What is SFM in drilling?

[silversnake588]

Drilling Speeds and Feeds. The speed of a drill is measured in terms of the rate at which the outside or periphery of the tool moves in relation to the work being drilled. The common unit and term for this velocity is surface feet per minute, abbreviated sfm.

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.
