It is manufactured from solid carbide in the CP500 grade and carries a TiAlN\/TiN finish applied via PVD coating. The insert follows the 16NR style with an A1 chipbreaker geometry, a 60-degree included angle, and right-hand cutting orientation. With an inscribed circle of 0.375 inches and a thickness of 0.1366 inches, this insert seats in standard 16NR-style toolholders used for internal threading operations on CNC lathes and turning centers. Installation and operation are handled by machining professionals in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis insert is suited for internal threading applications on cast iron, stainless steel, and carbon or alloy steel workpieces. It belongs to the Snap-Tap series and conforms to ISO standards, making it a fit for shops running metric or inch-standard tooling systems. The A1 chipbreaker promotes chip control during threading passes on tough and abrasive materials. It is used in single-point threading cycles where consistent thread form and tool life are priorities across medium to high production runs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e16NR insert style with A1 chipbreaker for controlled chip evacuation during internal threading\u003c\/li\u003e\n\u003cli\u003eCP500 solid carbide grade with TiAlN\/TiN PVD coating for wear resistance on ferrous materials\u003c\/li\u003e\n\u003cli\u003e14 TPI UN thread standard, right-hand internal cutting orientation\u003c\/li\u003e\n\u003cli\u003e60-degree included angle conforms to UN thread form geometry\u003c\/li\u003e\n\u003cli\u003e0.375 inch inscribed circle and 0.1366 inch thickness for compatibility with standard 16NR toolholders\u003c\/li\u003e\n\u003cli\u003eRated for cast iron, stainless steel, and steel workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in 16NR-style internal threading toolholders.

Ensure the machine spindle is fully stopped and the toolholder is secured in the turret before seating or removing the insert. Use the appropriate torque wrench and insert screw specified by the toolholder manufacturer — do not overtighten or substitute hardware. Verify insert orientation and thread hand before initiating the threading cycle.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 16NR\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: CP500\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\/TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\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: Internal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 14\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\u003eChipbreaker\u003c\/strong\u003e: A1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Snap-Tap\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1366 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0060 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge to Theoretical Edge Length\u003c\/strong\u003e: 0.0470 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFace of Insert to Tip Centerline\u003c\/strong\u003e: 0.0590 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Stainless Steel, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291804\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SECO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 00064426\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558654148914,"sku":"00064426","price":82.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bbfc7d04bfe952834d0bb7be848cc803.jpg?v=1786417064","url":"https:\/\/voomisupply.com\/products\/seco-00064426-threading-insert-14-tpi-un-internal-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
