Manufactured from submicron carbide with a TiAlN finish, this insert provides wear resistance and thermal stability during thread milling on CNC machining centers. It carries the MT7 manufacturer grade designation and is designed to produce internal threads at 12 teeth per inch. The insert thickness measures 0.2170 inches. Machinists and CNC operators in production shops and job shops install this type of insert when thread milling is preferred over tapping, particularly in hardened materials or blind-hole applications where tap breakage is a concern.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for internal UN thread milling in ferrous and non-ferrous materials where consistent thread form and finish are required. It follows the ANSI B1.1-1989 standard for Unified National thread forms. Typical applications include aerospace, automotive, and general metalworking environments where tight thread tolerances are maintained on CNC machining centers. The non-conical geometry and 30I insert style make it compatible with thread mill bodies designed for that insert configuration.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSubmicron carbide substrate for improved hardness and edge retention\u003c\/li\u003e\n  \u003cli\u003eTiAlN finish for thermal resistance and extended tool life in dry or semi-dry cutting\u003c\/li\u003e\n  \u003cli\u003e12 teeth per inch for UN internal thread milling per ANSI B1.1-1989\u003c\/li\u003e\n  \u003cli\u003eMT7 grade designation engineered for thread milling performance\u003c\/li\u003e\n  \u003cli\u003eNon-conical insert geometry in the 30I insert style\u003c\/li\u003e\n  \u003cli\u003eThickness of 0.2170 inches for precise seating in compatible tool bodies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with thread mill bodies that accept the 30I insert style.

Power down and lock out the machine spindle before changing inserts. Use the correct torque wrench or insert key specified by the tool body manufacturer when seating the insert  -  do not overtighten by hand. Verify insert seating and runout before resuming cutting operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 30I\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\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: 12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConical\u003c\/strong\u003e: No\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\u003eThickness\u003c\/strong\u003e: 0.2170 inches\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: 30I12UNMT7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CARMEX","offers":[{"title":"Default Title","offer_id":51993728385330,"sku":"30I12UNMT7","price":779.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/66c8890ecd8a9ef6cfb229730348a06e.jpg?v=1789991322","url":"https:\/\/voomisupply.com\/products\/carmex-30i12unmt7-carbide-thread-mill-insert-12-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
