TungSixDrill – Cylinder head for ship – AH7030
IMPROVED TOOL LIFE AND COST EFFICIENCY
The conventional drill had a short tool life due to insert chipping. In contrast, the latest AH7030 grade, which offers excellent chipping resistance, achieved stable and predictable wear without chipping, resulting in a 1.7 times longer tool life. Furthermore, TungSixDrill, featuring 1.5 times more cutting corners than the conventional insert, successfully reduced tooling costs by 50%.
