It carries a TiN (titanium nitride) coating applied via PVD process, which improves surface hardness and wear resistance during threading operations. The insert features a 60-degree included angle, a 3\/8 inch inscribed circle, and a thickness of 0.146 inches. It is configured for right-hand external threading and fits standard ER-style insert pockets on CNC lathes and turning centers. This insert is specified for use by machinists and tooling technicians running production or job-shop threading passes.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for external UN thread profiles at 16 TPI on CNC turning equipment in both production and repair environments. The P25C grade with TiN coating covers a broad range of workpiece materials, making it viable across steel, cast iron, non-ferrous metals, high-temp alloys, and stainless steel applications. It is commonly used in shops producing threaded shafts, fasteners, and fittings where consistent thread form and tool life are critical. Minimum order quantity is 10 pieces; package quantity is 1.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLaydown insert style with 16 ER designation for compatibility with standard ER-style toolholders\u003c\/li\u003e\n  \u003cli\u003e16 TPI UN external thread form with 60-degree included angle\u003c\/li\u003e\n  \u003cli\u003eSolid carbide substrate at manufacturer grade P25C for broad material coverage\u003c\/li\u003e\n  \u003cli\u003ePVD-applied TiN coating for enhanced wear resistance and surface hardness\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting configuration\u003c\/li\u003e\n  \u003cli\u003eCertified 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 for use in ER-style laydown threading insert pockets on CNC lathes and turning centers capable of external UN thread cutting.

Power down and lock out the machine spindle before seating or replacing inserts. Use the correct torx or clamp screw driver specified for the toolholder to avoid damaging the insert pocket or seating surface. Verify thread form and pitch with a thread gauge after the first pass before committing to full production run.\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 Laydown\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 16\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\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 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.146 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\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: P25C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN\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 Code\u003c\/strong\u003e: H; K; M; N; P; S\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  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291804\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: 3\/8EXRH16UNP2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CARMEX","offers":[{"title":"Default Title","offer_id":52042434937138,"sku":"3\/8EXRH16UNP2","price":252.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/05636091dec2a3d3aa32e0939ea28819.jpg?v=1790028449","url":"https:\/\/voomisupply.com\/products\/carmex-3-8exrh16unp2-threading-insert-16-tpi-un-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
