It cuts at 18 threads per inch with a 60-degree included angle, making it suited for unified national thread forms on a wide range of workpiece materials. The insert measures 3\/8 inches inscribed circle and 0.146 inches thick. A PVD-applied TiN coating improves wear resistance and extends tool life in production threading operations. Licensed machinists and CNC turning operators will find this insert appropriate for both ferrous and non-ferrous threading work.\u003c\/p\u003e\u003cp\u003eThis insert is intended for right-hand external thread turning on CNC lathes and manual turning centers. The 16 ER style laydown geometry seats securely in compatible ER-style toolholders. The universal primary workpiece material rating covers a broad spectrum of materials including steel, stainless, cast iron, aluminum, and exotic alloys, making this insert a practical choice for job shops and production environments running varied material types.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate for rigidity and thermal stability in threading cuts\u003c\/li\u003e\n\u003cli\u003ePVD TiN coating applied for improved wear resistance and surface finish on threaded profiles\u003c\/li\u003e\n\u003cli\u003e18 TPI cutting geometry with 60-degree included angle for UN thread forms\u003c\/li\u003e\n\u003cli\u003eRight-hand external thread orientation for standard OD threading applications\u003c\/li\u003e\n\u003cli\u003e3\/8 inch inscribed circle with 0.146 inch thickness in the 16 ER laydown style\u003c\/li\u003e\n\u003cli\u003eUniversal material compatibility rating covering steel, stainless, cast iron, aluminum, and exotic alloys\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in ER-style external threading toolholders accepting 16 ER laydown inserts.

Ensure the machine spindle is fully stopped and the toolholder is clear of the workpiece before seating or replacing the insert. Use the appropriate torque wrench and insert screw specified by the toolholder manufacturer to secure the insert without cracking the carbide. Verify thread pitch and insert orientation against the job drawing before beginning the threading pass.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: BXC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 18 TPI\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\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated (TiN)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.146 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Universal\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: 16ER18UNBXC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CARMEX","offers":[{"title":"Default Title","offer_id":52017485021490,"sku":"16ER18UNBXC","price":251.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4759c61f990209b7afe0e39f034a6aa6.jpg?v=1790009476","url":"https:\/\/voomisupply.com\/products\/carmex-16er18unbxc-threading-insert-18-tpi-3-8-inch-ic","provider":"Voomi Supply","version":"1.0","type":"link"}
