Part of the CoroThread 266 series, it features a TiCrAlN\/TiAlN PVD coating for extended tool life in a wide range of workpiece materials. This insert handles right-hand external 60-degree V threads across a pitch range of 4 to 7 TPI (3.50 to 6.00 mm pitch). The 1\/2-inch (12.70 mm) inscribed circle and 5.56 mm thickness conform to the 266 insert standard. Installation is performed by qualified machinists and CNC tooling technicians during lathe tooling setup.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for single-point external threading operations in production and job-shop environments. It covers a broad pitch range, making it practical for threading operations on fastener profiles, hydraulic fittings, and general-purpose threaded components. The A chipbreaker geometry and single tooth per side design are optimized for controlled chip formation during threading passes. The manufacturer catalog number for this insert is 266RG-22VM01A001M 1125.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with PVD-applied TiCrAlN\/TiAlN dual-layer coating for wear and heat resistance\u003c\/li\u003e\n  \u003cli\u003eRight-hand external 60-degree V thread form covering 4 to 7 TPI (3.50 to 6.00 mm pitch)\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch (12.70 mm) inscribed circle, 0.2190-inch (5.56 mm) thickness  -  CoroThread 266 form factor\u003c\/li\u003e\n  \u003cli\u003eA chipbreaker geometry for controlled chip evacuation during threading passes\u003c\/li\u003e\n  \u003cli\u003e0.48 mm (0.0189-inch) corner radius for consistent thread root form\u003c\/li\u003e\n  \u003cli\u003eManufacturer grade 1125  -  PVD-coated carbide grade suited for threading at moderate to high cutting speeds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement insert for CoroThread 266 series toolholders accepting 22-size laydown threading inserts with a 5.70 mm hole diameter and 1\/2-inch inscribed circle.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine before seating or removing inserts. Ensure the insert pocket and clamping screw are free of chips and debris before installation to prevent insert rocking or premature failure. Follow the toolholder manufacturer torque specification for the clamping screw  -  do not over-tighten, as solid carbide inserts are brittle.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 266\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroThread 266\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: 1125\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiCrAlN \/ TiAlN (PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Right Hand External\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: 60-Degree V\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 4-7 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch Range\u003c\/strong\u003e: 3.50 to 6.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 1\/2 inch (12.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.2190 inches (5.56 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0189 inches (0.48 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2244 inches (5.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: A\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\u003eInsert Size Code\u003c\/strong\u003e: 22\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Catalog Number\u003c\/strong\u003e: 266RG-22VM01A001M 1125\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.32 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: SANDVIK COROMANT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5758051\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51742606819634,"sku":"5758051","price":752.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cd94e254890a5252541427527eff509e_0977ac8c-d0c2-4aea-be07-823ebdf1e706.jpg?v=1788838335","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5758051-threading-insert-4-7-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
