Speeds and feeds - Wikipedia

The spindle speed is the rotational frequency of the spindle of the machine, measured in revolutions per minute (RPM). The preferred speed is determined by working backward from the desired surface speed (sfm or m/min) and incorporating the diameter (of workpiece or cutter). The spindle may hold the: • Material (as in a Lathe chuck)• Drill bit in a drill
