Manufactured in the IC908 submicron carbide grade with a PVD-applied TiN\/TiAlN coating, this insert handles a broad range of thread pitches from 48 to 16 TPI (0.50 to 1.50 mm pitch) in a single 60-degree profile geometry. The 3\/8 inch (9.53 mm) inscribed circle and 0.143 inch thickness conform to the 16ER insert style standard. Right-hand cutting orientation makes it the standard choice for conventional external threading passes. Licensed machinists, CNC operators, and production turning shops install and index this insert during scheduled tooling maintenance.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for external threading operations on turning centers and manual lathes across a wide range of workpiece materials. The IC908 grade with H, K, M, N, P, and S material group ratings gives it universal applicability across steels, stainless steels, cast irons, non-ferrous alloys, high-temperature alloys, and hardened materials. It is commonly used in job shop and production environments where a single insert geometry must cover multiple thread pitches without a toolholder change. The B chipbreaker geometry supports controlled chip evacuation during threading passes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eIC908 submicron solid carbide grade with PVD TiN\/TiAlN coating for extended tool life\u003c\/li\u003e\n  \u003cli\u003e60-degree external partial profile geometry covers 48-16 TPI (0.50-1.50 mm pitch range) in one insert\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting orientation, 16ER insert style, fits standard 16ER toolholders\u003c\/li\u003e\n  \u003cli\u003eUniversal material compatibility: ISO material groups H, K, M, N, P, and S\u003c\/li\u003e\n  \u003cli\u003eB chipbreaker for controlled chip flow during external threading\u003c\/li\u003e\n  \u003cli\u003eConforms to ISO 13399 tooling data standards for CAM and tool management integration\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement insert for standard 16ER external threading toolholders.

Use the appropriate torque wrench and insert clamp screw driver specified by the toolholder manufacturer when seating the insert. Inspect the insert pocket and clamping surfaces for wear or debris before seating a new insert. Do not use a damaged or chipped insert, as this can compromise thread form accuracy and create a hazard during cutting.\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\u003eMaterial Grade\u003c\/strong\u003e: Submicron\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\u003eThread Type\u003c\/strong\u003e: External Partial Profile\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 48-16 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch Range\u003c\/strong\u003e: 0.50 to 1.50 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\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: 0.375 inches (9.53 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.143 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.002 inches (0.05 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Code\u003c\/strong\u003e: H; K; M; N; P; S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: ISCARTHREAD\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\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: 5901944\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51748511678770,"sku":"5901944","price":179.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/21b59d153860d1067a4a0c2f51fa6ad1.jpg?v=1788894657","url":"https:\/\/voomisupply.com\/products\/iscar-5901944-threading-insert-60-deg-48-16-tpi-ic908","provider":"Voomi Supply","version":"1.0","type":"link"}
