Built from solid carbide micrograin substrate in the CP500 grade, it carries a PVD-applied TiAlN\/TiN coating for extended tool life when threading cast iron, stainless steel, and carbon steel. The insert features a 16NR style with a 3\/8 inch inscribed circle and a nominal thickness of 0.1366 inches. It belongs to the Snap Tap series and is suited for CNC turning centers and lathes where precise, repeatable thread forms are required. Installation and toolpath setup is handled by machinists and CNC operators on the shop floor.\u003c\/p\u003e\u003cp\u003eThis insert is intended for internal UN threading operations on a range of workpiece materials including cast iron (ISO K), stainless steel (ISO M), and steel (ISO P). The A1 chipbreaker geometry is selected for controlled chip flow during threading passes. The 60-degree included angle matches the standard UN thread form. Typical applications include threading bores in production machining environments where consistent thread quality across high-volume runs is a priority.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide micrograin substrate in CP500 grade for hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003ePVD TiAlN\/TiN coating extends cutting life across multiple workpiece material groups\u003c\/li\u003e\n\u003cli\u003e20 TPI, 60-degree included angle for standard UN internal thread form\u003c\/li\u003e\n\u003cli\u003eA1 chipbreaker geometry for controlled chip evacuation during threading passes\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting orientation with 3\/8 inch inscribed circle and 0.1366 inch thickness\u003c\/li\u003e\n\u003cli\u003eISO-standard insert geometry for use in compatible 16NR toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in 16NR-style toolholders compatible with the Snap Tap series.

Power down and lock out the machine spindle before seating or removing inserts. Use the appropriate torx or clamping key specified for the toolholder to secure the insert without over-torquing the clamping screw. Verify insert seating and thread form with a thread gauge after the first pass before committing to a full production run.\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\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: CP500\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\/TiN, PVD Applied\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\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 20\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\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 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: 0.0040 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge to Theoretical Edge Length\u003c\/strong\u003e: 0.0310 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFace of Insert to Tip Centerline\u003c\/strong\u003e: 0.0310 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\u003eISO Material Codes\u003c\/strong\u003e: K, M, P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Snap Tap\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\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 pounds\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: 00064716\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51559419445554,"sku":"00064716","price":82.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2058262384c79506274aa6186001b5d5.jpg?v=1786431874","url":"https:\/\/voomisupply.com\/products\/seco-00064716-threading-insert-20-tpi-3-8-ic-un-cp500","provider":"Voomi Supply","version":"1.0","type":"link"}
