Manufactured from solid carbide micrograin substrate with a PVD-applied TiN coating, it delivers consistent thread form and extended tool life across a wide range of workpiece materials. The insert carries a 30-degree included angle and is produced in a right-hand configuration. Measuring 0.375 inches inscribed circle and 0.146 inches thick, the 16ER geometry seats in standard 16ER toolholders. This insert is used by machinists and CNC operators in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for external NPT threading operations on materials including steel, stainless steel, cast iron, aluminum, non-ferrous metals, and high-temperature alloys, as reflected by the universal workpiece material classification. It is commonly installed in CNC lathes and manual threading setups where pipe thread form accuracy and sealing thread geometry are required. The MXC grade and micrograin carbide construction make it appropriate for both continuous and interrupted threading passes where edge toughness matters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide micrograin substrate for edge integrity and dimensional consistency\u003c\/li\u003e\n  \u003cli\u003ePVD TiN coating applied via physical vapor deposition for wear resistance and reduced friction\u003c\/li\u003e\n  \u003cli\u003e30-degree included angle for accurate NPT external thread form\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, 18 TPI for standard NPT pipe thread applications\u003c\/li\u003e\n  \u003cli\u003eUniversal material grade compatibility covering steel, stainless, cast iron, aluminum, and superalloys\u003c\/li\u003e\n  \u003cli\u003eMeets CE and ISO 13485:2016, ISO 14001:2015, and ISO 45001 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit insert for standard 16ER-style external threading toolholders used in NPT thread cutting applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or CNC tool-setup technicians. The machine spindle must be stopped and the turret or toolpost must be safely indexed before seating or removing the insert. Use the correct torx or clamping key specified for the toolholder to achieve proper clamping force without over-torquing the retention screw. Inspect the insert pocket and seating surface for chips or debris before installation to ensure accurate thread form output.\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\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: MXC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN (Coated, PVD Process)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: External\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: 18 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.375 inches (3\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.146 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Universal (H, K, M, N, P, S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: CE, ISO 13485:2016, ISO 14001:2015, ISO 45001\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: CARMEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 16ER18NPTMXC\/G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CARMEX","offers":[{"title":"Default Title","offer_id":52079156855090,"sku":"16ER18NPTMXC\/G","price":1395.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c17ba438a65346df7b67f03f13a77d7b.jpg?v=1790054590","url":"https:\/\/voomisupply.com\/products\/carmex-16er18nptmxc-g-threading-insert-18-tpi-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
