Finished with a PVD-applied TiAlN coating, it delivers extended tool life across a broad range of workpiece materials. The insert features a 3\/8-inch inscribed circle (0.3750 inches) and a thickness of 0.1460 inches, with a 60-degree included angle and a 0.0100-inch corner radius. It is sized to the 16ER style and manufactured to a submicron BMA grade, making it well-suited for precision threading operations in production environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is used in CNC lathes and turning centers performing external UN-thread operations on a wide variety of materials, including steel, stainless steel, cast iron, non-ferrous metals, and high-temperature alloys. The universal material grade designation covers workpiece material codes H, K, M, N, P, and S, giving machinists and tool-and-die shops flexibility across job types. It is a single-piece insert sold individually, with a minimum order quantity of 10 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide submicron BMA grade construction for consistent cutting performance\u003c\/li\u003e\n  \u003cli\u003ePVD TiAlN coating extends wear resistance across diverse workpiece materials\u003c\/li\u003e\n  \u003cli\u003eRight-hand external UN thread profile at 12 TPI with 60-degree included angle\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch inscribed circle (0.3750 inches) and 0.1460-inch thickness for 16ER-style holders\u003c\/li\u003e\n  \u003cli\u003e0.0100-inch corner radius for controlled thread form accuracy\u003c\/li\u003e\n  \u003cli\u003eMeets CE, 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 16ER-style laydown threading insert holders used in external UN thread turning applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or toolroom technicians on CNC or manual lathes. Ensure the machine is powered down and the spindle is fully stopped before changing inserts. Seat the insert fully and evenly in the holder pocket and secure the clamping screw to the tool manufacturer's specified torque using a calibrated torque wrench. Inspect the insert seat and clamp for wear or debris before each insert change to maintain proper seating and thread-form accuracy.\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\u003eManufacturer Grade\u003c\/strong\u003e: BMA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Submicron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 12\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: UN\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 (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0100 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1460 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 Codes\u003c\/strong\u003e: H, K, M, N, P, S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1239 pounds\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: 16ER12UNBMA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CARMEX","offers":[{"title":"Default Title","offer_id":52064117063986,"sku":"16ER12UNBMA","price":287.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/62661a1b4053f59f937c6553ee346a3d.jpg?v=1790043820","url":"https:\/\/voomisupply.com\/products\/carmex-16er12unbma-threading-insert-12-tpi-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
