Built to the IC908 grade with a PVD-applied TiAlN coating, this insert delivers consistent thread form on a broad range of workpiece materials. The 3\/8 inch (0.375 inches) inscribed circle and 0.143 inch thickness conform to standard laydown seating geometry, allowing drop-in use in compatible toolholders. Licensed machinists and CNC lathe operators in production and job-shop environments rely on IC908-grade inserts for their toughness and wear resistance across interrupted and continuous threading cuts.\u003c\/p\u003e\u003cp\u003eThis insert is suited for external UN threading operations on lathes and turning centers where left-hand thread forms are required. The universal primary workpiece material rating covers a wide cross-section of metals, including steel, stainless steel, cast iron, aluminum, and superalloys, as indicated by material codes H, K, M, N, P, and S. It fits within the ISCARTHREAD series toolholder system and is intended for applications demanding precise 16 TPI UN thread profiles on left-hand threaded components.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eIC908 solid carbide grade with PVD TiAlN coating for extended tool life\u003c\/li\u003e\n\u003cli\u003e16 TPI left-hand external UN thread form in laydown insert style\u003c\/li\u003e\n\u003cli\u003e3\/8 inch inscribed circle for standard laydown toolholder compatibility\u003c\/li\u003e\n\u003cli\u003eUniversal material compatibility covering steel, stainless, cast iron, aluminum, and superalloys\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.007 inches (0.18 mm) for accurate thread root form\u003c\/li\u003e\n\u003cli\u003eCompliant with ISO 13399 cutting tool data representation standard\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with ISCARTHREAD series toolholders that accept 16EL style laydown threading inserts with a 3\/8 inch inscribed circle seating geometry.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThreading inserts must be seated fully and clamped securely in the toolholder before initiating any cut. Power down and lock out the machine spindle before changing inserts. Verify that the toolholder and insert style codes match before installation, as mixing incompatible geometries can result in insert failure or thread-form error. This insert is a precision cutting tool; handle the cutting edges with care to avoid chipping prior to use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 16EL\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\/Finish\u003c\/strong\u003e: TiAlN, PVD Process\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\u003eInsert Hand\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\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: 0.007 inches (0.18 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\u003eSeries\u003c\/strong\u003e: ISCARTHREAD\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: 5902352\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51755083399474,"sku":"5902352","price":178.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/90a02cbc31b90a0d36ed912e7b5ac3a8.jpg?v=1788950956","url":"https:\/\/voomisupply.com\/products\/iscar-5902352-threading-insert-16-tpi-left-hand-un","provider":"Voomi Supply","version":"1.0","type":"link"}
