What Is a Drilling Machine?
A drilling machine is a tool used for drilling holes in various types of wood, plastic and metal. The bench drill is bolted down for safe drilling of such materials. The pillar drill is a larger version of the bench drill and has a long column enabling it to stand on the floor. It functions the same as the bench drill but can drill larger pieces of material.
Drilling machines, also known as drill presses, are used for drilling different sized holes in a variety of materials at many different depths. It is a necessary tool in many types of industrial jobs and can perform several other functions aside from drilling.
Tapping is one of the other functions a drilling machine performs, referring to drilling holes in pipelines that are under pressure. Spotfacing refers to refining the edge of a hole to fit a bolthead or washer. Reaming makes holes more dimensional and improves the finished surface. Countersinking creates a space at the top of the hole to hold a bolt screw head in place. Counterboring makes an existing hole larger to fit the size of specific screws.
Other types of drilling machines include the upright sensitive drilling machine, upright drilling machine, radial drilling machine and special purpose drilling machine.
