Part of the Snap-Tap series, this insert is manufactured from solid carbide in the CP500 grade and features a TiAlN\/TiN PVD coating for extended tool life across a wide range of workpiece materials. The 16ER insert style has a 3\/8 inch inscribed circle and a thickness of 0.1366 inches. The 60-degree included angle and right-hand cutting geometry make this insert suited for precision external threading operations on CNC lathes and turning centers.\u003c\/p\u003e\n\u003cp\u003eThis insert is used in precision machining environments where UNJ thread forms are required, including aerospace, defense, and industrial manufacturing applications. The UNJ thread standard specifies a controlled root radius, making it common in high-stress fastener and fitting applications. The CP500 carbide grade with PVD coating supports use across universal workpiece material categories including cast iron, non-ferrous metals, non-metallic materials, steel, and heat-resistant superalloys (ISO material codes K, M, N, P, S). It is installed by machinists and CNC operators on compatible laydown-style threading toolholders.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e28 TPI external UNJ thread profile with 60-degree included angle\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction in CP500 manufacturer grade\u003c\/li\u003e\n  \u003cli\u003eTiAlN\/TiN PVD coating for wear resistance and extended insert life\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting geometry in 16ER laydown insert style\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch inscribed circle with 0.1366 inch thickness\u003c\/li\u003e\n  \u003cli\u003eCompatible with universal workpiece materials per ISO codes K, M, N, P, S\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 16ER-style laydown threading toolholders that accept a 3\/8 inch inscribed circle insert.

Ensure the machine is fully powered down and the spindle is locked before changing inserts. Seat the insert fully and evenly against the toolholder pocket, and secure with the appropriate clamping screw to the torque specified by the toolholder manufacturer. Do not use damaged or chipped inserts, as this can compromise thread form accuracy and tool integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 16ER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 28 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: External\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNJ\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: 0.0060 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\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\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\u003eStandard\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  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291804\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: 00049941\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51557303025970,"sku":"00049941","price":109.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8dfeb5e83163b5e7a1fe967400f790e9.jpg?v=1786385479","url":"https:\/\/voomisupply.com\/products\/seco-00049941-threading-insert-28-tpi-unj-carbide-cp500","provider":"Voomi Supply","version":"1.0","type":"link"}
