Built from micrograin solid carbide with a TiAlN\/TiN PVD coating, this insert delivers consistent thread form and edge retention when cutting internal unified national (UN) thread profiles at 12 threads per inch (TPI). The 60-degree included angle conforms to standard UN thread geometry. The A2 chipbreaker geometry promotes controlled chip evacuation in blind and through-hole applications. Licensed HVAC, plumbing, and mechanical trade professionals working in precision machining environments will recognize the CP500 grade as optimized for demanding cutting conditions.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for internal threading applications where stainless steel is the primary workpiece material (ISO material code M). The Snap Tap series designation indicates compatibility with laydown-style toolholders accepting 16NR-profile inserts. Typical install scenarios include CNC lathes and manual turning centers performing single-point threading passes on stainless steel components such as fittings, couplings, and valve bodies. The right-hand cutting orientation and 3\/8-inch inscribed circle fit a common range of internal threading toolholder bores.\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 extended tool life in stainless steel\u003c\/li\u003e\n  \u003cli\u003e12 TPI UN internal thread form with 60-degree included angle\u003c\/li\u003e\n  \u003cli\u003eA2 chipbreaker geometry for controlled chip management in internal bores\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting orientation for standard internal threading passes\u003c\/li\u003e\n  \u003cli\u003eCP500 manufacturer grade rated for ISO M workpiece materials (stainless steel)\u003c\/li\u003e\n  \u003cli\u003eConforms to ISO standards for insert geometry and dimensional tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with laydown-style internal threading toolholders accepting the 16NR insert profile.

Power down and lock out the machine spindle before seating or replacing the insert. Ensure the toolholder pocket is clean and free of chips before seating the insert to maintain proper seating depth and thread form accuracy. Minimum order quantity for this insert is 2 pieces; individual packages contain 1 insert.\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 (Internal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 12 TPI\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: 0.3750 inches (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: 0.0060 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\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\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: 00077979\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51557757387058,"sku":"00077979","price":82.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2c0d9147e1101baab9c5a600ba571b94.jpg?v=1786394339","url":"https:\/\/voomisupply.com\/products\/seco-00077979-threading-insert-12-tpi-un-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
