With multiple hammer units CD (Cluster drills) drill holes up to 70″ or 1778 mm. As a rule of thumb, the smallest hole diameter a DTH hammer can drill is its nominal size. A 4 inch hammer will drill a 4 inch (102 mm) hole. The limiting factor is the outside diameter of the hammer, because, as hole diameter reduces, airflow is restricted.

As a rule of thumb, the smallest hole diameter a DTH hammer can drill is its nominal size. standard 102 mm (4") hammer will drill a hole down to a minimum diameter of 102 mm (4"). The limiting factor is the outside diameter of the hammer, because as the hole diameter reduces due to diameter wear of the bit, airflow is restricted.
