The insert carries a TiAlN coating applied via PVD process, providing thermal resistance and wear protection during threading operations. With a 3\/8 inch (0.375 inch) inscribed circle and a thickness of 0.146 inches, this insert fits standard laydown-style toolholders used on CNC lathes and manual turning centers. The 60-degree included angle conforms to the unified national thread form. Machinists and CNC operators in production and job-shop environments install this insert for right-hand internal thread profiles.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for threading internal UN profiles in a broad range of workpiece materials. The BMA grade uses a submicron solid carbide substrate with a PVD TiAlN finish, making it compatible with universal material groups including steel, stainless steel, cast iron, non-ferrous alloys, high-temperature alloys, and aluminum. It is appropriate for both light production runs and general-purpose threading where consistent thread form and tool life are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide submicron substrate with PVD TiAlN coating for extended tool life\u003c\/li\u003e\n  \u003cli\u003e12 TPI UN internal thread form with 60-degree included angle\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, laydown insert style for standard IR-series toolholders\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch (0.375 inch) inscribed circle for secure seating in matching pockets\u003c\/li\u003e\n  \u003cli\u003e0.005 inch corner radius for controlled thread root geometry\u003c\/li\u003e\n  \u003cli\u003eUniversal material compatibility across steel, stainless, cast iron, non-ferrous, and superalloy workpieces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a laydown-style replacement threading insert for 16IR-series internal threading toolholders accepting a 3\/8 inch inscribed circle insert.

Power down and lock out the machine spindle before changing inserts. Use the correct torque wrench or clamping screw driver specified by the toolholder manufacturer to seat the insert without cracking the carbide. Inspect the pocket for chips or debris before seating a new insert, and confirm thread direction and hand orientation match the programmed toolpath before resuming cutting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 16IR Laydown\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UN (Unified National)\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: 12\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 inch (0.375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.146 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.005 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: Submicron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: BMA\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: 0.124 pounds\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: 16IR12UNBMA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CARMEX","offers":[{"title":"Default Title","offer_id":52106781851954,"sku":"16IR12UNBMA","price":288.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/411d41e94b0c9eb7e27d38b9a4cda454.jpg?v=1790073727","url":"https:\/\/voomisupply.com\/products\/carmex-16ir12unbma-threading-insert-12-tpi-3-8-in-ic-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
