This insert is part of the CoroThread 266 series and carries manufacturer grade 1135 with a PVD-applied TiCrAlN\/TiN finish for wear resistance and extended tool life. It cuts right-hand external 60-degree V threads across a range of 8-16 TPI (1.50-3.00 mm pitch), making it suitable for a broad range of common fastener and fitting thread profiles. The insert measures 3\/8 inch (9.53 mm) inscribed circle and 5\/32 inch (0.1563 inch decimal) thick, with a corner radius of 0.0079 inch (0.20 mm).\u003c\/p\u003e\n\u003cp\u003eThis threading insert is used in metal cutting and machining applications where external V-thread profiles are required on turned components. It is appropriate for production environments machining steel, alloy steel, and similar materials where a PVD-coated carbide grade provides consistent thread form and surface finish. The F chipbreaker geometry is suited for controlled chip evacuation during threading passes. CNC machinists, toolroom technicians, and precision machining shops are the primary users of this insert type.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with PVD TiCrAlN\/TiN coating for hardness and heat resistance\u003c\/li\u003e\n  \u003cli\u003eCuts right-hand external 60-degree V threads from 8 to 16 TPI (1.50-3.00 mm pitch)\u003c\/li\u003e\n  \u003cli\u003eCoroThread 266 series with manufacturer grade 1135 for repeatable threading performance\u003c\/li\u003e\n  \u003cli\u003eF chipbreaker geometry for controlled chip flow during external threading passes\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.0079 inch (0.20 mm) for accurate thread root form\u003c\/li\u003e\n  \u003cli\u003eInscribed circle of 3\/8 inch (9.53 mm) for use in compatible 266-series toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in SANDVIK COROMANT CoroThread 266 series toolholders that accept the 16-size laydown insert with a 0.1732 inch (4.40 mm) hole diameter.

Use the appropriate torx or clamping screw driver specified for the CoroThread 266 toolholder to secure the insert without over-torquing the clamping screw. Inspect the insert seat for debris or damage before seating the new insert to ensure proper contact and thread form accuracy. Follow the toolholder manufacturer's setup guidelines and applicable shop safety procedures during all insert changes.\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: 1135\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiCrAlN\/TiN\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: 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: 8-16 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: 1.50-3.00 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: F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (9.53 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1563 inch (3.97 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0079 inch (0.20 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1732 inch (4.40 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\u003eInsert Size Code\u003c\/strong\u003e: 16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturers Catalog Number\u003c\/strong\u003e: 266RG-16VM01F002E 1135\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291804\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.74 inches L x 1.54 inches W x 0.43 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 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: SANDVIK COROMANT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5857587\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51753542025522,"sku":"5857587","price":631.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5929439e42fa52d950984d662a610ba4_8942a652-6f6a-4fe7-acba-e996ea158617.jpg?v=1788938000","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5857587-threading-insert-8-16-tpi-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
