Manufactured from solid carbide micrograin substrate in the CP500 grade with a PVD-applied TiAlN\/TiN coating, this insert delivers consistent edge life across a range of workpiece materials. It cuts right-hand threads at 18 threads per inch with a 60-degree included angle, producing the tapered NPTF thread form required for pressure-tight pipe connections without the need for sealant. The insert seats in standard 16ER-style laydown toolholders and is suited for shops running production threading operations on pipe fittings, couplings, and similar components.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for external NPTF threading applications in metalworking environments. The CP500 micrograin carbide grade with PVD coating makes it suitable for threading across universal workpiece material categories including cast iron, non-ferrous metals, non-metals, steel, and heat-resistant super alloys. Typical applications include threading 3\/8-inch pipe ends and similar small-diameter NPTF connections in manufacturing, maintenance, and job-shop settings. It is part of the Snap Tap series and conforms to ISO insert standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide micrograin substrate for rigidity and edge retention during threading\u003c\/li\u003e\n  \u003cli\u003eCP500 grade with PVD TiAlN\/TiN coating for extended tool life across universal workpiece materials\u003c\/li\u003e\n  \u003cli\u003eCuts right-hand external NPTF threads at 18 TPI with a 60-degree included angle\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch inscribed circle and 0.1366-inch thickness for 16ER-style toolholder compatibility\u003c\/li\u003e\n  \u003cli\u003eTapered NPTF thread form produces pressure-tight connections without sealant\u003c\/li\u003e\n  \u003cli\u003eISO-conforming insert geometry for consistent seating and repeatability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in 16ER-style laydown threading toolholders.

Power down and lock out the machine before indexing or replacing inserts. Seat the insert fully and confirm the clamp torque is within the toolholder manufacturer's specification before resuming cuts. Do not run the insert beyond visible edge wear, as a degraded cutting edge will produce out-of-tolerance thread forms on pressure-critical NPTF connections.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 16ER\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\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 Coated)\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: NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 18\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 (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: 0.0020 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Universal (K, M, N, P, S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Snap Tap\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO\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\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 00077866\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51564080922930,"sku":"00077866","price":111.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/523b3b14c51bc31062765e7a0cc2ac5e.jpg?v=1786510441","url":"https:\/\/voomisupply.com\/products\/seco-00077866-threading-insert-18-tpi-nptf-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
