Built from solid carbide with a dual-layer PVD coating of TiAlN and TiCrAlN, this insert delivers wear resistance and thermal stability in demanding threading applications. It carries a 60-degree included angle for standard metric thread profiles and a 2.50 mm pitch. With a right-hand cutting orientation and inscribed circle of 0.375 inches (9.53 mm), it fits standard CoroThread 266 series toolholders. Machinists and CNC operators working in production threading environments will find this insert suited to consistent, repeatable internal thread forming.\u003c\/p\u003e\u003cp\u003eThis insert is intended for internal right-hand metric threading in ferrous and non-ferrous materials across manufacturing and machining environments. It belongs to the CoroThread 266 series, which is designed for laydown-style insert seating in dedicated threading toolholders. The chipbreaker style is A, and the single-tooth-per-side geometry is optimized for precise thread profile engagement. Typical applications include threading bores in component parts for industrial, automotive, and general mechanical assembly where metric 60-degree threads are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate for rigidity and long cutting life\u003c\/li\u003e\n\u003cli\u003ePVD-applied TiAlN and TiCrAlN dual-layer coating for thermal and wear resistance\u003c\/li\u003e\n\u003cli\u003eRight-hand internal cutting orientation with 60-degree metric thread profile\u003c\/li\u003e\n\u003cli\u003e2.50 mm pitch for standard metric threading\u003c\/li\u003e\n\u003cli\u003eCoroThread 266 series laydown-style seating geometry\u003c\/li\u003e\n\u003cli\u003eChipbreaker style A for controlled chip formation in internal threading\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CoroThread 266 series threading toolholders that accept size 16 laydown inserts with a 4.40 mm mounting hole diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and indexing should be performed by a qualified CNC machinist or toolroom technician with the spindle fully stopped and the machine in a locked-out state. Use the correct torque wrench and insert clamp screw specified for the CoroThread 266 toolholder to ensure proper seating. Inspect the insert pocket for chips or debris before seating the insert, as contamination can affect thread profile accuracy. Follow the toolholder manufacturer's setup documentation for correct insert orientation and clamping procedure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: TiAlN and TiCrAlN\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: Metric 60 Degree\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: 2.50 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.375 inches (9.53 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1563 inches (3.97 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1732 inches (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\u003eChipbreaker\u003c\/strong\u003e: A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 16\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 5757993\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":67657831186738,"sku":"5757993","price":612.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cd94e254890a5252541427527eff509e_d07075dd-6a1d-41c7-aeea-f8d3c203245c.jpg?v=1790466770","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5757993-threading-insert-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
