A portable drill press is a versatile and useful piece of equipment. This machine is used for drilling holes of a precise diameter, angle, and depth into wood, metal, and many other materials. Various attachments are also available for use with the press which can further expand its capabilities. When looking to purchase such a machine, there are a number of qualities a buyer should be aware of.
Any type of drill press consists of four basic parts; the table, base, head, and column. The table provides a platform where the object being bored is placed, the head contains the working drill bit, the column supports and positions both of these, and the base gives the machine support and can be fastened to either a work bench or the floor.
Such a machine is run using a geared chuck and key system. Its motor is most often a sealed ball-bearing design that is mounted near the back of the column. The capacity or size of the press depends on the distance from the front of the column to the chuck's center, this is referred to as the "throat depth" and in most cases measures from 8 to 17 inches.
As a rule of thumb, the capacity of the press is equal to twice its throat depth. Another name for this measurement is the "swing" which denotes the largest size of material the machine will be able to reach the center of and bore. It can be at most the size of the swing and double the throat depth.
There are two basic types of drill presses, bench-top and floor models. The former usually range from 23 to 48 inches in height, can bore holes 10 to 12 inches deep and has a swing of 8 to 12 inches, it is best for simple projects, is typically less expensive and easier to store. The latter, is larger, standing 66 to 75 inches tall and has a more powerful motor and swing of 13 to 20 inches, allowing it to bore more types of materials. This type also comes with more extra attachments.
Specialty models with particular abilities are also on the market, such as the magnetic and radial types. A radial press offers an increased swing of at least 24 inches and can drill materials at varying angles. The magnetic press is most suitable for boring structural steel as it has superior power and usually a swing of 4 to 8 inches or more.
The size of the motors varies as well from one model to another. They normally range between 1/4 and 1 in horsepower, as this number increases so does the machine's ability to drill thicker materials. The "quill travel" is another aspect which refers to the boring depth the press has, the higher it is the deeper it will bore. The speed settings are usually adjustable too.
It can also be helpful to select a portable drill press which has a depth block, fences, and pivoting table. With a depth block, one can set a precise drilling depth. Fences, enables the user the block the piece being drilled and permits the drilling of multiple holes. If the table position can be easily adjusted, it will better facilitate drilling irregularly shaped pieces.
