It carries a dual PVD coating of TiAlN and TiCrAlN for extended wear resistance and thermal stability at the cutting edge. The insert produces Metric 60-degree threads at a 1.50 mm pitch and features an inscribed circle of 0.375 inches (9.53 mm) with a thickness of 0.1563 inches (3.97 mm). Manufacturer grade 1125 indicates a tough carbide substrate suited to a range of ferrous and non-ferrous workpiece materials. Licensed machinists and CNC lathe operators install this insert in compatible CoroThread 266 toolholders on CNC turning centers.\u003c\/p\u003e\u003cp\u003eThis insert is suited for internal threading on CNC turning centers in both production and job-shop environments. Its right-hand orientation and Metric 60-degree thread standard make it a standard choice for metric fastener thread forms in precision machining applications. The chipbreaker designation A and single tooth-per-side configuration support consistent chip control in through-bore and blind-bore threading cycles. It is appropriate for light-to-medium threading passes on steel, stainless, and similar materials where a PVD-coated carbide grade is specified.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate with dual PVD coating: TiAlN and TiCrAlN for heat and wear resistance\u003c\/li\u003e\n\u003cli\u003eRight-hand internal Metric 60-degree thread form at 1.50 mm pitch\u003c\/li\u003e\n\u003cli\u003eInscribed circle of 0.375 inches (9.53 mm); thickness of 0.1563 inches (3.97 mm)\u003c\/li\u003e\n\u003cli\u003eManufacturer grade 1125 for balanced toughness and wear performance\u003c\/li\u003e\n\u003cli\u003eChipbreaker style A for controlled chip evacuation in internal threading\u003c\/li\u003e\n\u003cli\u003ePart of the CoroThread 266 series for use with compatible 266-series toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with SANDVIK COROMANT CoroThread 266 series toolholders that accept the 16 insert size code.

Use the correct torx or hex key specified for the CoroThread 266 clamping screw to seat the insert securely without over-torquing the clamp. Inspect the insert seat and clamping components for chips or debris before seating the new insert. Verify thread pitch and hand orientation against the workpiece drawing before initiating the threading cycle.\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\u003eThread Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric 60 degrees\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\u003ePitch\u003c\/strong\u003e: 1.50 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.375 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\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\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN and TiCrAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\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: 5757984\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51737303253298,"sku":"5757984","price":510.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cd94e254890a5252541427527eff509e_2d0ddd41-c3a8-4af7-9753-0a8f5d5279b4.jpg?v=1788786842","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5757984-threading-insert-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
