It carries a TiCrAlN\/TiN PVD coating for wear resistance and thermal stability during high-speed threading operations. Part of the CoroThread 266 series, this right-hand insert features a 60-degree included angle, a 3\/8 inch inscribed circle, and a 5\/32 inch thickness. It is installed by machinists and tooling specialists on CNC lathes and threading tool holders configured for the 266 insert style. The A chipbreaker geometry supports controlled chip evacuation in single-point external threading applications.\u003c\/p\u003e\n\u003cp\u003eThis insert is used in precision threading applications where UN-standard external threads are required. The CoroThread 266 platform is common in production turning environments handling medium to high-volume threading cycles on ferrous and non-ferrous workpieces. The 16 TPI specification targets thread sizes common in general mechanical fastener and connector production. The insert is sold individually with a minimum order quantity of 10 units, making it suited for shop stock replenishment or tooling room inventory.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with TiCrAlN\/TiN PVD coating for extended tool life\u003c\/li\u003e\n  \u003cli\u003eRight-hand external UN thread geometry at 16 threads per inch\u003c\/li\u003e\n  \u003cli\u003e60-degree included angle for standard UN thread form accuracy\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch inscribed circle, compatible with 266-series tool holders\u003c\/li\u003e\n  \u003cli\u003eA chipbreaker for reliable chip control in single-point threading\u003c\/li\u003e\n  \u003cli\u003eManufacturer grade 1135 optimized for the CoroThread 266 system\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with SANDVIK COROMANT CoroThread 266 series threading tool holders accepting insert style 266 with a 16-size insert code.
