A drilling machine is a tool used for drilling holes in various materials, such as metal, ceramic wood, or plastic. It can be either portable or stationary. A drilling machine is very versatile and can be used to make a variety of hole types and geometries as listed below: Drilling: The most common use of a drilling machine is making either blind or through holes in a workpiece. Reaming: Used to finish an already-drilled hole, improving both its dimensional accuracy and its surface finish. Countersinking: After a hole is drilled it may be necessary to create a countersink in the workpiece. A countersunk hole has a conical cutout to accommodate the head of a fastener that must be flush with or lower than the surface of a finished part. Tapping: Once a hole has been drilled, it may need to be threaded to accept a threaded fastener like a screw or bolt. A tap can be attached to the machine and used to cut internal threads. Boring: A drilling machine can be used to increase the diameter of an existing hole through the process of boring. Counterboring: A counterboring tool is used to create a shallow, enlarged cylindrical cutout so that a fastener’s head will fit flush with or below the work surface.
