Configured in the 3IR insert style, it cuts right-hand internal threads to the UN standard at 20 threads per inch (TPI) with a 60-degree included angle. The bright, uncoated finish suits applications where coating interference with thread tolerances is a concern. With a 3\/8-inch inscribed circle and a thickness of 0.0290 inches, this insert fits standard 3IR toolholders. Machinists and CNC operators working in precision threading applications install this insert for consistent, repeatable internal thread form.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for internal threading operations on ferrous and non-ferrous workpiece materials where an uncoated solid carbide grade provides adequate tool life. The 3IR style is commonly used in production and job-shop environments running UN-specification threads in through-holes and blind holes on CNC turning equipment. Three teeth per side provide multiple usable cutting edges, extending the usable life of each insert before replacement.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3IR insert style fits standard 3IR internal threading toolholders\u003c\/li\u003e\n  \u003cli\u003eCuts UN-standard internal threads at 20 TPI with a 60-degree included angle\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction in VK2P grade, uncoated bright finish\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting orientation for standard internal threading direction\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch inscribed circle, 0.0290-inch thickness for precise toolholder fit\u003c\/li\u003e\n  \u003cli\u003e3 teeth per side for multiple usable cutting edges per insert\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement threading insert for standard 3IR internal threading toolholders used in CNC turning applications requiring UN-thread form at 20 TPI.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before seating or indexing the insert. Ensure the toolholder pocket and clamping screw are clean and free of chips before installing the insert to maintain proper seating and thread-form accuracy. Do not force the insert into the pocket; confirm the insert style and inscribed circle size match the toolholder specification before installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 3IR\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\u003eThreads Per Inch (TPI)\u003c\/strong\u003e: 20\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\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: VK2P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: Bright \/ Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0290 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Teeth Per Side\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 54182\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VARGUS","offers":[{"title":"Default Title","offer_id":67916607062322,"sku":"54182","price":322.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/24b8f9624c83a4f440e1129f7e5759c2_d20a7477-07c7-4b71-a1b1-8980575d4d35.jpg?v=1791258609","url":"https:\/\/voomisupply.com\/products\/vargus-54182-laydown-threading-insert-3ir-20-tpi-un","provider":"Voomi Supply","version":"1.0","type":"link"}
