Built to insert style C12 with a manufacturer grade of MT7 and a submicron carbide substrate, it carries a TiAlN coating that improves heat resistance and extends tool life in interrupted cuts and continuous threading passes. This insert is installed by machinists and toolroom technicians working in precision threading applications where consistent thread form and surface finish are critical across production runs.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for internal threading operations on ferrous and non-ferrous workpiece materials in job shop and production machining environments. The UN thread standard coverage makes it a practical choice for standard inch-series fastener and fitting thread forms commonly encountered in general manufacturing, fluid power, and industrial assembly applications. The TiAlN finish provides added durability when cutting at elevated surface speeds.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInsert style C12 geometry optimized for internal UN threading\u003c\/li\u003e\n  \u003cli\u003eMT7 manufacturer grade for consistent thread form accuracy\u003c\/li\u003e\n  \u003cli\u003eSubmicron carbide material grade for improved toughness and edge integrity\u003c\/li\u003e\n  \u003cli\u003eTiAlN finish enhances heat resistance and extends cutting life\u003c\/li\u003e\n  \u003cli\u003eUN thread standard coverage for standard inch-series internal threads\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct equivalent threading insert for toolholders and boring bars compatible with C12 insert style geometry used in internal UN thread turning operations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThreading inserts of this type are seated and torqued into compatible toolholders by qualified machinists following the toolholder manufacturer's clamping procedure. Power down and lock out the spindle before changing inserts. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert. Handle carbide inserts carefully to avoid chipping the cutting edge prior to use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: C12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: MT7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Submicron\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\u003eFinish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291804\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: C12I28UNMT7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CARMEX","offers":[{"title":"Default Title","offer_id":52056154997042,"sku":"C12I28UNMT7","price":310.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/72c8ae6a346f7ca51002635e6b5c4ebe.jpg?v=1790038071","url":"https:\/\/voomisupply.com\/products\/carmex-c12i28unmt7-threading-insert-un-internal-mt7","provider":"Voomi Supply","version":"1.0","type":"link"}
