Manufactured from submicron-grade carbide and finished with a PVD-applied TiAlN coating, this insert delivers consistent thread form and extended tool life across a wide range of workpiece materials. The 60-degree included angle conforms to standard Unified National thread geometry. With a 3\/8-inch (0.3750-inch) inscribed circle and a 0.1460-inch thickness, it seats securely in compatible laydown-style toolholders. Right-hand cutting orientation suits the majority of standard internal threading operations on CNC lathes and turning centers.\u003c\/p\u003e\u003cp\u003eThis insert is suited for internal threading applications in production and job-shop environments running CNC turning equipment. The universal material grade designation covers a broad spectrum of workpiece materials including cast iron, non-ferrous alloys, stainless steel, steel, and heat-resistant superalloys, corresponding to ISO material groups H, K, M, N, P, and S. It is appropriate for both high-volume production threading and lower-volume precision work where consistent thread profile and surface finish are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid submicron carbide substrate for wear resistance and edge stability\u003c\/li\u003e\n\u003cli\u003ePVD TiAlN coating for reduced heat buildup and extended insert life\u003c\/li\u003e\n\u003cli\u003e14 TPI internal UN thread form with 60-degree included angle\u003c\/li\u003e\n\u003cli\u003e3\/8-inch inscribed circle (0.3750 inches) for secure laydown-style seating\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting orientation for standard internal threading setups\u003c\/li\u003e\n\u003cli\u003eUniversal primary workpiece material compatibility across ISO groups H, K, M, N, P, and S\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in laydown-style internal threading toolholders accepting a 16IR insert style with a 3\/8-inch inscribed circle.

Power down and lock out the machine before changing inserts. Use the correct torque wrench and manufacturer-specified clamping screw to seat the insert without over-torquing, which can crack carbide. Verify insert orientation and tool stick-out before resuming threading cycles, and confirm thread pitch and hand match the programmed toolpath.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eMaterial Grade\u003c\/strong\u003e: Submicron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: BMA\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1460 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0040 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN (PVD Coated)\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\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1239 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: CARMEX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 16IR14UNBMA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CARMEX","offers":[{"title":"Default Title","offer_id":52081492787506,"sku":"16IR14UNBMA","price":252.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/63ca794d0b4797feaf464abcf9c4c103.jpg?v=1790056256","url":"https:\/\/voomisupply.com\/products\/carmex-16ir14unbma-threading-insert-14-tpi-3-8-in-ic","provider":"Voomi Supply","version":"1.0","type":"link"}
