Manufactured from solid carbide with a PVD-applied TiAlN coating, this insert delivers the hardness and thermal resistance needed for consistent thread form across a wide range of workpiece materials. It cuts right-hand external threads at 18 threads per inch with a 60-degree included angle, conforming to the UNJ thread standard. The 3ER insert style features a 9.53 mm inscribed circle and a thickness of 3.60 mm. Machinists and CNC operators install this insert when producing UNJ threads required for aerospace and high-cycle fastener applications.\u003c\/p\u003e\n\u003cp\u003eThis insert is rated for universal workpiece material compatibility, covering material groups H, K, M, N, P, and S  -  meaning it handles carbon steels, alloy steels, stainless steels, cast irons, non-ferrous metals, and high-temperature superalloys. It is suited for production threading in both job-shop and high-volume manufacturing environments where UNJ thread profiles are specified. The VTX manufacturer grade is a VARGUS designation indicating the insert geometry and substrate selection for this product line. This insert ships individually but carries a minimum order quantity of 10 units per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with PVD TiAlN coating for high wear resistance and thermal stability\u003c\/li\u003e\n  \u003cli\u003eCuts UNJ external threads at 18 TPI with a 60-degree included angle\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, 3ER insert style with 9.53 mm inscribed circle\u003c\/li\u003e\n  \u003cli\u003eCompatible with material groups H, K, M, N, P, and S for broad workpiece versatility\u003c\/li\u003e\n  \u003cli\u003eMeets MIL-S-8879C and ISO 9001:2008 standards\u003c\/li\u003e\n  \u003cli\u003eStandard series insert geometry for laydown toolholder seating\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement laydown threading insert for 3ER-style toolholders requiring an 18 TPI UNJ external thread profile.

Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque wrench and clamp screw specified by the toolholder manufacturer  -  do not overtighten, as carbide inserts are brittle under bending loads. Verify insert seating and thread form with a first-article thread gauge before running production.\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: VTX\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\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 18\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: 9.53 mm (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3.60 mm\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 Groups\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: 0.8 pounds\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: 51495\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VARGUS","offers":[{"title":"Default Title","offer_id":67916158828850,"sku":"51495","price":322.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f713f09d129293ba4eb8c205c710a302_8ba367b7-59f1-4d1d-b106-9ffbd81e558a.jpg?v=1791256085","url":"https:\/\/voomisupply.com\/products\/vargus-51495-threading-insert-18-tpi-unj-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
