DrillMeister – Valve connecter- DMF
IMPROVE TOOL LIFE
The drilling process was previously carried out using a U-Drill, but the short tool life was a bottleneck in the process due to machine down time. By adopting the DrillMeister DMF head, high feed processing has been achieved, significantly improving tool life to 3.4 times longer than before and avhide reduce machine down time.
