To determine the surface feet per minute (SFM) for drilling, multiply the cutting speed by the diameter of the drill and convert the result into feet per minute using a standard formula.
The Drill SFM Calculator is a vital tool for machinists and engineers to optimize drilling operations by calculating the surface feet per minute (SFM). SFM represents the speed at which the cutting edge of the drill moves through the material, ensuring efficient and precise drilling.
Formula
| Variable | Description |
|---|---|
| SFM | Surface Feet per Minute |
| RPM | Revolutions Per Minute |
| Drill Diameter | Diameter of the Drill (in inches) |
