Halco Rock Tools, UK Manufacturer of DTH Hammers and Bits. Halco pioneered the development and distribution of DTH hammers in the 1950s.
The Superior 800 has been designed for high performance drilling in hard to medium rock conditions.
 
Research shows that Air Drilling can help achieve lower drilling costs, faster drill rig installation, an increased rate of penetration (ROP) with a ROP up to 5 times faster than mud, reduced hole deviation and effective pressure control through lost circulation zones.
 
Design features include a jetted backhead, variable air bleed, a bit catcher system to ensure your bits are not lost down the hole and diamond enhanced inserts.
Variable bypass porting has been added to the top adaptor.
A variable live air bleed to allow  greater volumes of drilling additives to increase up-hole velocity.
The bit catcher system ensures bits are not lost down the hole.
