Manufactured from solid carbide with a PVD-applied TiAlN coating, this insert delivers consistent thread form geometry in a right-hand cutting orientation. The 2IR insert style seats in standard laydown toolholders and features a 60-degree included angle conforming to UN thread profile requirements. With an inscribed circle of 0.25 inches and a thickness of 0.125 inches, it fits compact boring bar setups commonly used in CNC turning and manual lathe applications. Licensed machinists and toolroom operators are the primary installers of this insert type.\u003c\/p\u003e\u003cp\u003eThis insert is suited for internal threading operations on a wide range of workpiece materials. The TiAlN coating and VTX grade designation make it compatible with universal material groups, including ferrous alloys, stainless steels, titanium alloys, aluminum, and non-ferrous metals corresponding to material codes H, K, M, N, P, and S. It is well-suited for production threading in CNC turning centers and manual lathes where a 28 TPI UN internal thread profile is required. The single-tooth-per-side geometry provides clean thread form engagement on each pass.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate with PVD TiAlN coating for wear resistance across universal workpiece materials\u003c\/li\u003e\n\u003cli\u003e28 TPI cutting profile with 60-degree included angle for UN thread standard conformance per ANSI B1.1:74\u003c\/li\u003e\n\u003cli\u003e2IR laydown insert style fits standard internal threading toolholders\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting orientation for conventional internal threading operations\u003c\/li\u003e\n\u003cli\u003eInscribed circle of 0.25 inches supports compact boring bar and small-bore tooling setups\u003c\/li\u003e\n\u003cli\u003eManufactured under ISO 9001:2008 quality standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement laydown threading insert for standard 2IR internal threading toolholders used in CNC turning and manual lathe applications requiring a 28 TPI UN thread profile.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis insert is installed by machinists or toolroom technicians into compatible 2IR laydown toolholders. Power down and lock out the machine spindle before changing inserts. Use the correct insert clamp screw and torque driver specified by the toolholder manufacturer to secure the insert seat. Inspect the toolholder pocket for chips or wear before seating a new insert to ensure accurate thread form reproduction.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 2IR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UN (ANSI B1.1:74)\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: 28\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: 0.25 inches (6.35 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.125 inches (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: 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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Universal (H, K, M, N, P, S)\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\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: 52961\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VARGUS","offers":[{"title":"Default Title","offer_id":67910197510450,"sku":"52961","price":314.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b0be16de9b93021a88a59cddd141b247_080d7200-ed51-4c1d-85a2-bf35113c55fc.jpg?v=1791196616","url":"https:\/\/voomisupply.com\/products\/vargus-52961-threading-insert-2ir-28-tpi-internal-un-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
