It operates at 16 threads per inch (TPI) 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 the BMA manufacturer grade with a submicron carbide substrate. The 3\/8-inch inscribed circle and 0.146-inch thickness conform to the 16ER insert style standard. Machinists and toolroom technicians working in production or job-shop turning operations install this insert into compatible 16ER-style toolholders.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for right-hand external threading across a broad range of workpiece materials. The BMA grade with PVD TiAlN coating supports cutting in universal material groups, including carbon steels, alloy steels, stainless steels, cast irons, non-ferrous metals, and heat-resistant superalloys. It is well suited for both general-purpose production threading and mixed-material job-shop environments where a single insert grade must cover varied stock. The chipbreaker style is B, which aids in chip control during threading passes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide submicron substrate for edge strength and wear resistance\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating via PVD process for thermal and oxidation resistance at the cutting edge\u003c\/li\u003e\n  \u003cli\u003e16 TPI with 60-degree included angle for standard UN external thread profiles\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting orientation for conventional external threading operations\u003c\/li\u003e\n  \u003cli\u003eB chipbreaker geometry for improved chip management during threading passes\u003c\/li\u003e\n  \u003cli\u003eUniversal material compatibility covering steels, stainless, cast iron, non-ferrous, and superalloys\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in 16ER-style laydown threading toolholders configured for right-hand external UN thread cutting at 16 TPI.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or CNC toolroom technicians. Power down and lock out the machine spindle before seating or replacing the insert. Ensure the toolholder pocket is clean and free of debris before installing the insert, and verify the clamping screw torque is consistent with the toolholder manufacturer specification. Do not use a damaged or chipped insert, as this can affect thread form accuracy and workpiece surface finish.\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\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: External\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 16\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: 0.0070 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\u003c\/strong\u003e: Universal (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: 16ERB16UNBMA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CARMEX","offers":[{"title":"Default Title","offer_id":51973905318194,"sku":"16ERB16UNBMA","price":252.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f716b39a55b2634a5a232ebdbabd0eb0.jpg?v=1789974993","url":"https:\/\/voomisupply.com\/products\/carmex-16erb16unbma-threading-insert-16-tpi-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
