TungSixDrill – Bush – AH7030
IMPROVED COST EFFICIENCY
Compared with the conventional 4-corner insert drill, the TungSixDrill, featuring a 6-corner insert design, successfully reduced tooling costs. In addition, while the previous tool required two different inserts for the central and peripheral cutting edges, TungSixDrill uses a common insert for both positions, simplifying tool management. Tool life was also equivalent to or better than that of the conventional drill.
