Profile: China Drilling Geological Equipment Ltd. specializes in the design and manufacture of diamond drilling tools. We offer our products to engineering, geotechnical exploration, mining exploration, oil exploration and hydropower station grouting projects. We produce a wide range of drilling tool including synthetic diamond core bits, natural diamond surface-set core bit, PDC bits, casing shoes, reaming shells, wireline barrel assemblies and other drilling tools. These are all manufactured to the strictest quality standards and are used around the world in a great variety of applications. Impregnated diamond core bits can penetrate a broad range of formations from the softest to the hardest rocks. They are manufactured with synthetic diamonds mixed evenly through a tungsten carbide matrix. The turbo water and gear type diamond core bits are drilled to hard rock with low drilling pressing. The surface set diamond core bits are set with the premium natural or synthetic diamond. A serious size natural diamonds are varied with the rock formation, from soft to very hard, that ensures maximum cutting efficiency. The tapered step crown design provides good stability. The discharged diamond core bits, of large water and big size stone, are designed to cut the soft & loose rock.
