It carries the 3JER insert style designation and features a TiAlN coating applied via PVD process, delivering hardness and heat resistance suited for demanding threading operations. The 3\/8-inch inscribed circle (IC) size and 60-degree included angle conform to standard UN thread geometry. The SCB chipbreaker promotes consistent chip evacuation during threading passes. This insert is intended for use by machinists and CNC lathe operators in production or job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThe VARGUS 53574 is used for right-hand external UN threading on CNC lathes and manual turning centers. With a universal primary workpiece material designation, it is rated for use across a broad range of materials including steel, stainless steel, cast iron, non-ferrous alloys, heat-resistant alloys, and aluminum. Its standard series classification makes it a direct-fit replacement for common threading insert holders accepting the 3ER insert style. Typical applications include threading fastener components, fittings, and shaft ends in precision machining environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with TiAlN PVD coating for wear and heat resistance\u003c\/li\u003e\n  \u003cli\u003e3JER insert style with 3\/8-inch inscribed circle for standard UN thread geometry\u003c\/li\u003e\n  \u003cli\u003eRight-hand external thread orientation at 12 TPI and 60-degree included angle\u003c\/li\u003e\n  \u003cli\u003eSCB chipbreaker design for controlled chip evacuation during threading\u003c\/li\u003e\n  \u003cli\u003eUniversal material grade (H, K, M, N, P, S) covering steel, stainless, cast iron, non-ferrous, high-temp alloys, and aluminum\u003c\/li\u003e\n  \u003cli\u003eManufactured under ISO 9001:2008 quality standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a laydown threading insert in the 3ER style for use in standard threading insert toolholders accepting a 3\/8-inch IC insert.

Ensure the machine spindle is fully stopped and all motion is locked out before seating or replacing the insert. Use the appropriate torque wrench and clamping hardware specified by the toolholder manufacturer to secure the insert without over-tightening. Verify thread pitch and insert orientation against the job setup sheet 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\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inches\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\u003eHand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 12 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 Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: VCB\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\u003eChipbreaker\u003c\/strong\u003e: SCB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Standard\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\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\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: 53574\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VARGUS","offers":[{"title":"Default Title","offer_id":67916554830130,"sku":"53574","price":314.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b916e11eaf5c92da039633690a69d530.jpg?v=1791258404","url":"https:\/\/voomisupply.com\/products\/vargus-53574-laydown-threading-insert-3jer12un-vcb-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
