- For drill with lengh to diameter ratio larger than 6xD, reduce feed by 20%
- If the RPM exceeds 10,000, a dynamic balance should be done to the system
- Maximal radial and axial runout should not exceed 0.01 mm
- As a starting value, the middle of the recommended machining range should be used, then (according to wear results),
conditions can be changed in order to optimize performance. (1) For workpiece materials list, see pages 495-524
