DrillMeister -Tube sheet – DMC
IMPROVE TOOL LIFE
Existing drills required pilot hole drilling, which resulted in long process times. Another issue was short tool life. DrillMeister DMC unique self-centering shape means that pilot holes are not required even for drilling over 5xD. As a result, one-shot drilling is possible, and tool life has been extended by 1.7 times.
