Built from micrograin solid carbide with a PVD-applied TiAlN\/TiN coating, this insert carries the CP500 manufacturer grade and A2 chipbreaker geometry. The 60-degree included angle conforms to UN thread form standards, and the 3\/8-inch inscribed circle suits a wide range of standard toolholders. Licensed machinists and CNC lathe operators working in production threading applications will find this insert suited to demanding internal threading cycles, particularly in stainless steel and other ISO M-group workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThis insert is designed for internal threading operations on stainless steel (ISO material group M) and similar difficult-to-machine alloys. It belongs to SECO's Snap Tap series, which targets precision thread-form replication in both job shop and production environments. The A2 chipbreaker geometry assists with chip control during internal threading passes where chip evacuation is critical. Right-hand cutting orientation is standard for the majority of conventional CNC lathe threading cycles. Installers should verify toolholder compatibility with the 16NR insert style before ordering.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide substrate with PVD TiAlN\/TiN coating for wear resistance in stainless steel\u003c\/li\u003e\n  \u003cli\u003eCP500 grade optimized for ISO M-group workpiece materials\u003c\/li\u003e\n  \u003cli\u003eA2 chipbreaker geometry promotes chip control during internal threading\u003c\/li\u003e\n  \u003cli\u003e60-degree included angle for standard UN thread form\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch (0.3750-inch) inscribed circle for broad toolholder compatibility\u003c\/li\u003e\n  \u003cli\u003eConforms to ISO standards for threading insert geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 16NR-style internal threading toolholders in the Snap Tap series.

Power down and de-energize the machine before changing inserts. Use the appropriate torx or hex key at the manufacturer-recommended seating procedure for laydown insert styles — do not overtighten the clamping screw. Inspect the toolholder pocket for chips or damage before seating the insert to ensure proper form contact and thread accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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)\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\u003eThreads Per Inch\u003c\/strong\u003e: 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\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: A2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Snap Tap\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: 0.0100 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge to Theoretical Edge Length\u003c\/strong\u003e: 0.0470 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFace of Insert to Tip Centerline\u003c\/strong\u003e: 0.0590 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel (ISO M)\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: 00077977\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558523568434,"sku":"00077977","price":92.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9759725cbf6448f333e102586775775d.jpg?v=1786414319","url":"https:\/\/voomisupply.com\/products\/seco-00077977-threading-insert-8-tpi-3-8-in-ic-un","provider":"Voomi Supply","version":"1.0","type":"link"}
