Part of the CoroThread 266 series, this insert features a left-hand orientation and cuts partial profile 55-degree threads at a 60-degree included angle. It is rated at a manufacturer grade of 1125 with a PVD coating process, delivering wear resistance suited to demanding threading cycles. With an ISO code of 266LL16VW01A002M1125 and a chipbreaker designation of A, this insert provides repeatable thread form geometry in production and job shop environments. Licensed machinists and CNC turning specialists are the primary installers.\u003c\/p\u003e\u003cp\u003eThis insert is used for internal threading applications covering a pitch range of 8 to 14 TPI. It fits standard CoroThread 266 toolholders designed for size 16 inserts. Typical applications include threading bores in ferrous and non-ferrous workpieces on CNC lathes and turning centers. The left-hand configuration is specified for left-hand thread forms or reverse-spindle setups. It suits both production environments with high cycle counts and maintenance shops performing precision thread repairs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate with PVD coating for extended tool life\u003c\/li\u003e\n\u003cli\u003eLeft-hand insert orientation for left-hand internal threading\u003c\/li\u003e\n\u003cli\u003ePartial profile 55-degree thread standard with 60-degree included angle\u003c\/li\u003e\n\u003cli\u003eInternal pitch range of 8 to 14 TPI\u003c\/li\u003e\n\u003cli\u003eChipbreaker type A for controlled chip evacuation in bores\u003c\/li\u003e\n\u003cli\u003eCoroThread 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 CoroThread 266 series toolholders accepting size 16 threading inserts with left-hand, internal thread configuration.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThreading inserts should be installed by a qualified machinist following the toolholder manufacturer's clamping torque specifications.
