Manufactured in the 16IR insert style with an IC908 grade substrate, it features a PVD-applied TiAlN coating that supports demanding cutting conditions across a wide range of workpiece materials. The insert has a 3\/8-inch (0.375 inches) inscribed circle and a thickness of 0.143 inches. It carries a right-hand cutting orientation and an M chipbreaker geometry. Licensed machinists and CNC lathe operators working in pipe-thread applications will find this insert suited to precision internal threading work where consistent thread form and tool life are priorities.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for internal NPT (National Pipe Taper) threading operations on CNC lathes and manual threading setups. The IC908 grade with PVD coating is rated for use across universal workpiece materials, including material groups H, K, M, N, P, and S, covering steels, stainless steels, cast irons, non-ferrous metals, high-temperature alloys, and hardened materials. It is part of the ISCARTHREAD series and conforms to ISO 13399 tooling data standards. Typical applications include threading pipe fittings, hydraulic components, and fluid-system parts requiring NPT-standard internal threads.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with IC908 grade substrate for wear resistance and edge stability\u003c\/li\u003e\n  \u003cli\u003ePVD-applied TiAlN coating extends tool life across diverse workpiece materials\u003c\/li\u003e\n  \u003cli\u003e11.5 TPI internal NPT thread form for standard pipe-taper threading applications\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting orientation with M chipbreaker geometry\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch inscribed circle (0.375 inches) and 0.143 inches thickness in 16IR insert style\u003c\/li\u003e\n  \u003cli\u003eConforms to ISO 13399 tooling data standard for seamless integration with CAM and tool management systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement-style insert for 16IR internal threading toolholders accepting a 3\/8-inch inscribed circle laydown insert.

Power down and lock out the machine spindle before seating or removing inserts. Use the appropriate torx or clamping screw driver to the toolholder manufacturer's recommended procedure  -  do not overtighten the clamping screw, as this can fracture the carbide insert. Confirm insert orientation and thread hand before commencing the threading pass.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 16IR\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 Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 11.5 TPI\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: M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.375 inches)\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: 0.09 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade Compatibility\u003c\/strong\u003e: C1, C2, C6, C7\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: 0.01 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\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: 5901584\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51742445011250,"sku":"5901584","price":150.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5a9c1de856e4c7789ea8156b4879fb97.jpg?v=1788837511","url":"https:\/\/voomisupply.com\/products\/iscar-5901584-threading-insert-11-5-tpi-npt-ic908","provider":"Voomi Supply","version":"1.0","type":"link"}
