Diamond Drilling or Exploration Diamond Drilling makes use of an annular diamond-impregnated drill bit attached to the end of hollow drill rods to cut a cylindrical core of solid rock (core samples). Diamond size and matrix can be varied according to the hardness of rock needing to be cut. Holes within the bit allow water to be delivered to the cutting face. This provides lubrication, cooling, and removal of drill cuttings from the hole.
