This question appears to be about engineering, which is the application of scientific knowledge to construct a solution to solve a specific problem. As such, it is off topic for this site, which deals with the science, whether theoretical or experimental, of how the natural world works. For more information, see this meta post.

Edit: Ha! I just gave myself an idea for a better ice cream scooper for very cold hard ice cream, which has always frustrated me.

Is it more complicated than that? First of all every time I drill a hole in wood or any other material, shavings are produced, as well as a cylindrical empty space. By conservation of matter, the shavings should have the same total volume as the volume of the hole I just made.

The ends come in many shapes depending on the type of plunge/center cut or side/contouring cut needed. Available with two flutes, three flutes, four flutes, six flutes and even eight flutes for cutting. More flutes reduces chip load and can improve the surface finish. End mills may have cutting surfaces on one (single end) or both ends (double end). There are a variety of flute lengths and overall lengths including stub length, regular length, long flute, long length, extra long flute, and extended length.

Note this: A drill requires not only vertical force, but torque, or twisting force as well. Often you don't notice it because it doesn't require much, unless it gets stuck, then you'll definitely notice it.

End Mills are solid shank milling tools designed to use side cutting flute edges to machine most materials. There are two cutting styles. Non-center cutting (side cutting only) and center cutting (side and end plunge cutting). End mills listed here are to be considered center cutting except where non-center cutting is indicated.

Screws are different. A normal screw does not remove material, rather it deforms material by pushing it out of the way. It squeezes and wedges its way in. That's why sometimes you want to drill a smaller hole first so that the screw doesn't have to squeeze in too tight and crack the material.

The main question that motivated me to ask on here, is why a drill requires vertical force, but a router uses only horizontal force. From theoretical point of view all both objects do is rotate a screw and remove matter from a piece of wood or metal. So I need a better approximation of how these two machines work.

It sounds like you want to know what is going on at the tip of the drill bit. Well, I would say that scraping or gouging or digging, but in a circular motion, would best describe it in layman's terms. It's similar to what happens when you scoop out ice cream with with a twisting motion. It usually requires at least a little force in the direction of the hole, but sometimes the bit sort of pulls itself in, depending on the material.
