Drilling Speed and Feed Calculator

Drilling is a machining operation in which a cutting tool with sharp teeth, such as a twist drill, rotates and feeds into the workpiece axially, forming a hole with a diameter equal to that of the tool. The motion of the cut is specified through several parameters, beginning with the cutting speed and cutting feed, which are selected based upon the specific cutting operation, workpiece material, tool material, and other cutting parameters. The speed and feed calculator can be used to determine the spindle speed (RPM) and feed rate (IPM) for the specified cutting conditions, as well as the cut time for a given cut length.
