Drilling is a machining process that involves the subtractive manufacturing of cylindrical holes in solid material using single- or multi-blade cutting tools known as drills. During drilling, the primary (rotary) motion is performed by the tool or workpiece (lathe drilling). The feed motion is performed by the tool or the workpiece in a direction parallel to the drill axis.
