Because diamond drill bits are used to drill in extremely hard materials, it is very important to use proper drill pressure to keep from overheating the drill bit.  Excessive pressure is merely converted to heat energy and can burn up a bit or cause heat fractures in the material being drilled.

Water must be used for lubrication.
