It carries the VTX manufacturer grade with a TiAlN coating applied via PVD process, delivering hard, wear-resistant performance across a wide range of workpiece materials. The insert features a 60-degree included angle and an inscribed circle of 12.70 mm (1\/2 inch), with a thickness of 4.76 mm. It fits the 4IR insert style and is built to ANSI B1.1:74 thread standards. Machinists and toolroom technicians use this insert for precise internal threading operations on CNC lathes and turning centers.\u003c\/p\u003e\u003cp\u003eThis insert is suited for internal UN threading applications in production and job-shop environments. The Universal primary workpiece material designation means it performs across multiple material groups, including ISO categories H, K, M, N, P, and S. That range covers hardened steels, cast irons, stainless steels, non-ferrous metals, carbon and alloy steels, and high-temperature superalloys. The 4IR style fits standard laydown threading toolholders of matching insert seat geometry, making it a straightforward drop-in for existing setups running UN internal thread profiles.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with TiAlN PVD coating for extended tool life\u003c\/li\u003e\n\u003cli\u003eVTX grade optimized for broad material compatibility across ISO groups H, K, M, N, P, and S\u003c\/li\u003e\n\u003cli\u003eRight-hand internal UN thread profile at 7 TPI with 60-degree included angle\u003c\/li\u003e\n\u003cli\u003eInscribed circle of 12.70 mm (1\/2 inch) in the standard 4IR insert style\u003c\/li\u003e\n\u003cli\u003eMeets ANSI B1.1:74 thread standards; manufactured under ISO 9001:2008 quality system\u003c\/li\u003e\n\u003cli\u003eSingle tooth per side geometry for controlled chip formation in threading cuts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in 4IR-style laydown threading toolholders configured for right-hand internal UN thread cutting at 7 TPI.

Seat the insert firmly against all locating surfaces of the toolholder pocket before tightening the clamp or screw to the toolholder manufacturer's specified torque. Inspect the insert seat and clamping components for chips or wear before seating a new insert. Verify thread profile and TPI setup with a thread gauge on the first part before running production.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 4IR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 4\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: VTX\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\u003eThread Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 7\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: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 12.70 mm (1\/2 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 4.76 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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Universal (ISO groups H, K, M, N, P, S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI B1.1:74; ISO 9001:2008\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: 59483\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VARGUS","offers":[{"title":"Default Title","offer_id":67906376991026,"sku":"59483","price":441.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b0be16de9b93021a88a59cddd141b247_ab6e19c6-3b13-4f24-bd8a-bfecd9079686.jpg?v=1791167674","url":"https:\/\/voomisupply.com\/products\/vargus-59483-laydown-threading-insert-4ir-7-tpi-un","provider":"Voomi Supply","version":"1.0","type":"link"}
