The 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 down to a minimum diameter of 102 mm (4”).
