1) The above values apply when coolant is used in vertical machine & horizontal machine, when drilling in stainless steel and hard to cut material using pecking.
2) Adjust drilling condition when unusual vibration or different sound occurs.
3) Recommended feeds and speeds are starting points only. Actual performance will be determined by the material, the condition of equipment being used and coolant.
Formulas: RPM = SFM x 3.82 Feed Rate (in/min) = RPM x IPR
