A holistic consideration of twisted deep hole drilling tools for hard cutting operations.
- el">•
Tool’s symmetry is of vital importance for the bore hole quality and the performance.
- el">•
Asymmetries are caused by manufacturing flaws with corresponding tolerances in the range of a few microns.
- el">•
Only highly symmetric tools result in high process reliability without tool failure.
- el">•
Slightly asymmetric tool tends to wear out unequally during the tool life time and premature failure results.
