A drill press is mainly used to drill or expand cylindrical holes in workpieces or parts. The core operation performed on the drill press is drilling, but other possible operations include: reaming, reaming, countersinking, and tapping. There are stationary or bench-top drill presses designed to drill holes in wood or metal or plastic. Like hand-held drills, drill presses use various types of drill bits to make holes of different diameters.
But unlike hand-held drilling machines, drilling machines are stationary or desktop machines. If you only need drilling tools for small home repairs and occasional woodworking projects, a drill press may not be suitable. However, if you want to take wood or metal seriously, a drill press can make it easier for you to make precise holes, ream these holes and use sanding accessories. In this article, we will introduce you to all situations of drilling machines and help you choose the right model. Let's go!

A full-size fixed drilling machine is heavy, relatively expensive, and takes up valuable floor space in your work area. But the drill press lacks portability, and it makes up for it in terms of power and accuracy. Unlike handheld drills that rely on arm strength and operator stability to drill accurate and clean holes, drill presses are precise in design. The rotating handle controls the lowering of the spinning mechanism called the spindle (the drill bit is fixed in the chuck at the end of the spindle), and the spindle can only move vertically. This allows the holes to be created very accurately. All models have a depth stop to create holes of consistent depth.

Below we have listed a few things to consider when buying a drill press:
• Type & Size
There are two main types of drilling press types: desktop and stationary. Desktop models are smaller, lighter, and more portable. The ground model is heavier and difficult to move but has more power, capacity, and functions. All drill presses need to consider two main dimensional elements: rotation and spindle travel.
• Chuck & Table
Each drill press consists of two main components: a locking chuck and a flexible table. The chuck into which the drill bit can be inserted looks like a handheld drill bit, just bigger. But it is permanently fixed in a straight down position. You can only move it up and down; you cannot change the angle. This is an advantage over hand drills, which depend on placing the tool completely vertical to get a 90-degree hole. You can get up close, but it is by no means perfect. Moreover, if you need to drill multiple holes, you must lift the drill bit, move your body, reset the position, and then drill again. With a drill press, you can move the plank and drill holes. Faster and more accurate.
When you need to drill at an angle, a drill press is still a better choice. That's because the built-in angle gauge can be used to adjust the table of the drill press and then lock it in place. Therefore, your material will remain at the desired angle. If you try to drill by hand at an angle, you are at least slipping and getting imperfect results are much more likely.
• Swing & Spindle travel
Swing is the distance between the center column of the machine tool and the spindle multiplied by 2. If you want to use your drill press to drill to the center of the workpiece, this will determine the maximum material width you can install on the drill press. The spindle stroke boils down to the depth to which the drill press can move downward when the handle is rotated. Bench-top models can only allow vertical downward movement of 2 or 3 inches, while the best full-size units (for example, models carefully reviewed by Delta) can move 5 or 6 inches.
• Power & Speed
The best way to determine the power of a rig is to calculate the wattage. The electrical nameplates of all models show ampere and volts. Multiply them together to get watts. The higher the wattage, the stronger the tool, and the harder the material that can pass. The largest floor drilling machine used in the home workshop can provide approximately 1,000 watts of power. Desktop models usually have one-third to half of this feature. Most drilling machines have variable speeds to efficiently drill holes in different materials. High-end models provide higher speeds. Desktop models can usually provide five to six speeds, and good floor models can provide up to sixteen speeds. Why is speed important? The harder the material being drilled, the slower the required drilling speed.
Of course, the most important thing is that the job of the drill is to drill. The drill press takes a step forward by cutting precision holes of the same fixed size, angle, depth, and width, thanks to the fixed head and adjustable table of the drill. You can fine-tune the drill press and change the speed as needed. Remember, when increasing the size of the drill bit, the rotation speed of the drill bit should be reduced. If you want to drill holes in metal, you may need more powerful motors and upgrade parts for the drill.
When a hole has been drilled on a drill press, it also needs to be deburred. Often the top side of the hole may be clear, but there may still be some burrs in the bottom. The drill press attached to the deburring device should make this job a breeze.
A reamer must be used in situations where the hole must have a size of more than 1-inch in diameter. In these situations, drill the hole a little smaller than was required, and then push the reamer down at a steady and slow speed to achieve the exact result.
Some workshops allow threads to be cut into a cavity, and the drill press is ideally suited for this job. The taps and dies are very fragile and need a lot of accuracy and calculation to keep the thread aligned.
