Carrying manufacturer grade 1125 and a dual-layer PVD coating of TiCrAlN and TiAlN, this insert delivers wear resistance and heat management suited to precision threading operations. It cuts right-hand external threads at 16 threads per inch with a 60-degree included angle and a single tooth per side geometry. The 3\/8-inch inscribed circle and 5\/32-inch thickness conform to standard insert size code 16 dimensions, making it a direct fit for compatible CoroThread 266 toolholders. Licensed machinists and CNC turning specialists typically install this insert in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for external UNJ thread profiles, a thread standard commonly specified in aerospace and high-integrity fastener applications where root radius control is critical. The 16 TPI pitch suits medium-to-coarse thread applications on ferrous and non-ferrous workpieces. The A chipbreaker geometry supports controlled chip evacuation during threading passes. It is sold individually but carries a minimum order quantity of 10 units, which is standard for indexable carbide inserts at this size and grade.\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 extended tool life\u003c\/li\u003e\n  \u003cli\u003e16 TPI right-hand external UNJ thread form with 60-degree included angle\u003c\/li\u003e\n  \u003cli\u003eInsert size code 16 with 3\/8-inch inscribed circle and 5\/32-inch thickness\u003c\/li\u003e\n  \u003cli\u003eA chipbreaker geometry for controlled chip flow during threading cycles\u003c\/li\u003e\n  \u003cli\u003ePart of the CoroThread 266 series, compatible with 266-series toolholders\u003c\/li\u003e\n  \u003cli\u003eManufacturer grade 1125 suited to precision threading in demanding materials\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, size code 16.

Use the correct torx or clamping key specified for the CoroThread 266 toolholder to achieve proper seating torque without cracking the carbide substrate. Inspect the insert pocket and clamping screw for debris or wear before each insert change. Handle solid carbide inserts carefully to avoid chipping cutting edges prior to use.\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: UNJ\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\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\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inches (9.53 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 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\u003eNumber of Teeth Per Side\u003c\/strong\u003e: 1\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: TiCrAlN \/ TiAlN\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: 5757995\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51728469033266,"sku":"5757995","price":474.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cd94e254890a5252541427527eff509e_964cf161-54f1-41a3-8830-873d81d57242.jpg?v=1788691694","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5757995-threading-insert-16-tpi-unj","provider":"Voomi Supply","version":"1.0","type":"link"}
