It runs at 14 threads per inch with a 60-degree included angle, making it compatible with the Unified National thread standard used throughout North American manufacturing. The insert carries a PVD-applied TiN coating under the MXC grade designation, which uses a micrograin carbide substrate for improved edge retention and heat resistance. At 0.375 inches inscribed circle and 0.146 inches thick, it seats in standard 16IR toolholders. Machinists and CNC programmers working in job shops and production environments install this insert for internal threading passes.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for right-hand internal threading operations on a wide range of workpiece materials. The universal primary workpiece material rating covers carbon steels, stainless steels, cast irons, nonferrous alloys, and heat-resistant superalloys, corresponding to ISO material groups H, K, M, N, P, and S. It is a strong general-purpose choice for shops threading UN fastener profiles in both prototype and production runs on turning equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide substrate for increased wear resistance and edge stability\u003c\/li\u003e\n  \u003cli\u003ePVD TiN coating under the MXC grade for extended tool life across varied materials\u003c\/li\u003e\n  \u003cli\u003e14 TPI UN internal thread profile with 60-degree included angle\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut geometry for standard lathe threading operations\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch inscribed circle fits standard 16IR toolholder pockets\u003c\/li\u003e\n  \u003cli\u003eUniversal material compatibility covering ISO groups H, K, M, N, P, and S\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement insert for standard 16IR internal threading toolholders used in CNC turning applications requiring UN thread forms at 14 TPI.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by CNC machinists and toolroom technicians. Before seating the insert, ensure the toolholder pocket and clamping hardware are free of chips and debris to prevent improper seating. Torque the clamping screw to the toolholder manufacturer specification using the appropriate Torx or hex key. Confirm thread profile and pitch with a thread gauge before running a full production 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\u003eThread Standard\u003c\/strong\u003e: UN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 14 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 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\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Universal (ISO Groups 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: 16IR14UNMXC\/G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CARMEX","offers":[{"title":"Default Title","offer_id":52124889579826,"sku":"16IR14UNMXC\/G","price":251.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9319effbb5a5058bf0c6052dc5c1a10c.jpg?v=1790087199","url":"https:\/\/voomisupply.com\/products\/carmex-16ir14unmxc-g-threading-insert-14-tpi-3-8-in-internal-un","provider":"Voomi Supply","version":"1.0","type":"link"}
