The insert uses the 2IR style geometry with a 60-degree included angle, making it suited for generating tapered pipe thread profiles on a CNC or manual lathe. A TiN (titanium nitride) PVD coating improves wear resistance and tool life across a broad range of workpiece materials. With an inscribed circle of 6.35 mm (1\/4 inch) and a thickness of 3.17 mm, this insert seats in compatible 2IR-style toolholders without shimming. Machinists and tool-room operators who need consistent, on-spec internal pipe threads rely on this insert for production and job-shop applications alike.\u003c\/p\u003e\n\u003cp\u003eThis insert is applied in internal threading operations where NPT tapered pipe thread profiles are required. It is rated for universal workpiece material compatibility, covering common material groups including steels, stainless steels, cast irons, non-ferrous alloys, high-temperature alloys, and titanium. Typical install scenarios include threading bores in hydraulic fittings, pipe couplings, valve bodies, and manifold blocks. Both production shops and MRO machining environments use this insert where repeatable pipe-thread quality is critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with TiN PVD coating for extended wear life\u003c\/li\u003e\n  \u003cli\u003e2IR insert style with 60-degree included angle for NPT thread form accuracy\u003c\/li\u003e\n  \u003cli\u003e18 TPI right-hand internal thread cutting geometry\u003c\/li\u003e\n  \u003cli\u003e6.35 mm (1\/4 inch) inscribed circle  -  fits standard 2IR toolholders\u003c\/li\u003e\n  \u003cli\u003eUniversal material compatibility: steels, stainless, cast iron, non-ferrous, superalloys, titanium\u003c\/li\u003e\n  \u003cli\u003eManufactured to ISO 9001:2008 and USAS B2.1:1968 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in 2IR-style internal threading toolholders.

Seat the insert fully into the toolholder pocket and torque the clamping screw to the toolholder manufacturer's specification before cutting. Power down and lock out the machine spindle before changing inserts. Do not exceed the cutting parameters published by VARGUS for this grade and coating  -  running outside recommended feeds and speeds will reduce tool life and compromise thread accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 2IR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Hand\u003c\/strong\u003e: Right Hand\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: 18 TPI\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: 6.35 mm (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3.17 mm\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\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\u003eStandards\u003c\/strong\u003e: ISO 9001:2008, USAS B2.1:1968\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\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: 50420\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VARGUS","offers":[{"title":"Default Title","offer_id":67907143139634,"sku":"50420","price":314.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ee5ec204b830350e40253add319f8edc_d6b47337-c1b4-4c4c-9787-9c316a4d5616.jpg?v=1791174860","url":"https:\/\/voomisupply.com\/products\/vargus-50420-laydown-threading-insert-18-tpi-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
