Down the Hole Hammers (DTH) | Complete .

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"). 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. Maximum hole size for production drilling is the ...
