Built to insert style 3I with a size code of 3, this uncoated carbide insert runs at 16 threads per inch (TPI) and is manufactured to the ANSI B1.1:74 standard. It is suited for precision thread milling on non-ferrous and similar workpiece materials, making it a practical choice for machine shops and production environments where repeatable thread quality is required. The manufacturer grade is VK2, processed via PVD coating method.\u003c\/p\u003e\n\u003cp\u003eThis insert is used in internal thread milling applications on CNC machining centers and thread milling equipment where UN unified inch thread profiles are required. Typical install scenarios include production threading of through-holes and blind holes in non-ferrous workpiece materials. It is sold individually and is appropriate for shops maintaining single-unit replacement stock for thread mill tooling programs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInternal thread milling insert for UN unified thread forms at 16 TPI\u003c\/li\u003e\n  \u003cli\u003eInsert style 3I, size code 3 for compatibility with matching thread mill bodies\u003c\/li\u003e\n  \u003cli\u003eCarbide substrate with VK2 manufacturer grade for wear resistance\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for primary workpiece material code N (non-ferrous)\u003c\/li\u003e\n  \u003cli\u003eManufactured to ANSI B1.1:74 thread standard\u003c\/li\u003e\n  \u003cli\u003ePVD coating process used in grade production\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 tooling bodies accepting style 3I carbide inserts in size code 3 configurations for internal UN thread milling.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or tooling technicians. The machine spindle must be brought to a full stop and the tool holder secured before seating or replacing the insert. Use the appropriate torx or hex key specified by the tool body manufacturer when tightening the insert screw  -  do not over-torque. Verify thread pitch and insert orientation against the tool body documentation before resuming machining operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 3I\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: VK2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Form\u003c\/strong\u003e: UN (Unified National)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Application\u003c\/strong\u003e: Internal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 16 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Code\u003c\/strong\u003e: N\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: ANSI B1.1:74\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: VARGUS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 64489\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VARGUS","offers":[{"title":"Default Title","offer_id":67912043888946,"sku":"64489","price":72.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b1bfa4a8766650af324a479b6b035607_e5825a35-d77b-4ca2-9217-8c99ec907318.jpg?v=1791225895","url":"https:\/\/voomisupply.com\/products\/vargus-64489-carbide-thread-mill-insert-un-16-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
