  • Parameters for the use of Drill Bits 1. Rock Drilling

    Basalt has a much higher fracture toughness because the inter-grown crystals are so much smaller and a propagating fracture meets crystal boundaries more often. Abrasives Rock abrasiveness is a rock property that is important in drilling with Diamond Bits. The abrasiveness can affect both penetration rate and the life of the Bit.
