An electric drill allows you to drill a hole anywhere faster than by hand. Drilling holes in walls is easy, but you need different bits for wood and board walls or concrete walls or brick walls.
If you are drilling many metals, you can lubricate the piece with cutting oil.
You rotate the operating handle faster.
more force drilling machine a drill with the 'hammer' facility and a good condition TCT drill bit. But, you do not necessarily need speed, you need acuracy
The rotating action of the drill bit makes the hole.
No, the zinc coating makes little difference to a steel drill bit.
For simple drilling, the vertical drill press is faster to use.
Any machine that can drill holes is 'drilling machinery' - a hand drill, an electric drill, a drill press etc.
Drill bits are for fitting into a drilling machine to drill holes.

A steam drill is a type of drilling machine that is powered by steam. It is commonly used for drilling holes in rocks, especially in mining and tunneling operations. The steam drill revolutionized drilling processes by increasing the speed and efficiency of drilling operations.
Same purpose as a screwdriver except it can perform drilling tasks faster and more efficiently and where repetitious work is involved. Also it has more power to turn larger screw or drill holes that can not be done by manual drilling.
On a pedestal drill the workpiece is static and the drill is in a vertical position and rotates. On a lathe the workpiece rotates but not the drill, and the drill is in a horizontal position.
The hand electric drill or the drill press.
You attach a drill bit into the chuck of the drilling machine.
