DTH Hammers & Bits II
DTH cluster drills consist of several smaller DTH hammers which are housed and driven in a circular steel barrel. The main advantage is that smaller and cheaper DTH hammers with less air consumption are combined to drill holes in hard rock up to 1830 mm diameter. Our DTH cluster drills and accessories can also be used for RCD (reverse circulation drilling).
Our Overburden Drilling Systems are the optimum solution if temporary or permanent steel casings have to be installed by drilling in hard rock. Special extending and retracting drill bits undercut the wall thickness of the steel casing so that the casing can be easily sunken down to the required depth simultaneously with the drilling operation.
