It cuts a 60-degree V thread profile at 12 to 24 threads per inch (TPI), covering a pitch range of 1.00 to 2.00 mm. The insert carries a PVD-applied dual-layer TiAlN and TiCrAlN coating for wear resistance and thermal stability during high-speed threading operations. With a 3\/8-inch (9.53 mm) inscribed circle and a thickness of 5\/32 inch (3.97 mm), it is sized for standard CoroThread 266 holders. Licensed machinists and CNC operators install this insert in turning centers and threading lathes for precision internal thread production.\u003c\/p\u003e\u003cp\u003eThis insert is suited for internal threading on CNC lathes and turning centers in production machining environments, including job shops and manufacturing facilities. It is designed to produce 60-degree V threads in a right-hand direction, making it applicable to standard unified and metric thread forms within the 12 to 24 TPI range. The A chipbreaker geometry supports controlled chip evacuation in internal bores. Typical materials threaded with carbide grade 1125 and PVD coating include steels and other machinable alloys.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate with PVD-applied TiAlN and TiCrAlN dual-layer coating for extended tool life\u003c\/li\u003e\n\u003cli\u003eRight-hand internal 60-degree V thread form, 12 to 24 TPI (1.00 to 2.00 mm pitch)\u003c\/li\u003e\n\u003cli\u003e3\/8-inch (9.53 mm) inscribed circle with 5\/32-inch (3.97 mm) thickness\u003c\/li\u003e\n\u003cli\u003eA chipbreaker geometry for controlled chip formation in internal threading\u003c\/li\u003e\n\u003cli\u003eInsert style 266 for use with CoroThread 266 tooling system\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0024 inch (0.06 mm) for accurate thread root form\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with CoroThread 266 series threading holders accepting insert size code 16 with a 0.1732-inch (4.40 mm) hole diameter.

Use the appropriate Torx or hex key to seat the insert securely in the holder pocket; do not overtighten or use impact tools on the clamping screw. Inspect the insert pocket and clamping components for wear or damage before seating a new insert. Handle carbide inserts with care to avoid edge chipping prior to use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroThread 266\u003c\/li\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\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN and TiCrAlN (PVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Right Hand Internal\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch Range\u003c\/strong\u003e: 1.00 to 2.00 mm\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 (3.97 mm) \/ 0.1563 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0024 inch (0.06 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\u003eChipbreaker\u003c\/strong\u003e: A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\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: 0.13 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: 5757961\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51749794414898,"sku":"5757961","price":612.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cd94e254890a5252541427527eff509e_5bde3aed-fe9b-4d1e-ba75-99a76f811a36.jpg?v=1788910562","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5757961-threading-insert-12-24-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
