These TCGT series triangular internal boring inserts adopt high-grade CBN cubic boron nitride cutting tips with red-tip design, specially for quenched steel and high-hardness heat-treated parts. Available in multiple specifications, they match standard precision boring bars perfectly.
The ultra-hard CBN material provides exceptional wear resistance and thermal stability, delivering stable boring performance and excellent chipping resistance on hardened workpieces. It ensures premium surface finish and highly consistent dimensional accuracy for inner bore finishing.
Perfect for precision internal finishing of heat-treated quenched steel parts on CNC lathes and Swiss-type machines. Its extended service life cuts tool-change downtime, reduces tooling costs and effectively boosts high-precision bore machining efficiency.
