Part of the CoroThread 266 series, it is manufactured from solid carbide and features a dual-layer PVD coating of TiCrAlN and TiAlN for extended tool life in demanding threading applications. The insert is configured for right-hand cutting at 18 threads per inch with a 60-degree included angle, a 3\/8 inch inscribed circle, and a thickness of 5\/32 inch (0.1563 inches). It carries manufacturer grade 1125 and chipbreaker designation A. This insert is installed by machinists and CNC operators working in metal fabrication, job shop, and production turning environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for external UN threading on CNC lathes and turning centers in both production and job shop settings. The CoroThread 266 platform is engineered for consistent thread form and reliable chip control across a range of workpiece materials. Typical applications include threading of fasteners, fittings, and mechanical components requiring standard unified national thread profiles. The single-tooth-per-side geometry and insert size code 16 configuration make it appropriate for moderate-depth threading passes on ferrous and non-ferrous materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with PVD-applied TiCrAlN and TiAlN dual-layer coating for wear resistance\u003c\/li\u003e\n  \u003cli\u003eRight-hand external UN thread profile at 18 TPI with 60-degree included angle\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch inscribed circle and 0.1563 inch thickness for precise seating in CoroThread 266 toolholders\u003c\/li\u003e\n  \u003cli\u003eChipbreaker designation A for controlled chip formation during threading passes\u003c\/li\u003e\n  \u003cli\u003eInsert size code 16 with 0.1732 inch hole diameter for secure clamping\u003c\/li\u003e\n  \u003cli\u003eSingle tooth per side geometry suited for consistent thread form on each pass\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement threading insert for use in CoroThread 266 series toolholders accepting insert size code 16 with a 3\/8 inch inscribed circle and right-hand external UN thread configuration.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or CNC technicians. The machine spindle must be stopped and all motion arrested before indexing or replacing inserts. Use the appropriate torque wrench and clamping hardware specified for the CoroThread 266 toolholder to seat the insert correctly. Do not exceed the recommended depth of cut or feed rate for the grade and coating combination, and inspect the insert seat for chips or contamination before seating a new 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\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: TiCrAlN and TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UN\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: 18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\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: 5\/32 inch (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\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\u003eInsert Size Code\u003c\/strong\u003e: 16\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: 5757942\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51746767929650,"sku":"5757942","price":474.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cd94e254890a5252541427527eff509e_951ee4fb-51cf-49a5-bd9b-ce550e31772a.jpg?v=1788873461","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5757942-threading-insert-18-tpi-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
