Manufactured from solid carbide with a TiAlN PVD coating applied under the IC908 grade designation, this insert delivers wear resistance and thermal stability during threading operations. It covers a thread range of 48 to 8 TPI and a pitch range of 0.50 to 3.00 mm, making it suitable for cutting a wide range of standard thread pitches in a single insert style. The left-hand orientation suits setups requiring reverse-hand threading. Machinists and CNC operators in precision machining environments install this insert in compatible laydown-style threading toolholders.\u003c\/p\u003e\u003cp\u003eThis insert is intended for internal threading applications on lathes and turning centers. The IC908 PVD-coated solid carbide grade performs across universal workpiece materials, including steel, stainless, cast iron, non-ferrous alloys, and high-temperature alloys, as designated by ISO material codes H, K, M, N, P, and S. The 16IL insert style fits into corresponding 16IL-series toolholders. It is suited to both production and maintenance threading tasks in job shop and production machining environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with TiAlN PVD coating for extended tool life\u003c\/li\u003e\n\u003cli\u003eIC908 grade rated for universal workpiece material compatibility across ISO codes H, K, M, N, P, and S\u003c\/li\u003e\n\u003cli\u003eLeft-hand internal partial profile 60-degree thread form\u003c\/li\u003e\n\u003cli\u003eCovers 48 to 8 TPI and 0.50 to 3.00 mm pitch range in a single insert\u003c\/li\u003e\n\u003cli\u003e3\/8 inch (0.375 inch) inscribed circle with 0.143 inch thickness for laydown-style seating\u003c\/li\u003e\n\u003cli\u003eCompliant with ISO 13399 cutting tool data standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in 16IL-series laydown threading toolholders compatible with the ISCARTHREAD series.

Power down and lock out the machine spindle before changing inserts. Use the correct torx or hex key to the toolholder manufacturer's specified seating procedure to avoid rocking or improper clamping. Inspect the insert pocket for debris or wear before seating a new insert, as a damaged pocket will affect thread accuracy and insert life.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 16IL\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 Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal 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 to 8 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch Range\u003c\/strong\u003e: 0.50 to 3.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.375 inch decimal)\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\u003c\/strong\u003e: Universal (ISO H, K, M, N, P, S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO 13399\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: 5902121\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51745359495474,"sku":"5902121","price":179.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/93ba6f904973b8bdb61c287ea1c20a2c.jpg?v=1788863616","url":"https:\/\/voomisupply.com\/products\/iscar-5902121-threading-insert-60-degree-48-8-tpi-left-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
