    In DTH drilling, the rock drilling bit is a continuation of the shank, which the rock drill piston strikes directly. Since the piston is in direct contact with the drill bit, little energy is lost. This gives DTH drilling a nearly constant penetration rate regardless of hole length.

    DTH bits are paired with their corresponding hammers (by drilling hole diameter and spline configuration). Customers can customize their DTH bits in various ways, such as changing the tungsten carbide insert profile (spherical, ballistic, etc.), face profile (flat face, concave, convex, etc.), and flushing holes.

    • Medium to large size drilling diameters
    • Works in high pressure range, capable of drilling deep hole lengths


    Competitive Advantage

    • High grade tungsten carbide inserts
    • Bit bodies manufactured from high grade steel and processed using state-of-the-art CNC machinery and heat treatment


    Applications of DTH Bit

    • Underground mining
    • Tunneling

    • Quarry benching operations
