Part of the CoroThread 266 series, this insert carries a TiCrAlN\/TiN PVD coating that improves wear resistance and tool life on threading passes. It produces a right-hand external thread at 14 threads per inch with a 60-degree included angle and a single tooth per side cutting profile. The 3\/8-inch inscribed circle and 5\/32-inch thickness place it in the 266-series 16 insert size. Licensed machinists and CNC lathe operators install this insert in compatible CoroThread 266 toolholders for production and job-shop threading work.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for external UN thread generation on CNC lathes and turning centers in both production and repair environments. The F chipbreaker geometry supports controlled chip flow during threading passes. Manufacturer grade 1135 with TiCrAlN\/TiN PVD coating targets steel and similar materials where coating durability under threading loads is a priority. It is appropriate for shop environments requiring precise, repeatable UN thread forms on external diameters.\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 wear resistance\u003c\/li\u003e\n  \u003cli\u003e14 TPI right-hand external UN thread form with 60-degree included angle\u003c\/li\u003e\n  \u003cli\u003eCoroThread 266 series, insert size code 16, manufacturer grade 1135\u003c\/li\u003e\n  \u003cli\u003eF chipbreaker geometry for controlled chip evacuation during threading passes\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch inscribed circle, 5\/32-inch thickness, single tooth per side\u003c\/li\u003e\n  \u003cli\u003eHole diameter of 0.1732 inches for secure toolholder seating\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CoroThread 266 series toolholders accepting a size 16 insert with a 266RG insert style.
