A Drill Press is a tool used for drilling holes in furniture at home or in office. This tool is most commonly used in construction, wood work, and metal work. The drill press has a rotating bit used to make hole and a chuck at its end for gripping option.

The Uses of Drill:
o Twist drilling
o Oil drilling
o Masonry Drill
o Bench Drilling
o Pillar drilling
o Pedestal drilling
Two Types of Drill:
1. Manually Powered
The Manually powered drill runs on electricity or compressed air.
2. Minority Drive Engine
The Minority Drive engine is typically driven by an internal combustion engine. Earth drilling is an example of this type.
The Main Parts of Drill Press:
1. Base
2. Column
3. Table
4. Spindle
5. Drill Head
The Base is the head of the drill press. It usually has a set of three handles. These handles radiate from a central hub. It can be moved vertically, by the spindle and chuck when turned for adjustment. The handle is aligned parallel to drill press the axis of the column.
The Table is generally moved by a pinion or a rack. It may be the counterbalance from the axis of the spindle and can be positively rotated to position perpendicular mainly to the column part of the drill. This can be adjusted vertically.
The size of drill press is measured relative to the swing. Swing is also known as the twice throat distance. The throat distance is the measurement from the center of the spindle to the closest pillar edge. For instance, a 16-inch drill press must have an 8-inch throat distance.
The Advantages of Drill Press:
o mechanical benefits
o More secure operation
o accurate drilling
o adjustable speed
o Continuous variable transmission engine
The drill press required less effort in applying the drill to the work piece. It gives the advantage of mechanical work by the movement of the chuck and spindle through level working on a rack and pinion. Work becomes less tiring for the user.
A table and a vise or clamp locks the work piece securely. This fixed position allows for more accurate drilling especially in repetitive tasks. The vise in drill press is a motorized screw used for holding or clamping a work piece. These apparatus allows work to be performed with tools of saw, plane, drill, mill, screwdriver, and sand paper.
The drill press can configure a change in speed by manually pulling the belt across a stepped arrangement of pulley. Other drill press consists of third stepped pulley to adjust speed. Modern drill press uses a variable speed motor conjunction with the system of stepped pulley. These are the continuous variable transmission with a sort of wide range chuck speed while the machine is running.

Field assembly
Whether you want to drill hinge cup recesses, cut batches of wood plugs, hog out a mortise or countersink pilot holes a drill press can do all the work for you. A drill press is versatile and accurate and it's a tool every woodworking workshop should have. Before purchasing a press drill to use for any of your projects there are factors that you need to consider first. After testing a couple of models I'll argue that choosing the best Drill Press is based on the following factors:
Technical specifications
Technical aspects of any drill are rated based on motor power, drill speed, quill travel (drilling depth) and the swing (working column height). Working with a compact drill press with a 8 inch swing, five speeds, a spindle travel of 2 inches, 1/3 horsepower 6 1/2 workable, 45 degrees tilting power can be great but there is something more than that which you might need for a professional workshop. I personally prefer working with a drill pres that has a 13 to 15 inches swing, a table size of 13x 10 inches, a 3/4 horsepower, 16 speeds and a range (preferably 200 to 3600 rpm) because it allows me to get the precise selection I need when handling different wood materials and drill bit sizes. Also working a drill with such high technical ability delivers an impressive work in the workshop hence more ideal for professional work
Build quality
When you discover your drill press is vibrating too much, then it is likely to create inaccuracies. The drill press could be dangerous as well. Right from its top to the bottom, the build up quality should be proper for use in the workshop. Based on experience I would recommend a brand with a cast iron base, table and even drill heads. A 150 pounds drill with extreme rigidity, plenty of power, little run-out of the chuck (with the help of high quality ball bearings on the spindle) can be great for any hobby wood worker to a professional workshop wood worker.
Features
Right from the precision laser slighting to the depth gauges, there are many features that differentiate a top drill presses from also-rans. An ideal press drill should have a fairly standard angle gauge, micro-adjustable and independent depth stop and depth scale, twin laser system for more accuracy and a self-tensioning system for delivery of more power.
Price
With great difference in the technical specification and build up quality, the price of the different prices might vary largely. If you are planning to buy a versatile high quality that will deliver an impressive work, you should go for highly priced drill presses. Top performing are rigid, more durable and have greater capacities.
Chuck quality
Chuck quality might vary from one machine to another but it is something that matters big time. Find a chuck that can operate smoothly over its (whole) range of adjustment. Also, getting some additional information on runout -in the spindle & chuck assembly-can help you know how much a bit wobbles as it turns. The less the runout, the better.
Conclusion
When selecting the best brand of drill press in the market, find one with superb performance or functionality, one with the best value of money and a press drill that has outstanding features as well as technical specifications. You can compare the available brands online or locally to find out the ones performance greatly and going at reasonably lower prices
