Carrying the VKX grade designation, it features a PVD-applied TiN coating for wear resistance and extended tool life in production threading applications. The insert is configured for right-hand internal threading at 12 threads per inch with a 60-degree included angle, making it suitable for standard unified inch thread forms. Machinists and tooling specialists install this insert into compatible laydown-style threading toolholders as part of routine insert indexing or replacement.\u003c\/p\u003e\u003cp\u003eThis insert is intended for internal UN thread applications in ferrous and non-ferrous materials where a 3JIR insert style is specified. With a 3\/8-inch (9.53 mm) inscribed circle and 3.60 mm thickness, it fits the standard laydown insert pocket geometry. It is well suited for job shops, production machining environments, and CNC threading operations requiring consistent thread form accuracy at 12 TPI.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with PVD TiN coating for heat and wear resistance\u003c\/li\u003e\n\u003cli\u003eRight-hand internal UN thread form at 12 TPI with 60-degree included angle\u003c\/li\u003e\n\u003cli\u003eInsert style 3JIR fits standard laydown threading toolholders\u003c\/li\u003e\n\u003cli\u003e3\/8-inch (9.53 mm) inscribed circle for precise pocket seating\u003c\/li\u003e\n\u003cli\u003eVKX manufacturer grade optimized for threading performance\u003c\/li\u003e\n\u003cli\u003eSingle tooth per side geometry for controlled thread engagement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement insert for laydown threading toolholders accepting the 3JIR insert style with a 3\/8-inch inscribed circle and 3.60 mm thickness.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician. Always power down and lock out the machine spindle before indexing or replacing threading inserts. Use the correct torque wrench and insert screw specified by the toolholder manufacturer to seat the insert properly without cracking the carbide. Inspect the insert pocket and clamping screw for wear or debris before installing a new insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 3JIR\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\u003eThread Standard\u003c\/strong\u003e: UN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\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: 12\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 inch (9.53 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3.60 mm\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\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\u003eWeight\u003c\/strong\u003e: 0.01 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: 52146\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VARGUS","offers":[{"title":"Default Title","offer_id":67910123651378,"sku":"52146","price":314.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ee5ec204b830350e40253add319f8edc_8f04fee3-5f39-41da-bd48-53dd2ea6b0af.jpg?v=1791196082","url":"https:\/\/voomisupply.com\/products\/vargus-52146-threading-insert-12-tpi-un-internal-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
