Built from micrograin carbide in insert style 3E, it carries a TiCN coating applied via PVD process, which improves surface hardness and wear resistance during high-cycle threading operations. With a 3\/8 inch (9.53 mm) inscribed circle, the insert seats in compatible thread mill bodies for precise, repeatable thread form generation. This insert is used by machinists and CNC tooling technicians in production environments where thread accuracy and tool longevity are critical.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for external UN thread milling on ferrous and non-ferrous workpiece materials in CNC machining centers. The 28 TPI specification targets fine-pitch thread profiles in the UN standard, making it appropriate for applications where tight thread tolerances are required. It is packaged as a single insert with a minimum order quantity of 10 units, making it a standard replenishment item for shops running ongoing thread milling operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin carbide substrate provides high hardness and edge integrity at elevated cutting speeds\u003c\/li\u003e\n  \u003cli\u003eTiCN coating via PVD process improves wear resistance and reduces built-up edge\u003c\/li\u003e\n  \u003cli\u003e28 TPI external UN thread form for fine-pitch thread milling\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch (9.53 mm) inscribed circle for precise insert seating in compatible bodies\u003c\/li\u003e\n  \u003cli\u003eInsert style 3E geometry engineered for thread mill tooling systems\u003c\/li\u003e\n  \u003cli\u003eManufacturer grade VBX for consistent dimensional and cutting performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement thread mill insert for VARGUS thread milling systems accepting 3E style inserts with a 3\/8 inch inscribed circle.

Always power down and lock out the machine spindle before changing inserts. Use the appropriate torx or hex key as specified by the tool body manufacturer when seating the insert, and verify insert clamping torque meets the tool body specification. Inspect the insert pocket for wear or debris before installing a new insert to ensure proper seating and thread accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 3E\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: Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: VBX\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: 28\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (9.53 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.423 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: 64968\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VARGUS","offers":[{"title":"Default Title","offer_id":67907611787570,"sku":"64968","price":598.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a374caf42aa5e1be0468fe559a2f3431_88874de1-2fbb-4b1b-a9b9-0f7a44c8bd2d.jpg?v=1791180729","url":"https:\/\/voomisupply.com\/products\/vargus-64968-carbide-thread-mill-insert-28-tpi-un","provider":"Voomi Supply","version":"1.0","type":"link"}
