Built from solid carbide with an IC908 grade designation and a PVD-applied TiAlN coating, this insert delivers consistent thread form accuracy and extended tool life in demanding production environments. It carries a 16ER insert style profile with a 3\/8 inch (0.375 inches) inscribed circle and a thickness of 0.143 inches. The 14 TPI pitch matches the NPT standard for tapered pipe thread applications. Installation and use require a compatible 16ER-profile threading toolholder. This insert is intended for use by machinists and tooling professionals in CNC turning and manual lathe operations.\u003c\/p\u003e\u003cp\u003eThis insert is suited for external NPT tapered pipe thread cutting in both job shop and production-floor environments. The IC908 grade with PVD TiAlN coating supports use across universal workpiece material categories, including steels, stainless alloys, cast irons, non-ferrous metals, and high-temperature alloys. The M chipbreaker geometry supports stable chip control across these material groups. Typical applications include threading pipe fittings, nipples, couplings, and other components requiring NPT-standard tapered external threads.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with IC908 grade for high wear resistance\u003c\/li\u003e\n\u003cli\u003ePVD-applied TiAlN coating supports extended tool life across universal material grades\u003c\/li\u003e\n\u003cli\u003e14 TPI pitch conforms to NPT tapered pipe thread standard\u003c\/li\u003e\n\u003cli\u003eRight-hand external thread orientation for standard NPT pipe thread cutting\u003c\/li\u003e\n\u003cli\u003eM chipbreaker geometry for controlled chip evacuation\u003c\/li\u003e\n\u003cli\u003e3\/8 inch inscribed circle with 16ER insert style for broad toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 16ER-profile threading toolholders compatible with laydown-style inserts.

Ensure the machine spindle is fully stopped and the toolholder is secured before seating or removing the insert. Inspect the insert pocket and clamping screw for wear or damage before each installation. Follow the toolholder manufacturer's clamping torque guidance and do not overtighten the retention screw.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: C1, C2, C6, C7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPT\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: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 14 TPI\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: 0.05 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Finish\u003c\/strong\u003e: TiAlN Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Universal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ISO 13399\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\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: 5901573\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51748260512050,"sku":"5901573","price":150.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9dbc65f31c5b7d0d9ddf07a4e004c325.jpg?v=1788891316","url":"https:\/\/voomisupply.com\/products\/iscar-5901573-threading-insert-14-tpi-npt-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
