Rock drilling tools manufacturer ProDrill: Poly-crystalline diamond compact/composite(PDC) drill bits are an effective tool for drilling into homogeneous sedimentary rock formations such as shale, sandstone, dolomite, limestone etc. This type of rock drill bits use the shearing scraping or shaving action when encountering the rock formation. PDC bits are the most rigid of all the diamond tool materials. They are made by combining layers of poly-crystalline diamond (synthetic diamond) with substrate of carbide at high temperature and pressure.
ProDrill Rotary drilling tools offering high quality PDC drill bits which have been specially designed to withstand higher impact and abrasion. Our PDC bits are of premium quality being used extensively in water bore drilling, oil and gas exploration.
