Built from submicron carbide in the MT7 grade, the insert carries a TiAlN (titanium aluminum nitride) coating that extends tool life under the heat and friction of thread milling. At 0.122 inches (3.1 mm) thick and styled as a 14I insert, it is engineered for use in thread milling toolholders on CNC machining centers. Installation and changeout are handled by CNC machinists and tooling specialists working to ANSI B1.1-1989 dimensional requirements for unified national thread forms.\u003c\/p\u003e\u003cp\u003eThis insert is intended for internal UN thread milling in precision machining environments. The TiAlN finish makes it well suited for dry or semi-dry cutting in ferrous and hardened materials where heat resistance is a priority. The 12 TPI specification covers a range of common unified thread pitches used in general industrial and mechanical assembly applications. This is not a single-point threading insert; it is sized and styled for indexable thread mill bodies used on multi-axis CNC platforms.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron carbide substrate in MT7 grade for consistent edge integrity\u003c\/li\u003e\n\u003cli\u003eTiAlN coating improves heat resistance and extends tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003e12 TPI for internal UN thread milling per ANSI B1.1-1989\u003c\/li\u003e\n\u003cli\u003eInsert thickness of 0.122 inches (3.1 mm) for precise seating in compatible toolholders\u003c\/li\u003e\n\u003cli\u003e14I insert style for use with matching thread mill bodies\u003c\/li\u003e\n\u003cli\u003eNon-conical geometry for straight-flank UN thread profiles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in thread mill toolholders that accept the 14I insert style.

Power down and lock out the machine spindle before changing inserts. Use the appropriate torque wrench and insert screw specified by the toolholder manufacturer  -  do not overtighten the clamping screw. Verify runout and tool projection after indexing 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: 14I\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 14\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 \/ Finish\u003c\/strong\u003e: TiAlN\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: 12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConical\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.122 inches (3.1 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: ANSI B1.1-1989\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: CE, ISO 9001:2015, ISO 13485:2016, ISO 14001:2015, ISO 45001\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: CARMEX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 14I12UNMT7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CARMEX","offers":[{"title":"Default Title","offer_id":51972381737266,"sku":"14I12UNMT7","price":411.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1df783c99e1567dad561120ea4327021.jpg?v=1789967234","url":"https:\/\/voomisupply.com\/products\/carmex-14i12unmt7-carbide-thread-mill-insert-12-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
