Manufactured from solid carbide in the IC908 grade with a PVD-applied TiN\/TiAlN coating, this insert delivers wear resistance and thermal stability across a wide range of workpiece materials. It cuts a right-hand external Stub Acme thread profile at 6 threads per inch (TPI), with a 9.53 mm (3\/8 inch) inscribed circle and a thickness of 0.143 inches. The 16ER insert style is indexed into compatible ISCARTHREAD toolholders and is suited for production turning where consistent thread form and tool life are priorities.\u003c\/p\u003e\n\u003cp\u003eThis insert is used in external threading operations on ferrous and non-ferrous workpieces, as well as heat-resistant alloys. The Stub Acme thread form is common in power transmission components, linear actuators, lead screws, and mechanical assemblies that require a shallower thread depth than a full Acme profile. The IC908 carbide grade with PVD coating is rated for universal workpiece material compatibility, making it appropriate for steel, stainless, cast iron, aluminum, non-ferrous metals, and high-temperature alloys in both roughing and finishing threading passes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e16ER insert style for right-hand external threading in ISCARTHREAD-compatible toolholders\u003c\/li\u003e\n  \u003cli\u003e6 TPI Stub Acme thread profile for power transmission and linear motion applications\u003c\/li\u003e\n  \u003cli\u003eIC908 solid carbide grade with PVD TiN\/TiAlN coating for broad material compatibility\u003c\/li\u003e\n  \u003cli\u003e9.53 mm (3\/8 inch) inscribed circle for precise seating and repeatability\u003c\/li\u003e\n  \u003cli\u003e0.143 inch insert thickness for stable cutting geometry in laydown orientation\u003c\/li\u003e\n  \u003cli\u003eConforms to ISO 13399 tooling data standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with ISCARTHREAD series external threading toolholders that accept the 16ER insert style.

Ensure the machine spindle is fully stopped and the turret is in a safe index position before seating or replacing inserts. Use the correct torx or clamping key specified for the toolholder to secure the insert without over-torquing the clamping screw. Confirm thread pitch and hand orientation match the programmed toolpath before initiating a threading cycle.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC908\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN\/TiAlN (PVD)\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: Stub Acme\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 6 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 9.53 mm (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.143 inches\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: 0.3 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: ISCAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5902306\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51737471680818,"sku":"5902306","price":50.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2db5965648f20d1a3d797691202274f4_ae41e688-b8cc-44e0-893b-61e69a1571f3.jpg?v=1788788953","url":"https:\/\/voomisupply.com\/products\/iscar-5902306-threading-insert-6-tpi-stub-acme-ic908","provider":"Voomi Supply","version":"1.0","type":"link"}
