Manufactured from solid carbide with a TiN (titanium nitride) PVD coating, this insert delivers consistent thread form accuracy at 14 threads per inch (TPI) with a 60-degree included angle. The 3ER insert style seats in a standard external laydown toolholder. At 3\/8 inch inscribed circle, it is sized for common external threading applications across a wide range of workpiece materials. Machinists and toolroom technicians working to aerospace and precision standards will recognize the UNJ thread form requirement on flight-critical components.\u003c\/p\u003e\u003cp\u003eThis insert is suited for external UNJ threading operations on turning equipment in production and job-shop environments. The UNJ thread standard, governed by MIL-S-8879C, requires a controlled root radius that reduces stress concentration on threaded fasteners used in aerospace and defense applications. The VKX grade with TiN coating supports cutting across multiple workpiece material groups including steel, stainless, cast iron, non-ferrous, high-temp alloys, and aluminum, as indicated by material codes H, K, M, N, P, and S.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate with PVD TiN coating for wear resistance across diverse materials\u003c\/li\u003e\n\u003cli\u003e14 TPI external UNJ thread form with 60-degree included angle and controlled root radius\u003c\/li\u003e\n\u003cli\u003e3ER insert style for standard laydown external threading toolholders\u003c\/li\u003e\n\u003cli\u003e3\/8 inch inscribed circle sizing for common external turning applications\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting orientation\u003c\/li\u003e\n\u003cli\u003eMeets ISO 9001:2008 and MIL-S-8879C standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 3ER-style laydown external threading toolholders.

Use the correct torque wrench and insert screw specified by the toolholder manufacturer when seating the insert. Inspect the insert pocket for chips or debris before seating a new insert, as contamination will affect thread form accuracy. Thread-form inserts for UNJ applications should be verified against a thread gauge after the first pass to confirm correct root profile.\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\u003eThread Standard\u003c\/strong\u003e: UNJ External\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 14 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch\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\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 Codes\u003c\/strong\u003e: 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: ISO 9001:2008, MIL-S-8879C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291804\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: 51368\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VARGUS","offers":[{"title":"Default Title","offer_id":67909689409842,"sku":"51368","price":314.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/988c5a8f864bd7aa009cd43f4f9f5697.jpg?v=1791189914","url":"https:\/\/voomisupply.com\/products\/vargus-51368-3er14unj-vkx-threading-insert-14-tpi-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
