TungSixDrill – Flywheel housing – AH7030
IMPROVE TOOL LIFE
With the competitor’s tool, the hole diameter decreased after machining just 50 holes.
In contrast, the latest grade AH7030, which offers excellent wear resistance, effectively prevented both wear and chipping, resulting in improved machining stability.
As a result, twice the tool life was achieved compared to the conventional tool.
