Manufactured from solid carbide in the CP500 grade with micrograin structure, it carries a PVD-applied TiAlN\/TiN coating for extended tool life across a wide range of workpiece materials. The insert follows the 16NL style with an inscribed circle of 0.3750 inches and a thickness of 0.1366 inches. It cuts at 8 threads per inch with a 60-degree included angle and is configured for left-hand internal threading. This insert suits machinists and toolroom technicians running precision threading operations on lathes equipped with Snap Tap toolholders.\u003c\/p\u003e\u003cp\u003eThis insert is suited for internal UN thread profiles in both production and job-shop environments. It is a left-hand insert, making it appropriate for threading operations where the spindle or feed direction requires a left-hand cutting geometry. The CP500 grade with universal material coding covers cast iron, steel, nonferrous metals, stainless, and high-temperature alloys, making it a versatile option for shops working across multiple material categories. Packaged individually, it is a direct replacement or consumable replenishment insert for compatible 16NL Snap Tap toolholders.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with micrograin substrate for rigidity and edge strength\u003c\/li\u003e\n\u003cli\u003ePVD TiAlN\/TiN coating for heat resistance and extended wear life\u003c\/li\u003e\n\u003cli\u003e8 TPI cutting geometry with 60-degree included angle for standard UN thread form\u003c\/li\u003e\n\u003cli\u003eLeft-hand internal thread orientation for reverse-feed or left-hand threading setups\u003c\/li\u003e\n\u003cli\u003eUniversal material grade covers steel, cast iron, nonferrous, stainless, and superalloys\u003c\/li\u003e\n\u003cli\u003eISO-standard geometry in the 16NL insert style for use with Snap Tap toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 16NL-style Snap Tap threading toolholders.

Power down and lock out the machine before changing inserts. Use the correct torque wrench and insert screw specified by the toolholder manufacturer to avoid cracking the carbide substrate. Inspect the toolholder pocket for wear, chips, or debris before seating the insert, and confirm correct hand orientation matches the programmed feed direction before resuming operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 16NL\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\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 8\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\u003eInsert Hand\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Snap Tap\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\/TiN\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\u003eCorner Radius\u003c\/strong\u003e: 0.0100 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1366 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\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\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: 00050322\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51561551200562,"sku":"00050322","price":63.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f52ede0683acfe9b825e721912534708_bb02a569-799c-4bcc-9167-2c5da7901a91.jpg?v=1786465469","url":"https:\/\/voomisupply.com\/products\/seco-00050322-threading-insert-8-tpi-un-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
