Please note:
Stainless steels: centerdrill core hole diameter +0.1 mm for M8 and higher:
10-20% lower speed. Non-ferrous metals: up to 50% higher speed. Feed rate: 150 mm/min

Depending on the application and machine conditions the process speeds may also clearly vary from the above information. Our application technicians are pleased to consult you.
