Manufactured from submicron carbide in grade MT7 with a TiAlN finish, this insert delivers consistent thread form geometry in demanding milling applications. The TiAlN coating provides elevated heat resistance, making the insert suitable for higher cutting speeds across a range of workpiece materials. At 0.122 inches thick, the insert seats precisely in compatible MT7-grade thread mill bodies. Installation is performed by machinists and tooling technicians in CNC machining environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for internal UN thread milling conforming to ANSI B1.1-1989. It is suited for shops performing thread milling in place of tapping, particularly where thread quality, blind-hole accuracy, or material hardness make conventional tapping impractical. Typical applications include production machining of threaded bores in ferrous and non-ferrous components across general manufacturing, aerospace, and industrial fabrication environments. The insert style code is 14I with size code 14, confirming fitment to compatible 14-series thread mill holders.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSubmicron carbide substrate in MT7 grade for consistent wear resistance\u003c\/li\u003e\n  \u003cli\u003eTiAlN finish for elevated heat resistance at higher cutting speeds\u003c\/li\u003e\n  \u003cli\u003eInternal UN thread profile at 18 TPI conforming to ANSI B1.1-1989\u003c\/li\u003e\n  \u003cli\u003e0.122 inches thickness for precise seating in compatible tool bodies\u003c\/li\u003e\n  \u003cli\u003eNon-conical insert geometry for standard thread mill configurations\u003c\/li\u003e\n  \u003cli\u003eManufactured to ISO 9001:2015, ISO 14001:2015, ISO 13485:2016, ISO 45001, and CE standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with compatible 14-series MT7-grade thread mill holders accepting 14I insert style inserts for internal UN threading applications.

Use the appropriate torx or hex key specified by the tool body manufacturer to secure the insert clamp screw to the correct seating torque per the holder documentation. Inspect the insert pocket and clamping surfaces for chips or debris before seating a new insert. Do not exceed the cutting parameters specified in the thread mill body manufacturer's programming guide for the MT7 grade and workpiece material combination.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\u003eFinish\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: 18 TPI\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\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\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: 14I18UNMT7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CARMEX","offers":[{"title":"Default Title","offer_id":52015685927218,"sku":"14I18UNMT7","price":412.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3f24a201e8c6e94460af2c74d74618f5.jpg?v=1790008049","url":"https:\/\/voomisupply.com\/products\/carmex-14i18unmt7-carbide-thread-mill-insert-18-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
