Built from micrograin solid carbide with a CP500 grade and PVD-applied TiAlN\/TiN coating, it delivers consistent edge performance across a wide range of workpiece materials. The 60-degree included angle suits standard unified thread profiles. With a 3\/8 inch inscribed circle and a thickness of 0.1366 inches, this insert fits standard laydown toolholders in the Snap Tap series. It is installed by machinists and CNC operators performing precision threading operations on lathes and turning centers in production and job shop environments.\u003c\/p\u003e\u003cp\u003eThis insert is suited for internal thread turning applications on materials classified under ISO workpiece codes K, M, N, P, and S, making it applicable across cast irons, non-ferrous metals, non-metals, steels, and heat-resistant superalloys. The right-hand cutting orientation and UN thread standard make it a practical choice for general-purpose internal threading in both low-volume job shop work and higher-volume production runs. It ships in a package quantity of one insert, with a minimum order of two units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide micrograin substrate with CP500 manufacturer grade for wear resistance\u003c\/li\u003e\n\u003cli\u003ePVD-applied TiAlN\/TiN coating for thermal and abrasion resistance\u003c\/li\u003e\n\u003cli\u003e40 TPI internal UN thread form with 60-degree included angle\u003c\/li\u003e\n\u003cli\u003eRight-hand cut orientation for standard internal threading applications\u003c\/li\u003e\n\u003cli\u003e3\/8 inch inscribed circle fits common Snap Tap series laydown toolholders\u003c\/li\u003e\n\u003cli\u003eISO-rated for universal workpiece materials including steels, cast irons, non-ferrous, and superalloys\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with laydown-style internal threading toolholders in the Snap Tap series accepting a 3\/8 inch inscribed circle insert with 16NR geometry.

Use the appropriate torx or hex key as specified by the toolholder manufacturer to secure the clamping screw to the correct seating torque per the holder documentation. Inspect the insert pocket for chips or wear before seating a new insert. Replace the insert at the first sign of chipping or thread form degradation to avoid damage to the workpiece or toolholder.\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 Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 40\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 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: 0.0020 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 Material Codes\u003c\/strong\u003e: 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\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: 00077849\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51559748763954,"sku":"00077849","price":101.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fed2199a9669a2e351dc246a801a2755.jpg?v=1786439884","url":"https:\/\/voomisupply.com\/products\/seco-00077849-threading-insert-40-tpi-3-8-in-ic-un-cp500","provider":"Voomi Supply","version":"1.0","type":"link"}
