DrillMeister DMM head -Ni base component –
IMPROVED TOOL LIFE
The DMM geometry outperformed the current drill in Ni-based alloys.
Using the same cutting parameters, tool life was extended by 1.4 times.
The existing drill head had been a special item dedicated to Ni-alloy drilling, whereas we achieved even better performance with a standard item.
