- Feeds – Feed rates for drilling are governed by the drill diameter, machinability of materials and depth of hole.
- Speeds – The speed of a drill is determined by the rate which the outer periphery of the tool rotates in relation to material being cut. In general, the SFM at which a drill will operate is within a range based upon the workpiece material, its condition, hardness and depth of hole. It is usually advisable to start the drilling process at a slower SFM and then increase to the maximum.
- RPM = (SFM x 3.82) divided by TD = Revolutions Per Minute
- SFM = RPM x TD x .262 = Surface Feet Per Minute
- TD – Tool diameter in inches
