Manufactured to the 3ER insert style with a 3\/8 inch inscribed circle, it cuts at 8 threads per inch (TPI) with a 60-degree included angle conforming to the UN thread standard. The VTX grade features a PVD-applied TiAlN coating that resists heat and wear across a broad range of workpiece materials. Right-hand cutting geometry and the standard series profile make it a direct fit for production threading operations where consistent thread form and insert life matter.\u003c\/p\u003e\u003cp\u003eThis insert is suited for external threading on materials spanning steel, stainless, cast iron, non-ferrous alloys, and high-temperature alloys, as reflected by its universal primary workpiece material classification covering material codes H, K, M, N, P, and S. Typical applications include threading shafts, fittings, fasteners, and hydraulic components on manual or CNC turning equipment. The 3ER insert style seats in standard laydown threading toolholders, making it common in job shop and production environments where UN-standard external threads are routinely produced.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate with PVD TiAlN coating for extended tool life and heat resistance\u003c\/li\u003e\n\u003cli\u003e8 TPI cutting edge for UN-standard external threads\u003c\/li\u003e\n\u003cli\u003e60-degree included angle meets ANSI B1.1:74 thread form requirements\u003c\/li\u003e\n\u003cli\u003e3\/8 inch inscribed circle in the standard 3ER laydown insert style\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting geometry for conventional external thread turning\u003c\/li\u003e\n\u003cli\u003eUniversal material compatibility across steel, stainless, cast iron, non-ferrous, and superalloy workpieces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard laydown threading toolholders that accept the 3ER insert style.

Power down and lock out the machine spindle before changing inserts. Verify insert seating and shim condition before resuming cuts, and confirm thread pitch with a calibrated thread gauge after the first pass. Disposal of worn carbide inserts should follow local regulations for carbide and coated tooling waste.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 3ER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 8 TPI\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: 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\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: VTX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Universal (H, K, M, N, P, S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI B1.1:74, ISO 9001:2008\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.13 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: VARGUS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 51924\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VARGUS","offers":[{"title":"Default Title","offer_id":67913355755826,"sku":"51924","price":316.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9b166d6ae76faf7756b4e2e305985ab6.jpg?v=1791244736","url":"https:\/\/voomisupply.com\/products\/vargus-51924-threading-insert-8-tpi-3-8-inch-ic-un-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
