It is the process of drilling a locating hole at the end of a shaft while machining between centres.
Drilling centre and guided drilling get your hole in precisely the correct place.
A sensitive drilling machine is an upright drilling machine. However, a radial drilling machine is also considered a sensitive drilling machine.
Conventional Drilling is the drilling of a vertical well through reservoir rocks to TD. Directional drilling is the drilling of a non-vertical well horizontaly through a source rock.
A small indentation made on metal prior to drilling is called a "pilot hole" or "center punch mark." This indentation helps to guide the drill bit, preventing it from wandering and ensuring accurate placement of the hole. It also reduces the risk of the drill bit slipping on the metal surface, leading to cleaner and more precise drilling results.
Typically a center punch tool is used to aid in drilling. The impression made by a center punch into wood, plastic or metal marks the area to be drilled and helps the drill stay on course as it goes through the material. The traditional center punch is used with a hammer and the automatic center punch uses a spring tension mechanism to create a force hard enough to make the indentation. Read on to learn how to use a center punch.

To find the center of a circle for drilling, you can use a compass to draw two intersecting lines across the circle. The point where the lines meet is the center of the circle. You can then mark this point for drilling.

It guides your drill so that it doesn't drill off center. Drilling into a flat surface with a standard drill is not going to work or in the rare occasion it does will atleast give u a headache trying.
A drill centering tool is used to accurately position a drill bit at the center of a workpiece before drilling. This tool helps ensure that the hole is drilled in the correct location and at the desired angle, resulting in precise and accurate drilling. By guiding the drill bit to the center of the workpiece, the centering tool helps prevent errors and improves the overall quality of the drilling process.
Primarily, the lack of a good reason to do so, and the extreme heat.
For drilling through hardwood, I recommend using a brad point drill bit. These bits have a sharp point that helps to center the bit and prevent it from wandering, making them ideal for drilling precise holes in hardwood.
