Coated with TiAlN finish, this insert handles both internal and external threading operations in a single tool path. The conical insert geometry conforms to ANSI B1.20.1-1983, the governing standard for NPT thread form and taper. Built from submicron carbide in the MT7 grade, it delivers the edge retention and heat resistance that high-speed thread milling demands. Insert thickness is 0.2165 inches (5.50 mm). Machinists and tool-and-die professionals running CNC thread milling operations on pipe thread applications are the primary users.\u003c\/p\u003e\u003cp\u003eThis insert is suited for thread milling NPT pipe threads in production and job-shop environments where both internal and external thread forms are required on the same part. The 8 TPI pitch matches standard NPT sizing for common pipe fittings and valve bodies. Applications span industrial machining, fluid system component production, and manufacturing environments that hold NPT thread tolerances to ANSI B1.20.1-1983. The insert style code is 30IE, indicating compatibility with 30-series insert-style thread mill bodies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron carbide substrate in MT7 grade for extended tool life in demanding materials\u003c\/li\u003e\n\u003cli\u003eTiAlN coating improves heat resistance and reduces built-up edge at high cutting speeds\u003c\/li\u003e\n\u003cli\u003eCuts both internal and external NPT threads  -  eliminating the need for two separate inserts\u003c\/li\u003e\n\u003cli\u003eConical geometry machined to ANSI B1.20.1-1983 NPT thread standard\u003c\/li\u003e\n\u003cli\u003e8 TPI pitch for standard NPT pipe thread applications\u003c\/li\u003e\n\u003cli\u003eInsert thickness of 0.2165 inches (5.50 mm) for precise seating in compatible tool bodies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 30-series CARMEX thread mill insert bodies accepting the 30IE insert style.

Use the correct torque wrench and insert screw as specified by the tool body manufacturer; do not overtighten clamping screws. Inspect the insert seating pocket for chips or debris before installation to ensure full, flat insert contact. Follow applicable shop safety protocols and manufacturer guidelines for insert indexing and disposal.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 30IE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 30\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: MT7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal and External\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch\u003c\/strong\u003e: 8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConical\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: ANSI B1.20.1-1983\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.2165 inches (5.50 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: CE, ISO 13485:2016, ISO 14001:2015, ISO 45001, ISO 9001:2015\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 30-8NPTMT7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CARMEX","offers":[{"title":"Default Title","offer_id":51975301824818,"sku":"30-8NPTMT7","price":867.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/df7b1f2a591c17158deea78f3654fe20.jpg?v=1789977889","url":"https:\/\/voomisupply.com\/products\/carmex-30-8nptmt7-carbide-thread-mill-insert-8-tpi-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
