Manufactured in the 3ER insert style with a 3\/8-inch inscribed circle, this insert features a 60-degree included angle and a PVD-applied titanium nitride (TiN) coating. The VKX manufacturer grade and TiN finish work together to extend tool life across a broad range of workpiece materials. Right-hand orientation makes it suitable for standard external threading operations on CNC lathes and screw machines. The insert is a direct-fit replacement for OEM-style 3ER toolholders used in production threading applications.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for external UN threading on turning centers, CNC lathes, and manual lathes equipped with compatible 3ER-style toolholders. The universal primary workpiece material designation covers a wide range of materials including steels, stainless steels, cast irons, non-ferrous alloys, high-temperature alloys, and hardened materials. Machinists and toolroom technicians working in job shop, production, or maintenance environments will find this insert suited for threading fastener profiles, fittings, and other externally threaded components to UN standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3ER insert style with 3\/8-inch inscribed circle for direct toolholder compatibility\u003c\/li\u003e\n  \u003cli\u003e13 TPI UN external thread form with 60-degree included angle\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003ePVD TiN coating for extended edge life across universal workpiece materials\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting orientation for standard external threading\u003c\/li\u003e\n  \u003cli\u003eISO 9001:2008 manufactured under certified quality standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement laydown threading insert for 3ER-style external threading toolholders used in UN thread applications at 13 TPI.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine before indexing or replacing inserts. Use the appropriate torque wrench and insert clamping screws specified by the toolholder manufacturer  -  do not overtighten, as carbide inserts are brittle and susceptible to clamp-induced fracture. Verify insert seating and toolholder cleanliness before resuming cutting operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: VKX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 13 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: UN\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\u003eCoating\/Finish\u003c\/strong\u003e: TiN\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\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO 9001:2008\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: VARGUS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 51310\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VARGUS","offers":[{"title":"Default Title","offer_id":67907312615730,"sku":"51310","price":314.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/22c6a74276be6b56ff48841297e828a7.jpg?v=1791176890","url":"https:\/\/voomisupply.com\/products\/vargus-51310-threading-insert-13-tpi-3-8-inch-un-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
