The diamond drill is a drill that is used to retrieve core samples from the ground. The drill uses a rotating hollow diamond studded bit to retrieve cylindrical rock cores. The bits are encrusted with industrial grade diamonds, the hardest natural substance on earth, and they earn the drill its name. The drilling outfit consists of the drill itself, two small gasoline driven pumps, along with drill rods, core barrels, casing pipe and tools. Diamond drilling has become a very necessary part of the mining business. Miners use the drill to find out if sufficient ore exists in the ground and the depth of the overburden covering the ore. While the diamond drill is a versatile tool, its principal use is in the exploration and discovery of ore deposits. The drill is also useful for drilling blast holes in routine mining operations.
