Manufactured from micrograin solid carbide in the VTX grade, this insert carries a TiAlN PVD coating that extends cutting life across a broad range of workpiece materials. The 3ER insert style produces a 60-degree UNJ thread form at 12 threads per inch on right-hand external profiles. The inscribed circle measures 0.375 inches with a thickness of 3.6 millimeters (approximately 0.142 inches). Licensed machinists and CNC programmers working in aerospace, defense, and precision manufacturing rely on this insert for controlled, repeatable thread form accuracy where MIL-S-8879C compliance is required.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for external UNJ thread turning applications across a wide variety of workpiece materials, including carbon steels, stainless steels, cast iron, non-ferrous metals, high-temperature alloys, and titanium alloys. The universal material grade designation covers material codes H, K, M, N, P, and S, making it appropriate for multi-material production environments. Typical use cases include aerospace fastener threads, hydraulic fittings, and precision shaft threading where UNJ root geometry is specified to reduce fatigue failure risk.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide VTX grade for high hardness and wear resistance at elevated cutting temperatures\u003c\/li\u003e\n  \u003cli\u003eTiAlN PVD coating extends tool life and supports dry or minimal-lubrication cutting\u003c\/li\u003e\n  \u003cli\u003e3ER insert style with 60-degree included angle for standard UNJ external thread forms\u003c\/li\u003e\n  \u003cli\u003e12 TPI right-hand thread profile with a single tooth per side for precise form control\u003c\/li\u003e\n  \u003cli\u003eMeets ISO 9001:2008 and MIL-S-8879C standards for quality and thread form compliance\u003c\/li\u003e\n  \u003cli\u003eUniversal material grade compatibility across steel, stainless, cast iron, non-ferrous, and superalloy workpieces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a laydown threading insert compatible with toolholders accepting the 3ER insert style.

Ensure the machine spindle is fully stopped and all axes are in a safe position before indexing or replacing inserts. Use the correct torque driver or clamping screw as specified by the toolholder manufacturer to secure the insert without cracking the carbide substrate. Verify thread form accuracy with thread gauges after first-article cuts before proceeding with production runs.\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\u003eThread Standard\u003c\/strong\u003e: UNJ External\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 12 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: 0.375 inches (9.53 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3.6 mm (approximately 0.142 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin VTX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\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 Codes\u003c\/strong\u003e: H, K, M, N, P, S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Teeth Per Side\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO 9001:2008, MIL-S-8879C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\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: 51272\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VARGUS","offers":[{"title":"Default Title","offer_id":67912049197362,"sku":"51272","price":314.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f713f09d129293ba4eb8c205c710a302_2924018a-16cb-4a41-aa23-6fa74b07e839.jpg?v=1791226071","url":"https:\/\/voomisupply.com\/products\/vargus-51272-3er-12-tpi-unj-threading-insert-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
