Part of the CoroThread 266 series, it carries a PVD-applied TiCrAlN\/TiN coating that resists heat and wear across demanding threading operations. The insert is designed for right-hand cutting at 10 threads per inch, with a 3\/8 inch (9.53 mm) inscribed circle and a thickness of 5\/32 inch (3.97 mm). The 60-degree included angle, F chipbreaker, and single-tooth-per-side geometry make this insert well suited for controlled chip formation during external thread profiling on CNC lathes and turning centers.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for use in metalworking applications where Stub Acme external threads must be machined to consistent form and finish. Typical environments include production turning operations in job shops and manufacturing facilities. The CoroThread 266 series is designed for use with compatible Sandvik Coromant CoroThread 266 toolholders. Machinists working with threaded lead screws, power transmission components, and linear actuation hardware are the primary users of this insert geometry. The 1135 grade and PVD coating combination targets a broad range of workpiece materials commonly encountered in general machining.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with PVD-applied TiCrAlN\/TiN coating for extended tool life\u003c\/li\u003e\n  \u003cli\u003eRight-hand external Stub Acme thread profile at 10 TPI\u003c\/li\u003e\n  \u003cli\u003e60-degree included angle with F chipbreaker for controlled chip formation\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch inscribed circle and 5\/32 inch thickness — CoroThread 266 series geometry\u003c\/li\u003e\n  \u003cli\u003eSingle tooth per side for precise thread form accuracy\u003c\/li\u003e\n  \u003cli\u003eManufacturer grade 1135 suitable for a broad range of workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with compatible SANDVIK COROMANT CoroThread 266 series toolholders accepting 16-size laydown threading inserts with Stub Acme external thread geometry.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. The machine spindle must be stopped and all stored energy released before indexing or replacing threading inserts. Use the appropriate torx or clamping key specified for CoroThread 266 toolholder seats to secure the insert without over-torquing the clamping screw. Verify thread form with a gauge after first-pass cuts before proceeding to full production runs.\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: 1135\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiCrAlN\/TiN\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: Stub Acme\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: 10 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: F\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 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\u003eHole Diameter\u003c\/strong\u003e: 0.1732 inch (4.40 mm)\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\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: 5857563\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51733134967090,"sku":"5857563","price":763.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ccf231290dee11ab915e377269a06c67_37db9f90-85f9-4a2c-88fd-3dbe83f30f72.jpg?v=1788751715","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5857563-threading-insert-10-tpi-stub-acme","provider":"Voomi Supply","version":"1.0","type":"link"}
