Part of the CoroThread 266 series, it is manufactured from solid carbide and carries a PVD-applied TiCrAlN\/TiAlN dual-layer coating that supports wear resistance in demanding threading operations. The insert features a 60-degree included angle, a right-hand cutting orientation, and a single tooth per side. Machinists and CNC lathe operators working on pipe fitting and fluid-system components use this insert for consistent, precision NPTF thread profiles.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for external NPTF threading applications on lathes and turning centers. NPTF threads are a taper pipe thread standard used in fluid and gas system connections where a pressure-tight seal is required without additional sealant. The CoroThread 266 insert style is a laydown configuration, meaning the insert seats flat in a dedicated 266-series toolholder. This geometry is common in production environments where thread quality and repeatability are critical across high-volume runs on ferrous and non-ferrous workpieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate for rigidity and wear resistance in threading operations\u003c\/li\u003e\n  \u003cli\u003ePVD-applied TiCrAlN\/TiAlN coating for extended tool life\u003c\/li\u003e\n  \u003cli\u003eRight-hand external NPTF thread profile at 11.5 TPI\u003c\/li\u003e\n  \u003cli\u003e60-degree included angle with chipbreaker style A\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch (9.53 mm) inscribed circle, 5\/32 inch (3.97 mm) thickness\u003c\/li\u003e\n  \u003cli\u003eDesigned for use with CoroThread 266 series toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with SANDVIK COROMANT CoroThread 266 series toolholders accepting insert style 266 with size code 16.

Before changing inserts, ensure the machine spindle is fully stopped and the machine is placed in a safe, locked-out state per shop safety procedures. Use the appropriate torx or hex key as specified by the toolholder manufacturer when seating the insert clamp screw. Do not exceed the clamping torque range indicated on the toolholder documentation, and inspect the insert pocket and seating surface for debris before securing the insert.\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\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 Standard\u003c\/strong\u003e: NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: External\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 11.5 TPI\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\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)\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\u003eCoating\/Finish\u003c\/strong\u003e: TiCrAlN\/TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\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: 0.13 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: 5757973\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51744572473650,"sku":"5757973","price":567.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cd94e254890a5252541427527eff509e_98fe87d9-2e52-48ec-a64d-d5df8536e81c.jpg?v=1788858417","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5757973-threading-insert-11-5-tpi-nptf","provider":"Voomi Supply","version":"1.0","type":"link"}
