Assumptions and limitations
Metric drilling relationships. Enter manufacturer cutting speed and feed per revolution for the actual drill, material and setup. Examples are not material recommendations. Machine RPM limits, coolant, rigidity and chip evacuation are not inferred. A 10 mm drill at 30 m/min requires about 955 rpm; 0.1 mm/rev gives about 95.5 mm/min.
