It belongs to the CoroThread 266 series and carries manufacturer grade 1125, a PVD-coated carbide grade suited for threading in a range of workpiece materials. The insert profile follows the UNJ thread standard with a 60-degree included angle and a right-hand cutting orientation. At 0.1563 inches (3.97 mm) thick, it is engineered for indexable toolholders in the CoroThread 266 system. Licensed machinists and CNC operators rely on this insert for precision external thread generation on turning centers and CNC lathes.\u003c\/p\u003e\u003cp\u003eThis insert is intended for external threading applications in precision machining environments, including aerospace, defense, and industrial manufacturing where UNJ thread forms are specified. The UNJ standard features a controlled root radius, making it common in high-stress fastener applications. The CoroThread 266 series is designed for productive, stable threading with reliable chip control. This insert is sold individually but carries a minimum order quantity of 10 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCarbide substrate with PVD coating for wear resistance and edge integrity\u003c\/li\u003e\n\u003cli\u003eUNJ thread standard with 60-degree included angle for precision thread form accuracy\u003c\/li\u003e\n\u003cli\u003eRight-hand external threading orientation\u003c\/li\u003e\n\u003cli\u003eInsert style 266RG16NJ01A080E, grade 1125\u003c\/li\u003e\n\u003cli\u003ePart of the CoroThread 266 indexable threading system\u003c\/li\u003e\n\u003cli\u003eThickness of 0.1563 inches for consistent seating in compatible 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 266RG insert style.
