Pillar/column drills are fairly small, appropriate for most woodworking and small metalworking tasks; the kind of thing you can hold in your hand. They are low power, usually under 1 hp. Pillar drills are geared toward higher speeds, topping out at 2000 to 3000 rpm; they are suited to smaller drills. They do not have the power to turn a large drill in metal. Most will advertise a maximum drill diameter of 3/4" in mild steel. The neck depth, or distance from the drill spindle to the pillar that's holding the drill up, is short, usually around a foot deep. The drill has a spindle which can extend about 6" on most machines, making the maximum depth possible just under 6".
The name comes from how the drill head is mounted. The drill head sits directly on the top of a long pole, usually about 4" in diameter, which goes down to a stand on the floor. It is thus standing on top of a pillar. There is a work table also mounted to the pillar, and this is where most work on the drill is held.
A radial drill, by contrast, is mounted on a very large column - a foot or more in diameter even on tiny radial drills. Large radial drills can have 30" or larger columns, compared to the 6" on some of the biggest pillar drills. On this column is mounted an arm that can swing 360 degrees (hence, radial drill). The arm has a rail on it, and the drill head is mounted on the rail. This way, you can swing the arm out of the way, drop a very large casting on the ground, and then swing the arm back into place.
If a table is required, there are special metal boxes that mount to the floor and provide an elevated work surface. The movements on a radial drill are roughly square - small radial drills have about 4 feet of movement of the head along the rail, and the rail can usually travel about 4 feet up and down the column to position the head. A larger radial drill, one with an 8 or 10-foot arm, would usually have a little extra column space, say to 12 or 15 feet tall. The head itself can be anywhere from 5 hp on a small machine, to 50 hp on a large machine - this means the drills can be very large, 4 inches and over, and smaller drills can be pushed very hard. The spindle is geared for low speeds, and most radial drills can't go above 500-1000 rpm at the very maximum. The spindle is much longer, and being able to drill 15-20 inches is not uncommon even on smaller machines. Spindle length increases with machine size. Most radial drills have fully automatic feeds. Rather than physically pulling down on the drill, you flip a lever and the machine begins to feed the drill down into the work automatically. There may be stopped controls so that the machine can be set to halt the drill and return to the start position. Radial drills sometimes have coolant pumps to force coolant through tiny channels in larger drills for this purpose, to keep the drill cool during heavy cuts.

Answer:
Radial drilling machine
- These sorts of drilling systems are designed for making hollows on huge and heavy workspaces. it helps a radial arm withinside the column which lets the desk transport up and down if you want to drill workpieces of various heights. It is likewise used as a rock drilling thing that creation groups can effortlessly use.
- The radial drilling system using the mechanism is at separate feed and extraordinary speed. The function of the system is adjusted using sliding the drill head and the gateway of the arm.
Piller drilling machine
- Pillar drills (additionally called drill press machines) are flexible machines that may be used on an extensive variety of substances wherein unmarried hollow drilling is required.
- The head is diminished vertically and plunges into the cloth through a hand lever and the desk may be adjusted to fit various sizes of cloth
