Changsha Miracleland Import & Export Co., Ltd is a professional and credible international trade company. We are specialized in manufacturing and exporting drilling tools and equipment for mining exploration, soil investigation, water well construction, and etc.

Impregnated bits can penetrate a broad range of formations from the softest to the hardest rocks. They are manufactured with very small, high quality synthetic diamonds mixed evenly through a tungsten carbide matrix. During drilling the matrix wears away evenly resulting in continuous exposure of new, sharp diamond points throughout the life of the bit.
All impregnated bits have T.C. and diamond gauge protection. The optimum diamond size, concentration and matrix composition varies according to the hardness and abrasiveness of the rock formations to be drilled.

We had been making great efforts to develop various drilling tools to meet the different needs for our customers. The drilling tools including core bits, diamond core bits, non-coring bits, reaming shells, casing shoes & casing bits, core barrels, overshots, drill rods, casing tubes, SPT tools and other drilling tools.
