Manufactured from submicron-grade carbide and finished with a PVD-applied TiAlN coating, this insert delivers consistent thread form in a wide range of workpiece materials. It carries a 3\/8 inch (0.375 inch) inscribed circle, a thickness of 0.146 inches, and a 60-degree included angle standard to Unified National thread profiles. Licensed machinists and CNC tool setup technicians typically specify this insert for precision external threading operations on lathes and turning centers.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for external UN threading applications across a broad material spectrum, including steel, stainless steel, cast iron, non-ferrous alloys, and high-temperature alloys, reflected in its H, K, M, N, P, and S workpiece material codes. It is appropriate for both production and job-shop environments where repeatable thread quality and long tool life are required. The TiAlN PVD coating supports dry or minimal-lubrication cutting conditions and helps resist heat buildup at the cutting edge during continuous threading passes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid submicron carbide substrate for high wear resistance and edge stability\u003c\/li\u003e\n  \u003cli\u003ePVD TiAlN coating supports elevated cutting temperatures and extends insert life\u003c\/li\u003e\n  \u003cli\u003e16 TPI, 60-degree included angle for standard Unified National external thread form\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch inscribed circle (0.375 inch) with 0.146 inch thickness for laydown-style toolholders\u003c\/li\u003e\n  \u003cli\u003e0.007 inch corner radius for controlled thread root geometry\u003c\/li\u003e\n  \u003cli\u003eUniversal material grade rating covers steel, stainless, cast iron, non-ferrous, and superalloys\u003c\/li\u003e\n  \u003cli\u003eManufactured to 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 application insert for laydown-style external threading toolholders accepting the 16 ER insert style and a 3\/8 inch inscribed circle seating geometry.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and indexing should be performed by a qualified machinist or CNC tooling technician. Always power down and lock out the machine before seating or indexing the insert. Use the correct torque wrench and manufacturer-specified clamping screw to secure the insert in the toolholder  -  do not overtighten by hand. Confirm thread pitch and insert orientation match the programmed toolpath before resuming cutting operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 16 ER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 16\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, Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 16 TPI\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\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\u003eInsert Material\u003c\/strong\u003e: Solid Carbide, Submicron Grade\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 Process\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: 16ER16UNBMA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CARMEX","offers":[{"title":"Default Title","offer_id":51972343267634,"sku":"16ER16UNBMA","price":288.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6a660a50ed6243ae29e5c678cb3e10ce.jpg?v=1789966560","url":"https:\/\/voomisupply.com\/products\/carmex-16er16unbma-threading-insert-16-tpi-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
