It carries a dual PVD coating of TiCrAlN and TiAlN for extended cutting tool life at elevated temperatures. The insert features a right-hand cutting orientation, a 60-degree included angle, and a 1.50 mm pitch, making it suited for standard metric external thread profiles. Licensed HVAC, plumbing, and piping fabrication machinists as well as precision metalworking shops rely on this type of insert when threading stainless, alloy steels, and similar materials on CNC lathes and turning centers.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for use in external metric threading operations on turning machines. Its 266 insert style and 16 size code are compatible with CoroThread 266 toolholders configured for laydown-style inserts. The chipbreaker designation A and a 3\/8-inch (9.53 mm) inscribed circle make it appropriate for medium-range workpiece diameters in both production and job-shop environments. Two teeth per side allow efficient threading passes.\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 coating for wear resistance\u003c\/li\u003e\n  \u003cli\u003eRight-hand, external metric 60-degree thread form at 1.50 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\u003eChipbreaker style A for controlled chip evacuation during threading passes\u003c\/li\u003e\n  \u003cli\u003eTwo teeth per side for efficient multi-tooth threading\u003c\/li\u003e\n  \u003cli\u003eCoroThread 266 series insert style 266, size code 16, manufacturer grade 1125\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CoroThread 266 series toolholders that accept laydown-style threading inserts with insert style 266 and size code 16.

Ensure the CNC lathe or turning center is fully stopped and the spindle is locked before changing inserts. Use the correct torx or hex key torque driver specified by the toolholder manufacturer to seat the insert clamp screw. Inspect the toolholder pocket for chips or debris before seating the insert to avoid micro-fractures in the carbide substrate.\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 Type\u003c\/strong\u003e: External\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric 60 Degree\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: 1.50 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: A\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 decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 4.40 mm (0.1732 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Teeth Per Side\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN and TiCrAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291804\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.14 pounds\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: 5757907\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51733566554418,"sku":"5757907","price":921.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7d1c0e5b4d782b5cb21276cc221b39d6_3efcec6f-bb5c-4ee2-8f57-b5f3f5cc0ed2.jpg?v=1788756419","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5757907-threading-insert-metric-60","provider":"Voomi Supply","version":"1.0","type":"link"}
