It carries a TiAlN finish and is built from submicron carbide in manufacturer grade MT7. The insert produces UN-standard external threads at 14 teeth per inch (TPI), conforming to ANSI B1.1-1989. It measures 0.185 inches in thickness. This insert is used by machinists and CNC tooling specialists in precision threading applications where consistent thread geometry and tool life are critical.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for external thread milling on CNC machining centers handling UN-standard threads at 14 TPI. The non-conical profile and submicron carbide substrate make it appropriate for ferrous and non-ferrous materials where wear resistance and surface finish quality are priorities. Typical install environments include job shops and production facilities running high-duty thread milling cycles. The insert style designation is 21E with an insert size code of 21.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSubmicron carbide substrate in MT7 grade for extended tool life in demanding threading operations\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating provides heat and wear resistance during high-speed thread milling\u003c\/li\u003e\n  \u003cli\u003eProduces external UN-standard threads at 14 TPI per ANSI B1.1-1989\u003c\/li\u003e\n  \u003cli\u003eNon-conical insert geometry for consistent thread form across the full cutting depth\u003c\/li\u003e\n  \u003cli\u003eInsert thickness of 0.185 inches ensures stable seating in compatible tool bodies\u003c\/li\u003e\n  \u003cli\u003eMeets CE, ISO 9001:2015, ISO 13485:2016, ISO 14001:2015, and ISO 45001 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement insert for thread mill tool bodies accepting the 21E insert style with a size code of 21.

Power down and lock out the machine spindle before changing inserts. Use the appropriate torque wrench and insert screw specified by the tool body manufacturer  -  do not overtighten, as carbide inserts are brittle and susceptible to fracture under excessive clamping force. Inspect the insert pocket for debris or damage before seating the new insert.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 21E\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 21\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: External\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 (TPI)\u003c\/strong\u003e: 14\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: 0.185 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\u003eCertifications\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: 21E14UNMT7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CARMEX","offers":[{"title":"Default Title","offer_id":52098194932018,"sku":"21E14UNMT7","price":518.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dc6908409fb5b182fa48a7b3afcdafa2_39fb5782-d20d-48ba-82a6-f88f6a94e98f.jpg?v=1790067408","url":"https:\/\/voomisupply.com\/products\/carmex-21e14unmt7-carbide-thread-mill-insert-14-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
