Built from solid carbide in the CP500 grade, it carries a PVD-applied TiAlN\/TiN finish that extends cutting edge life in demanding threading operations. The insert follows a right-hand cutting geometry with a 60-degree included angle, fitting the 16ER insert style used in standard Snap-Tap toolholders. With a 3\/8-inch inscribed circle (IC) and a thickness of 0.1366 inches, this insert is sized for precise, repeatable thread profile generation on external workpiece features. It is sold individually with a minimum order quantity of two pieces.\u003c\/p\u003e\u003cp\u003eThis insert is intended for CNC lathes and turning centers performing external UNJ-standard threading on a broad range of workpiece materials. The CP500 grade with PVD coating is rated for universal application, covering cast iron, non-ferrous alloys, non-metals, carbon and alloy steels, and heat-resistant superalloys — reflected in material codes K, M, N, P, and S. Typical users include CNC machinists and toolroom technicians working to ISO threading standards where UNJ thread form requirements apply, such as aerospace and precision mechanical assemblies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e16ER insert style fits Snap-Tap compatible right-hand external threading toolholders\u003c\/li\u003e\n\u003cli\u003eCP500 solid carbide grade with PVD TiAlN\/TiN coating for extended tool life\u003c\/li\u003e\n\u003cli\u003e20 TPI UNJ thread form with 60-degree included angle for accurate profile generation\u003c\/li\u003e\n\u003cli\u003eUniversal material compatibility across K, M, N, P, and S workpiece material codes\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0070 inches supports clean thread root geometry\u003c\/li\u003e\n\u003cli\u003eConforms to ISO threading insert standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in 16ER-style Snap-Tap external threading toolholders that accept laydown inserts with a 3\/8-inch inscribed circle.

Power down and de-energize the machine before seating or replacing inserts. Use the appropriate torx or hex key to secure the insert clamp to the manufacturer-specified feel — do not overtighten by feel alone; follow the toolholder manufacturer torque guidance. Inspect the insert seat and clamp for chips or debris before mounting to ensure full, flat insert contact.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 16ER\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\u003eCoating\u003c\/strong\u003e: TiAlN\/TiN (PVD Process)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNJ\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: External\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 20 TPI\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\u003eInscribed Circle\u003c\/strong\u003e: 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: 0.0070 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\u003eStandard\u003c\/strong\u003e: ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 piece per package\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\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291804\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: 00049917\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558286164274,"sku":"00049917","price":109.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e6b99e033a339a7dfd3c1641f0eddca7.jpg?v=1786408532","url":"https:\/\/voomisupply.com\/products\/seco-00049917-threading-insert-20-tpi-unj-carbide-cp500","provider":"Voomi Supply","version":"1.0","type":"link"}
