DTH Hammer Classic Mission 30/40/50/60/80 hammer in quarries and shallow water well drilling

Product Description

The optimum range of hole size for blast hole drilling with DTH is 90 mm to 254 mm (3 ½"–10"). Smaller blast holes are generally drilled using tophammer, and larger holes generally use rotary machines.

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 (Clusterdrills) drill holes up to 70" or 1778 mm.


All products are interchangeable with various products manufactured by Atlas Copco.
