High penetration rates and long life are possible in a wide range of formations, from medium hard to hard and extremely hard, either fractured or competent. This is all achieved by the correct formulation of the matrix, the use of the best raw materials available and well controlled manufacturing process. The bits are color coded according to the application in 12 different matrix - diamond combinations, specifically designed to attain the best performance. 1.800.746.0258
