There are many variations of drill presses, but each falls under two major categories: benchtop and floor/stationary drill presses.
Benchtop drill presses are designed to be fixed to a bench. With a quill stroke of only about 8-12’’, they are relatively smaller than floor drills. The benchtop drill press can only handle simple to fairly complex drilling tasks.
Floor drill presses are designed for heavy-duty projects. They come with quill drills of about 13-20’’ and are the most preferred option by professionals.
