It carries manufacturer part designation R166.0L-11UN01-240 1020 and belongs to the T-Max U-Lock series. The insert is manufactured from solid carbide and features a PVD-applied TiN coating for wear resistance during threading operations. It is configured for right-hand cutting at 24 threads per inch with a 60-degree included angle and a single tooth per side profile. The inscribed circle measures 1\/4 inch (6.35 mm) and the insert thickness is 1\/8 inch (3.17 mm). It is sized to Grade 1020 and carries an A chipbreaker designation. Machinists and CNC programmers select this insert for precision internal threading on lathes and turning centers.\u003c\/p\u003e\u003cp\u003eThis insert is suited for internal UN thread production in residential and commercial machining environments, including job shops, production facilities, and maintenance repair operations. It fits the T-Max U-Lock toolholder system and is appropriate for threading bores where a 60-degree UN thread form is required at 24 TPI. The right-hand orientation and laydown style make it compatible with standard internal threading toolholders in that insert family. Licensed machinists and tooling specialists handling CNC lathes and manual turning equipment are the primary installers and users of this insert.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate for rigidity and wear resistance in threading applications\u003c\/li\u003e\n\u003cli\u003ePVD TiN coating applied via physical vapor deposition for extended tool life\u003c\/li\u003e\n\u003cli\u003e24 TPI UN internal thread form with 60-degree included angle\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, laydown style for T-Max U-Lock series toolholders\u003c\/li\u003e\n\u003cli\u003e1\/4 inch inscribed circle, 1\/8 inch thickness, single tooth per side\u003c\/li\u003e\n\u003cli\u003eA chipbreaker designation for controlled chip flow during internal threading\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with T-Max U-Lock series internal threading toolholders accepting an insert size code 11 laydown insert with a 0.1102 inch hole diameter.
