It runs a 3-flute, right-hand cutting geometry with a 0.2850-inch cutting diameter and a 5\/16-inch (0.3125-inch) shank diameter. The 3\/4-inch length of cut accommodates standard thread engagement depths at 16 teeth per inch. An AlCrN coating provides heat and wear resistance during high-speed milling operations. This tool is used by machinists and tooling specialists in CNC machining centers where thread milling is preferred over tapping for precision, tool life, or application requirements.\u003c\/p\u003e\n\u003cp\u003eThis thread mill suits CNC machining applications requiring 3\/8-16 UN internal or external threads in materials where solid carbide tooling and AlCrN coating offer an advantage over high-speed steel alternatives. Coolant-through capability supports chip evacuation and thermal management during the cut, making it appropriate for ferrous and non-ferrous workpieces in production or job-shop environments. The right-hand flute direction is standard for conventional thread milling cycles on CNC machining centers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCuts 3\/8-16 UN threads in both internal and external configurations with a single tool\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eAlCrN coating for elevated-temperature performance and extended tool life\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design aids chip evacuation and heat control at the cutting edge\u003c\/li\u003e\n  \u003cli\u003e3-flute, right-hand helical geometry for smooth, balanced cutting action\u003c\/li\u003e\n  \u003cli\u003eCutting diameter tolerance of +0.0000 to -0.0020 inches supports consistent thread quality\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers capable of helical interpolation; compatible with standard 5\/16-inch collet or end mill holders.

Secure the 5\/16-inch shank in a compatible collet or milling chuck to the holder manufacturer's specified torque. Verify coolant-through passages are clear before running the tool at programmed feed and speed. Thread milling requires a helical interpolation cycle in the CNC program; confirm cycle parameters match the 3\/8-16 UN thread specification before cutting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlCrN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\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 and External\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch (TPI)\u003c\/strong\u003e: 16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.2850 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0020 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.7500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length Tolerance\u003c\/strong\u003e: +0.0300 to -0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Nominal Diameter\u003c\/strong\u003e: 0.3750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: 0.0600 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242117\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: SECO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 17000435\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51560104165682,"sku":"17000435","price":392.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ef02580b5c62e6bc70e33ab855f9646c.jpg?v=1786446595","url":"https:\/\/voomisupply.com\/products\/seco-17000435-thread-mill-3-8-16-3-flute-solid-carbide-alcrn","provider":"Voomi Supply","version":"1.0","type":"link"}
