Part of the Snap-Tap series, it carries the CP500 manufacturer grade and features a PVD-applied TiAlN\/TiN finish for extended tool life across a wide range of workpiece materials. The insert has a 3\/8 inch inscribed circle, a thickness of 0.1366 inches, and a 0.0020 inch corner radius. The 60-degree included angle conforms to standard NPTF thread form geometry. Licensed machinists and CNC lathe operators use this insert in production and maintenance threading applications where consistent, leak-resistant pipe thread profiles are required.\u003c\/p\u003e\u003cp\u003eThis insert is suited for external NPTF tapered pipe thread turning operations on lathes and turning centers. Its universal primary workpiece material rating makes it appropriate for use on cast iron, aluminum, non-ferrous metals, steel, stainless, and high-temperature alloys. The right-hand cutting orientation fits standard right-hand threading toolholders configured for laydown insert seating. It is commonly specified in fluid system component manufacturing, instrumentation fittings, and hydraulic or pneumatic connector production where NPTF thread integrity is critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eExternal NPTF thread form at 27 TPI with 60-degree included angle\u003c\/li\u003e\n\u003cli\u003eCP500 carbide grade with PVD TiAlN\/TiN coating for wear resistance across universal workpiece materials\u003c\/li\u003e\n\u003cli\u003eSnap-Tap series 16ER style laydown insert geometry\u003c\/li\u003e\n\u003cli\u003e3\/8 inch inscribed circle, 0.1366 inch thickness for consistent toolholder fit\u003c\/li\u003e\n\u003cli\u003e0.0020 inch corner radius for precise thread root form\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting orientation for standard external threading setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement for 16ER-style laydown threading insert holders configured for external NPTF thread turning applications.

Power down and lock out the machine spindle before seating or replacing any insert. Use the correct torx or hex key to the toolholder manufacturer's recommended seating procedure — do not overtighten the clamp screw. Inspect the insert pocket and clamp for chips or debris before seating the new insert to ensure proper contact and repeatability.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\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 Standard\u003c\/strong\u003e: NPTF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: External, Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 27 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 inch\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\u003eWeight\u003c\/strong\u003e: 0.12 pounds\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: 00077885\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51559421051186,"sku":"00077885","price":111.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/59c9869b09b83c8e8857039c92ffbb94.jpg?v=1786431931","url":"https:\/\/voomisupply.com\/products\/seco-00077885-threading-insert-27-tpi-nptf-carbide-cp500","provider":"Voomi Supply","version":"1.0","type":"link"}
