It cuts at 12 threads per inch with a 60-degree included angle, making it suited for standard Unified National thread profiles. The insert features a TiAlN coating applied via PVD process and carries a BMA manufacturer grade built on a submicron carbide substrate. With an inscribed circle of 0.375 inches and a thickness of 0.146 inches, the 16ER style insert seats into compatible laydown-style toolholders. Right-hand cutting orientation is standard. Installation is performed by qualified CNC machinists or tool-and-die professionals.\u003c\/p\u003e\u003cp\u003eThis insert is intended for external threading operations on a broad range of workpiece materials. The universal primary workpiece material designation covers ferrous and non-ferrous metals including carbon steels, stainless steels, cast irons, aluminum alloys, titanium, and superalloys, as reflected by the H, K, M, N, P, and S material codes. It is commonly used in production turning environments where consistent thread form and tool life across mixed-material runs are required. The B chipbreaker geometry supports chip control during threading passes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide submicron substrate for wear resistance and edge stability\u003c\/li\u003e\n\u003cli\u003eTiAlN coating via PVD process for extended tool life in demanding materials\u003c\/li\u003e\n\u003cli\u003e60-degree included angle for standard UN external thread profiles\u003c\/li\u003e\n\u003cli\u003e12 TPI cutting capability with right-hand orientation\u003c\/li\u003e\n\u003cli\u003eB chipbreaker for improved chip control during threading\u003c\/li\u003e\n\u003cli\u003eUniversal material compatibility across H, K, M, N, P, and S workpiece classifications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in 16ER-style laydown threading toolholders accepting inserts with a 0.375-inch inscribed circle and 0.146-inch thickness in standard UN external thread applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist with the machine powered off and all axes locked before insert exchange. Use the correct torque wrench and clamping screw specified by the toolholder manufacturer to secure the insert without over-tightening. Verify thread pitch and hand orientation match the programmed toolpath before resuming cutting operations. Inspect the insert seat and pocket for debris or damage before seating a new insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 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 (Unified National)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: External\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 12\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: 3\/8 inch (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: 0.0100 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\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 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\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: 16ERB12UNBMA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CARMEX","offers":[{"title":"Default Title","offer_id":52041150398770,"sku":"16ERB12UNBMA","price":289.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f716b39a55b2634a5a232ebdbabd0eb0_80d1b36e-2cea-4d92-9fdf-f0702ffc4666.jpg?v=1790027558","url":"https:\/\/voomisupply.com\/products\/carmex-16erb12unbma-threading-insert-12-tpi-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
