Surface feet per minute. SFM is a combination of diameter and the velocity (RPM) of the material measured in feet-per-minute as the spindle of a milling machine or lathe. 1 SFM equals 0.00508 m/s (meter per second, the SI unit of speed).

Subsequently, question is, what is a good RPM for a drill? Recommended Speeds for Carbide Tipped Holecutters

Size Steel Stainless Steel 11/16 to 13/16 in. 700 - 1000 RPM 300 - 700 RPM 7/8 to 1-3/16 in. 500 - 800 RPM 200 - 450 RPM 1-1/4 to 1-9/16 in. 300 - 600 RPM 175 - 315 RPM 1-5/8 to 2 in. 200 - 500 RPM 120 - 225 RPM
Subsequently, one may also ask, what is SFM cutting speed?

Cutting speed is the speed in linear feet per minute or Surface Feet per Minute (SFM) that a given tooth (flute) on the cutter will be moving when it cuts through the material. All materials have a documented SFM or cutting speed. Think of it like a minimum and maximum speed limit on a highway.
