Drilling is the purpose for drill in the metal /earth in depth in different shape is called drilling and boring is the size of the hole large/clean the surface is called boring.
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.
Drilling is a cutting process in which drill is used to make a hole. Drilling process usually creates rough surfaces. Therefore, reaming is done after drilling to make a good surface finish, without changing the chemical and physical properties of the material. In reaming, only 5% of the material is removed (rest is removed by drilling process done before).
Drilling centre and guided drilling get your hole in precisely the correct place.
An earthing boss and earthing lug are parts of a grounding connection. An earthing boss is in a casting that allows for the drilling and tapping of hole. A earthing lug is used to bond a wire to the ground.
It is the process of drilling a locating hole at the end of a shaft while machining between centres.
Bored is a verb used to describe a feeling or state you are in. (He, she, we, they, I) Eg.: I have nothing to do, so I'm bored. Boring is an adjective used to describe a person, object or activity (it makes you feel bored). Eg.: This documentary is very boring
A homophone for boring as in being uninterested would be boring, which means drilling a hole. In this case the spelling is the same, they sound the same but the meaning is different.
Both process enlarges an existing holewith a difference that in boring,the existing hole is enlarged throughout its length. Whereas in counterbore.enlargement is done upto a certain depth so that,say a bolt can fit in.
The homophone for drilling a hole is "whole."
Most metals are initially drilled with a narrower drill, forming a pilot hole. Then the right size drill is used to complete the drilling of the hole by widening the pilot hole.
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.
Self-tapping screws have a sharp tip that can cut its own threads into the material, while self-drilling screws have a drill bit tip that can create a hole before threading into the material.

Self-drilling screws have a drill bit at the tip that can cut through materials, while self-tapping screws have a sharp thread that can tap into materials without the need for a pre-drilled hole.

There is no difference, they are same... Hole
