degree included angle for standard UN internal thread form at 20 TPI\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut geometry in 11IR laydown-style configuration\u003c\/li\u003e\n  \u003cli\u003eUniversal workpiece material compatibility: steel, stainless, cast iron, non-ferrous, and superalloys\u003c\/li\u003e\n  \u003cli\u003eCE certified and manufactured to ISO 13485:2016, ISO 14001:2015, and ISO 45001 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use threading insert for toolholders accepting the 11IR laydown insert style in internal UN threading applications at 20 TPI.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or toolroom technicians using a calibrated torque wrench and insert clamp screw appropriate for the toolholder manufacturer's specifications. Ensure the machine spindle is fully stopped and the turret is indexed to a safe position before changing inserts. Confirm correct seating of the insert in the pocket before resuming cutting operations. Handle solid carbide inserts carefully to avoid chipping the cutting edge during installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 11IR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.127 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid 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: BMA\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\u003ePrimary Workpiece Material Codes\u003c\/strong\u003e: H; K; M; N; P; S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.064 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: CE; ISO 13485:2016; ISO 14001:2015; ISO 45001\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: CARMEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 20300486\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CARMEX","offers":[{"title":"Default Title","offer_id":52100640637234,"sku":"20300486","price":267.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/55fea4381293f6f0a5d8224b257398ab.jpg?v=1790069159","url":"https:\/\/voomisupply.com\/products\/carmex-20300486-threading-insert-20-tpi-un-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
