A vertical drill press is a large drilling machine that stands on a very heavy steel base. A 3" steel column extends up either about 6 feet for a floor model or 3 for a bench model. At the top of this column is an elongated box with the motor at the back, driving a shaft with a 4 tier pulley above it. The front of the box contains a hollow shaft with a spindle inside it. The spindle also has a 4 tier pulley on top. The hollow shaft can be wound up and down by the side control lever. lowering or raising the drill shaft and chuck, A belt between the 2 pulleys drives the spindle and the chuck connected to it's lower end. In the middle of the column, a table, usually about 15 " square can move up and down the column to adjust work height.
Drilling capacity indicates the maximum diameter a given power drill or drill press can produce in a certain material. Typically a given drill will have its capacity specified for different materials, i.e., 10mm for steel, 25mm for wood, etc.
There are many advantages, mainly concerning the amount of different tools you can use in them. The bench drill press can take bits of up to 1/2 shank size and many of those are drill bits up to an inch wide. ( it's quite common to have large drills with reduced shanks) -Other items like large hole saws can be used, as well as 'fly cutters', which are cutting bits on the end of a movable beam. These can usually cut holes in thin materials like plexiglass sheet, up to a foot in diameter. Forstner bits up to 6 or 8 inch can be used, these cut large, flat bottomed holes for installing clocks and other instruments. Milling bits can be used to 'mill' large areas of rough surface to smoothness, and 'square hole tools' can also be used. The large drill press is a very versatile tool.
arm
The hand electric drill or the drill press.
Any machine that can drill holes is 'drilling machinery' - a hand drill, an electric drill, a drill press etc.
Although a milling machine is capable of drilling, it can be more productively achieved on a drill press or radial arm drill. Due to the complexity of the milling machine's function and the cost of its operation, it would not be feasible to use it for drilling. There are exceptions where using the milling machine for drilling a workpiece might be a better option.

A pneumatic drill press is a type of drilling machine that is powered by compressed air. It is commonly used in industrial settings for drilling holes in materials such as metal, wood, or plastic with high precision and efficiency. The pneumatic mechanism allows for smoother and more controlled drilling operations compared to manual drilling methods.
For simple drilling, the vertical drill press is faster to use.
Basic Types of Drilling MachinesDrilling machines or drill presses are one of the most common machines found in the machine shop. A drill press is a machine thatturns and advances a rotary tool into a workpiece. The drill press is used primarily for drilling holes, but when used with the proper tooling, it can be used for a number of machining operations. The most common machining operations performed on a drill press are drilling, reaming, tapping, counterboring, countersinking, and spotfacing.There are many different types or configurations of drilling machines, but most drilling machines will fall into four broad categories: upright sensitive, upright, radial, and special purpose.UPRIGHT SENSITIVE DRILL PRESSFigure 1 Upright sensitive drill pressThe upright sensitive drill press (Figure 1) is a light-duty type of drilling machine that normally incorporates a belt drive spindle head. This machine is generally used for moderate-to-light duty work. The upright sensitive drill press gets its name due to the fact that the machine can only be hand fed. Hand feeding the tool into the workpiece allows the operator to "feel" the cutting action of the tool. The sensitive drill press is manufactured in a floor style or a bench style.UPRIGHT DRILL PRESSThe upright drill press (Figure 2) is a heavy duty type of drilling machine normally incorporating a geared drive spindle head. This type of drilling machine is used on large hole-producing operations that typically involve larger or heavier parts. The upright drill press allows the operator to hand feed or power feed the tool into the workpiece. The power feed mechanism automatically advances the tool into the workpiece. Some types of upright drill presses are also manufactured with automatic table-raising mechanisms.Figure 2 Upright drill pressRADIAL ARM DRILL PRESSThe radial arm drill press (Figure 3) is the hole producing work horse of the machine shop. The press is commonly refered to as a radial drill press. The radial arm drill press allows the operator to position the spindle directly over the workpiece rather than move the workpiece to the tool. The design of the radial drill press gives it a great deal of versatility, especially on parts too large to position easily. Radial drills offer power feed on the spindle, as well as an automatic mechanism to raise or lower the radial arm. The wheel head, which is located on the radial arm, can also be traversed along the arm, giving the machine added ease of use as well as versatility. Radial arm drill presses can be equipped with a trunion table or tilting table. This gives the operator the ability to drill intersecting or angular holes in one setup.Figure 3 Radial arm drill pressSPECIAL PURPOSE DRILL MACHINESThere are a number of types of special purpose drilling machines. The purposes of these types of drilling machines vary. Special purpose drilling machines include machines capable of drilling 20 holes at once or drilling holes as small as 0.01 of an inch.Gang Drilling MachinesFigure 4 Gang drill pressThe gang style drilling machine (Figure 4) or gang drill press has several work heads positioned over a single table. This type of drill press is used when successive operations are to be done. For instance, the first head may be used to spot drill. The second head may be used to tap drill. The third head may be used, along with a tapping head, to tap the hole. The fourth head may be used to chamfer.Multiple Spindle Drilling MachineThe multiple spindle drilling machine is commonly refered to as a multispindle drill press. This special purpose drill press has many spindles connected to one main work head (Figure 5).All of the spindles are fed into the workpiece at the same time. This type of drilling machine is especially useful when you have a large number of parts with many holes located close together.Figure 5 Multispindle drill pressMicro-Drill PressThe micro drill press is an extremely accurate, high spindle speed drill press. The micro drill press is typically very small (Figure 6) and is only capable of handling very small parts. Many micro drill presses are manufactured as bench top models. They are equipped with chucks capable of holding very small drilling tools.Figure 6 Micro drill pressTurret Type Drilling MachineTurret drilling machines are equipped with several drilling heads mounted on a turret (Figure 6). Each turret head can be equipped with a different type of cutting tool. The turret allows the needed tool to be quickly indexed into position. Modern turret type drilling machines are computer-controlled so that the table can be quickly and accurately positioned.Figure 6 CNC turret type drilling machine
The two types of machine drills are the drill press, which is a stationary tool with a vertical orientation, and the handheld power drill, which is a portable tool typically used for smaller or on-the-go drilling tasks.
The Drill Press is used for drilling holes in various materials.
It drives the chuck around to enable drilling.
