It carries manufacturer grade 1125 with a PVD-applied TiAlN and TiCrAlN dual-layer coating that supports high cutting speeds and extended tool life. The insert covers a thread range of 8 to 16 TPI (1.50 to 3.00 mm pitch), features a 3\/8 inch (9.53 mm) inscribed circle, and is 5\/32 inch (3.97 mm) thick. It belongs to the CoroThread 266 series and is installed by machinists and CNC tooling technicians in production threading applications on lathes and turning centers.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for external threading on turned components in job shop and production environments. The right-hand cutting geometry and single-tooth profile make it appropriate for generating 60-degree V-form threads on ferrous and non-ferrous workpieces. The A chipbreaker designation is optimized for controlled chip evacuation during threading passes. Applications include threading on steel, stainless, and similar materials where a consistent, repeatable thread form is required across medium-to-high volume runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with PVD TiAlN and TiCrAlN dual-layer coating for heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003eCovers 8-16 TPI (1.50-3.00 mm pitch) external 60-degree V-thread range in a single insert\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting orientation for standard external threading operations\u003c\/li\u003e\n  \u003cli\u003eCoroThread 266 series insert style with A chipbreaker for reliable chip control\u003c\/li\u003e\n  \u003cli\u003e0.20 mm (0.0079 inch) corner radius for precise thread root geometry\u003c\/li\u003e\n  \u003cli\u003eMounting hole diameter of 4.40 mm (0.1732 inch) for positive insert clamping\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement insert for SANDVIK COROMANT CoroThread 266 series toolholders accepting 16-size laydown threading inserts with the 266RG insert style designation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before seating or removing the insert. Use the manufacturer-specified torx or clamping screw driver to secure the insert at the correct clamping torque per the toolholder documentation. Inspect the insert pocket and clamping screw for wear or debris before installing a new insert to ensure proper seating and thread form accuracy.\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\u003eThread Type\u003c\/strong\u003e: 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\u003eInsert Hand\u003c\/strong\u003e: Right Hand\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\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\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Finish\u003c\/strong\u003e: TiAlN and TiCrAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 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: 5757915\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51755020419378,"sku":"5757915","price":571.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cd94e254890a5252541427527eff509e_1e6295f0-90bc-4dbf-8bf8-df23d11b8a18.jpg?v=1788950529","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5757915-threading-insert-8-16-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
