A drilling machine operation is the process of creating, enlarging, or finishing holes in a workpiece using a rotating cutting tool called a drill bit. The machine works by rotating the drill bit at high speed while applying downward pressure to cut into the material. Common operations performed include drilling, reaming, counterboring, countersinking, tapping, and spot facing. Drilling machines are widely used in metalworking, woodworking, and construction due to their accuracy, efficiency, and ability to produce holes of different sizes and depths.
