Drilling Speeds and Feeds - University of Florida

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. Every tool manufacturer has a recommended table of sfm values for their tools.
