Part of the CoroThread 266 series, it carries a dual PVD coating of TiAlN and TiCrAlN for wear resistance and thermal stability at the cutting edge. The insert is right-hand oriented, features a 60-degree included angle, and is sized with a 3\/8 inch (9.53 mm) inscribed circle and a thickness of 5\/32 inch (3.97 mm). Manufacturer grade 1125 indicates a tough carbide substrate suited to threading operations where edge integrity is critical. Installation is performed by machinists and CNC tooling specialists on lathes and turning centers.\u003c\/p\u003e\u003cp\u003eThis insert is intended for external UNJ thread forms in precision threading applications, including aerospace and high-strength fastener contexts where UNJ thread profiles are specified. The 266RG-16NJ01A200E 1125 catalog designation aligns it to the CoroThread 266 toolholder system. The single-tooth-per-side geometry and A-style chipbreaker support controlled chip evacuation during threading passes on a range of metallic workpiece materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate, manufacturer grade 1125, for high edge toughness in threading operations\u003c\/li\u003e\n\u003cli\u003eDual PVD coating: TiAlN and TiCrAlN for heat and wear resistance\u003c\/li\u003e\n\u003cli\u003eExternal UNJ thread standard, right-hand cutting, 20 TPI\u003c\/li\u003e\n\u003cli\u003e60-degree included angle with A-style chipbreaker for controlled chip flow\u003c\/li\u003e\n\u003cli\u003e3\/8 inch inscribed circle, 5\/32 inch thickness, 0.1732 inch hole diameter\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 insert style 266, size code 16.
