It all depends on what you are constructing. If the hole is required for some kind of fastener, if it is too small the fastener will not slide through. If to slack, the unit may fail when put into use, by allowing movement and wear, causing early fatigue.
During specialist construction (say for aircraft) some holes are drilled slightly under size and then reamed out, for a perfect fit.
For wood screws, the pilot hole must allow enough material for the thread to grip, but without pinching the screw, making it difficult to tighten up.

Why is it best to use the right size of drill it in boring holes?
Because you presumably want your hole to be the right size, not too small or too big.
Why it is the best to use the right drill bit in boring holes?
Because you presumably want your hole to be the right size, not too small or too big.

Because you presumably want your hole to be the right size, not too small or too big.
Why is it best to use the right size drill and boring tools?
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.
What type of tool is best for drilling holes in wood?
A power drill with a drill bit is the best tool for drilling holes in wood.
What is the best tool for making holes in wood?
The best tool for making holes in wood is a drill.
What is the best type of drill bit to use for making holes in wood?
For making holes in wood, the best type of drill bit to use is a twist drill bit. These bits have a sharp point and spiral grooves that help to remove wood chips as you drill, resulting in clean and precise holes.
What is the best tool for drilling holes efficiently and accurately?
The best tool for drilling holes efficiently and accurately is a drill press.
What is the best tool for drilling angled holes?
A drill press with an adjustable table is the best tool for drilling angled holes.
What type of drill bit is best suited for creating holes in various materials?
For creating holes in various materials, a twist drill bit is best suited due to its versatility and ability to work on different surfaces effectively.
What is the best technique for drilling precise holes using a 2mm drill bit?
The best technique for drilling precise holes using a 2mm drill bit is to start with a pilot hole, use a drill press for stability, and apply consistent pressure while drilling at a slow speed.
What is the best guide for drilling angled holes accurately and efficiently?
A drill press with an adjustable table and a jig is the best guide for drilling angled holes accurately and efficiently.
