It features a 3IR insert style with an 11.5 threads-per-inch pitch and a 3\/8-inch inscribed circle, making it suited for standard pipe thread profiles. The insert is manufactured from solid carbide and carries a TiN coating applied via a PVD process, which helps maintain cutting edge hardness and resist wear during threading operations. The 30-degree included angle matches the NPT thread form geometry. This insert is intended for use by machinists and toolroom professionals working with CNC lathes or manual threading setups.\u003c\/p\u003e\u003cp\u003eThe VARGUS 52359 is used for right-hand internal NPT threading across a broad range of materials, including ferrous metals, stainless steels, aluminum, exotic alloys, and non-metallic workpieces, as reflected by the universal primary workpiece material designation covering material codes H, K, M, N, P, and S. Typical applications include pipe fitting manufacture, hydraulic component threading, and fluid system component production in both production shop and job shop environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and long tool life in threading applications\u003c\/li\u003e\n\u003cli\u003eTiN coating via PVD process for enhanced wear resistance and surface hardness\u003c\/li\u003e\n\u003cli\u003e3IR insert style with 3\/8-inch inscribed circle for standard laydown toolholder compatibility\u003c\/li\u003e\n\u003cli\u003e11.5 TPI pitch matches NPT thread standard per USAS B2.1:1968\u003c\/li\u003e\n\u003cli\u003eRight-hand cut for standard internal NPT thread direction\u003c\/li\u003e\n\u003cli\u003eUniversal material compatibility across steel, stainless, aluminum, cast iron, and high-temp alloys\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in laydown threading toolholders accepting the 3IR insert style with a 3\/8-inch inscribed circle.

Ensure the toolholder and insert seat are clean and free of chips or debris before seating the insert to prevent improper clamping and edge damage. Verify correct insert orientation for right-hand internal thread cutting before initiating a cut. Follow all machine guarding and lockout procedures per facility safety standards when changing inserts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 3IR\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: NPT\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\u003c\/strong\u003e: 11.5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 30 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: 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\u003c\/strong\u003e: Universal (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\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO 9001:2008, USAS B2.1:1968\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: 52359\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VARGUS","offers":[{"title":"Default Title","offer_id":67914863870258,"sku":"52359","price":314.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ee5ec204b830350e40253add319f8edc_d6c48a7f-fd1b-43fb-b839-929029b7ca5f.jpg?v=1791251364","url":"https:\/\/voomisupply.com\/products\/vargus-52359-threading-insert-3ir-npt-11-5-tpi-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
