Part of the CoroThread 266 series, it carries a dual PVD coating of TiAlN and TiCrAlN for heat resistance and extended tool life in demanding threading operations. The insert covers a thread range of 8 to 16 TPI, equivalent to a metric pitch range of 1.50 to 3.00 mm, making it suitable for a wide range of fastener and component thread profiles. It is installed by machinists and CNC operators on compatible CoroThread 266 toolholders and is suited for production threading on lathes and turning centers.\u003c\/p\u003e\u003cp\u003eThis insert is used in external threading operations where a left hand thread orientation is required. It fits applications across general machining, aerospace component manufacturing, and precision parts production. The CoroThread 266 series is built for rigid setups on CNC lathes and turning centers where consistent thread form and surface finish are critical. The 60-degree included angle covers the most common unified and metric V-thread standards, and the single-tooth design allows focused cutting force control during the threading pass.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate with PVD-applied TiAlN and TiCrAlN dual coating for wear and heat resistance\u003c\/li\u003e\n\u003cli\u003eLeft hand external thread cutting geometry for left hand thread applications\u003c\/li\u003e\n\u003cli\u003eCovers 8 to 16 TPI and 1.50 to 3.00 mm pitch range in a single insert\u003c\/li\u003e\n\u003cli\u003e60-degree included angle compatible with standard unified and metric V-thread profiles\u003c\/li\u003e\n\u003cli\u003e3\/8 inch (9.53 mm) inscribed circle with A chipbreaker designation\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0079 inches (0.20 mm) for precise thread root form\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 insert size code 16 laydown threading inserts.

Seat the insert firmly into the toolholder pocket and tighten the clamping screw to the toolholder manufacturer's specified torque using a calibrated torque driver. Inspect the insert seat and pocket for chips or debris before installation, as contamination can affect insert seating and thread accuracy. Never attempt to re-grind or modify a coated carbide threading insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 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: Left Hand External\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: 8-16 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch Range\u003c\/strong\u003e: 1.50 to 3.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\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: 5\/32 inches (3.97 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0079 inches (0.20 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\u003ePackage Dimensions\u003c\/strong\u003e: 3.74 x 1.54 x 0.43 inches\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\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: 5757702\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51749761909042,"sku":"5757702","price":616.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cd94e254890a5252541427527eff509e_3ac7a73e-0759-4501-b756-2b5a83ae1b3d.jpg?v=1788910139","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5757702-laydown-threading-insert-8-16-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
