Part of the CoroThread 266 series, it is manufactured from solid carbide with a PVD-applied TiAlN and TiCrAlN dual coating for improved wear resistance and tool life at elevated cutting temperatures. The insert cuts right-hand external 60-degree V threads across a range of 12 to 24 threads per inch (TPI), with a corresponding metric pitch range of 1.00 to 2.00 mm. With an inscribed circle of 3\/8 inches and a thickness of 5\/32 inches, this insert is sized for standard CoroThread 266 holders. Machinists and CNC operators working in job shop, production, and contract manufacturing environments are the primary users.\u003c\/p\u003e\u003cp\u003eThis insert is suited for external threading operations on ferrous and non-ferrous materials where a unified 60-degree V thread form is required. It covers the commonly used 12-24 TPI range, making it applicable to general-purpose fastener threads and precision mechanical components. The A-style chipbreaker geometry supports efficient chip evacuation in threading cycles. The PVD coating process preserves sharp cutting edges, which is critical for thread form accuracy. This insert is sold individually with a minimum order quantity of 10 units per order.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate with PVD TiAlN and TiCrAlN dual-layer coating for extended tool life\u003c\/li\u003e\n\u003cli\u003eRight-hand external 60-degree V thread form, 12-24 TPI (1.00-2.00 mm pitch)\u003c\/li\u003e\n\u003cli\u003eCoroThread 266 series geometry with A-style chipbreaker for controlled chip flow\u003c\/li\u003e\n\u003cli\u003e3\/8 inch (9.53 mm) inscribed circle and 5\/32 inch (3.97 mm) thickness for CoroThread 266 holders\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0051 inches (0.13 mm) for precise thread root form\u003c\/li\u003e\n\u003cli\u003eHole diameter of 0.1732 inches (4.40 mm) for secure clamping in compatible toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with SANDVIK COROMANT CoroThread 266 series threading toolholders that accept the 266 insert style with a 16 size code.

Power down and lock out the machine spindle before changing or seating inserts. Use the manufacturer-specified torque tool and clamping screw to secure the insert  -  do not overtighten by hand. Inspect the insert seat and clamping pocket for chips or debris before seating a new insert to ensure proper contact and thread form accuracy.\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\u003eInsert Size Code\u003c\/strong\u003e: 16\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\u003eSeries\u003c\/strong\u003e: CoroThread 266\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: 12-24 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: 1.00-2.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inches (9.53 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 5\/32 inches (3.97 mm \/ 0.1563 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0051 inches (0.13 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\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\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\u003eNumber of Teeth Per Side\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.14 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: 5757913\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51743357894962,"sku":"5757913","price":567.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cd94e254890a5252541427527eff509e_8bfae777-7bd5-4ebd-bba8-c7f75753b3a7.jpg?v=1788846121","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5757913-threading-insert-12-24-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
