Manufactured in grade VK2 and left uncoated, this insert suits applications where base carbide substrate performance is preferred without an additional coating layer. The insert style is 5I with a size code of 5, and it is rated for 8 threads per inch (TPI). Thread mill inserts like this one are installed into compatible thread mill toolholders and used on CNC machining centers to generate internal threads in a helical interpolation path. The VK2 grade carbide provides consistent cutting performance across a range of workpiece materials.\u003c\/p\u003e\u003cp\u003eThis insert is intended for internal thread milling of UN unified inch thread forms at 8 TPI. It is suited for use on CNC machining centers and mill-turn equipment in job shop, production machining, and toolroom environments. The uncoated VK2 carbide construction makes it a practical choice when coating-related edge prep changes are not desirable or when regrinding and re-use of the substrate is part of the workflow. Licensed machinists and CNC programmers typically specify this insert for threading cycles in ferrous and non-ferrous workpiece materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eVK2 carbide grade provides a consistent, reliable cutting edge for internal thread milling\u003c\/li\u003e\n\u003cli\u003e8 TPI rating conforms to ANSI B1.1:74 unified inch thread standards\u003c\/li\u003e\n\u003cli\u003eUncoated substrate allows direct carbide-to-workpiece contact without PVD layer interference\u003c\/li\u003e\n\u003cli\u003eInsert style 5I and size code 5 for use in compatible VARGUS thread mill bodies\u003c\/li\u003e\n\u003cli\u003eInternal thread application geometry optimized for helical interpolation cycles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement insert for compatible VARGUS thread mill toolholders accepting the 5I insert style in size code 5 for internal UN thread milling at 8 TPI.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThread mill inserts should be installed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before changing or seating any insert. Use the appropriate VARGUS torx or hex key specified for the toolholder to avoid stripping the clamping screw. Verify insert seating and runout before initiating a thread milling cycle.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 5I\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 5\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\u003eThreads Per Inch\u003c\/strong\u003e: 8 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Application\u003c\/strong\u003e: Internal\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 (process classification; no coating applied)\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: 0.176 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 64739\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VARGUS","offers":[{"title":"Default Title","offer_id":67915009163570,"sku":"64739","price":122.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6cf31e89f8412858eeaade17ffeb9775.jpg?v=1791251859","url":"https:\/\/voomisupply.com\/products\/vargus-64739-carbide-thread-mill-insert-8-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
