Manufactured from solid carbide in the CP500 grade and finished with a PVD-applied TiAlN\/TiN coating, this insert delivers wear resistance across a broad range of workpiece materials. It carries a 16NR insert style designation and is configured for right-hand cutting with an 8 threads per inch (TPI) pitch and a 60-degree included angle. The 3\/8-inch inscribed circle and 0.1366-inch thickness conform to standard Snap-Tap series toolholder pockets. Licensed machinists and CNC operators use this insert in both production and job-shop threading applications.\u003c\/p\u003e\u003cp\u003eThis insert is suited for internal NPT thread-form cutting on universal workpiece materials, including cast iron, steel, stainless, aluminum, and high-temp alloys, reflected by its K, M, N, P, and S material codes. The NPT thread standard makes it appropriate for producing tapered pipe threads used in fluid and gas line fittings across plumbing, HVAC, and industrial piping applications. The TiAlN\/TiN PVD coating extends tool life at elevated cutting speeds without coolant, though flood coolant is also compatible. This insert meets ISO standards and is classified under UNSPSC code 23291804.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide CP500 grade for consistent edge retention and dimensional stability\u003c\/li\u003e\n\u003cli\u003ePVD TiAlN\/TiN coating extends tool life across universal workpiece materials\u003c\/li\u003e\n\u003cli\u003eRight-hand internal NPT thread form at 8 TPI with 60-degree included angle\u003c\/li\u003e\n\u003cli\u003e3\/8-inch inscribed circle fits standard 16NR Snap-Tap series toolholders\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0040 inches supports clean thread-form engagement\u003c\/li\u003e\n\u003cli\u003eISO-compliant geometry for predictable performance in tight-tolerance threading\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement insert for 16NR-style Snap-Tap series threading toolholders that accept a 3\/8-inch inscribed circle laydown insert with 0.1366-inch thickness.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis insert is installed and indexed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before seating or replacing inserts. Use the appropriate insert screw torque driver per the toolholder manufacturer's specification — do not overtighten by hand. Verify thread-form alignment and pitch with a thread gauge after the first pass before running full production.\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 (PVD Process)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 8 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\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: 0.1366 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: 0.0430 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFace of Insert to Tip Centerline\u003c\/strong\u003e: 0.0630 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Snap-Tap\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Codes\u003c\/strong\u003e: K, M, N, P, S (Universal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO\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\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291804\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: 00064738\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51564027314482,"sku":"00064738","price":111.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d0f957fbdd9036978603890a2b88beec.jpg?v=1786509139","url":"https:\/\/voomisupply.com\/products\/seco-00064738-threading-insert-8-tpi-npt-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
