Built from solid carbide in the CP500 grade with a micrograin substrate, it carries a PVD-applied TiAlN\/TiN coating for extended wear resistance in demanding threading applications. The insert is configured for left-hand external threads at 24 threads per inch with a 60-degree included angle, a 3\/8 inch inscribed circle, and a 0.1366 inch thickness. It seats in the Snap Tap insert series and is intended for use by machinists and CNC lathe operators requiring consistent, repeatable thread form on externally threaded workpieces.\u003c\/p\u003e\u003cp\u003eThis insert is suited for threading operations across a broad range of workpiece materials, including cast iron, non-ferrous alloys, aluminum, steel, and heat-resistant alloys, consistent with the universal material compatibility codes assigned to this grade. It is a left-hand insert and is appropriate for situations where left-hand thread forms are required, such as reverse-threaded fastener applications or specific machine components. The 16EL style and size code 16 determine the compatible toolholder pocket geometry on CNC and manual turning centers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with micrograin substrate for rigidity and edge integrity\u003c\/li\u003e\n\u003cli\u003eCP500 grade with PVD TiAlN\/TiN coating for heat and wear resistance\u003c\/li\u003e\n\u003cli\u003e24 TPI left-hand external UN thread form with 60-degree included angle\u003c\/li\u003e\n\u003cli\u003e3\/8 inch inscribed circle fits standard 16EL-style Snap Tap toolholders\u003c\/li\u003e\n\u003cli\u003eUniversal workpiece material compatibility covers steel, cast iron, non-ferrous, and superalloys\u003c\/li\u003e\n\u003cli\u003eISO-standard insert geometry for consistent, verifiable thread profiles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in toolholders accepting the 16EL insert style with a size code 16 pocket geometry, as part of the SECO Snap Tap threading system.

Confirm the toolholder is designed for left-hand inserts before installation, as left-hand and right-hand inserts are not interchangeable. Power down and lock out the machine spindle before seating or removing any insert. Verify thread form and pitch with a calibrated thread gauge after the first pass.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 16EL\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\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\/TiN PVD Coated\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: External\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 24\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 (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: 0.0050 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Snap Tap\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\u003eCoating Process\u003c\/strong\u003e: PVD\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\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: 00046743\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51557918834994,"sku":"00046743","price":57.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/79e575cdeb8c06d35b75572cc088cff3_374ed03a-befa-4a89-80f0-efffff75d8f1.jpg?v=1786398352","url":"https:\/\/voomisupply.com\/products\/seco-00046743-threading-insert-24-tpi-lh-un-solid-carbide-cp500","provider":"Voomi Supply","version":"1.0","type":"link"}
