Manufactured from submicron solid carbide and coated with a PVD-applied TiN\/TiAlN finish under the IC908 grade designation, this insert delivers consistent tool life on a wide range of workpiece materials. The right-hand orientation and 16ER insert style make it a standard choice for external threading operations on CNC lathes and turning centers. The inscribed circle measures 3\/8 inch (0.3750 inches) with a thickness of 0.1430 inches and a corner radius of 0.0020 inches.\u003c\/p\u003e\u003cp\u003eThis insert is suited for external threading applications across general machining environments, including production turning of fasteners, fittings, and threaded shafts. The IC908 grade with PVD coating is rated for universal workpiece materials, covering steel, stainless, cast iron, non-ferrous alloys, and high-temperature alloys as indicated by material codes H, K, M, N, P, and S. It fits standard 16ER insert pockets on compatible threading toolholders and is appropriate for both light production and job-shop threading work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e40 TPI UN external thread form, right-hand cut\u003c\/li\u003e\n\u003cli\u003eIC908 submicron solid carbide grade with PVD TiN\/TiAlN coating\u003c\/li\u003e\n\u003cli\u003e16ER insert style with 3\/8 inch (0.3750 inches) inscribed circle\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0020 inches for precise thread root geometry\u003c\/li\u003e\n\u003cli\u003eChipbreaker style B for controlled chip flow during threading passes\u003c\/li\u003e\n\u003cli\u003eConforms to ISO 13399 tooling data standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned to seat in toolholders accepting the 16ER laydown threading insert style.

Ensure the machine spindle is fully stopped and the toolholder is secured before insert exchange. Confirm insert orientation matches the required thread hand before starting a threading cycle. Inspect the insert pocket and clamping screw for wear or debris prior to installation to ensure repeatable seating.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 16ER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 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: External\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid 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: IC908\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN\/TiAlN, PVD Applied\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 inches \/ 9.53 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1430 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0020 inches (0.05 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Codes\u003c\/strong\u003e: H, K, M, N, P, S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ISO 13399\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.035 pounds\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: 5\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ISCAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5902008\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51743472976178,"sku":"5902008","price":178.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fc65d3c21ec5d1e36aba0717f7474a45.jpg?v=1788847408","url":"https:\/\/voomisupply.com\/products\/iscar-5902008-threading-insert-40-tpi-un-ic908-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
