  • DTH Bits - Rock Drilling Tools

    Convex Face DTH Bit For medium soft to medium hard rock in good ground conditions where maximum penetration rate is desired. The convex design will handle abrasive formations better than a concave or flat design. The convex design also enables the use of greater insert density for aggressive spherical, conical or ballistic tipped bits.

    2021-9-13u2002·u2002The optimum range of hole size for DTH drilling is 90 mm (3.5') to 254 mm (10'). Smaller holes are generally drilled using tophammer drill rigs, and larger holes generally use rotary drill rigs. As a rule of thumb, the smallest hole diameter a DTH hammer can drill is its nominal size. i.e. standard 102 mm (4') hammer will drill a hole ...
