DTH HAMMERSTOWNSEND, NSW 2463

Description

In other applications, like foundation drilling, DTH hammers can be used with single bit in hole sizes up to 750 mm (30?). 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. Maximum hole size for production drilling is the nominal hammer size plus 1 inch, so for a 4 inch hammer the maximum hole size is 5 inch (127–130 mm).
