Halco Rock Tools, UK Manufacturer of DTH Hammers and Bits. Halco pioneered the development and distribution of DTH hammers in the 1950s.
The Superior 1250 accepts DHD112S shank bits and is equipped with an oversized chuck to accomodate this shank.
 
This oversized chuck protects the cylinder and prolongs life.   The Superior 1250 has a pin drive arrangement to prevent metal to metal contact thereby minimising spline wear and damage which can result in drill bit shank failure.
Standard design features include a jetted backhead, variable air bleed, and a bit catcher system to insure your bits are not lost down the hole.
Bypass porting has been added to the top adaptors to increase uphole velocity if required.
Variable choke to adjust live air volume.
The bit catcher system retains the bit in the cathcher in the case of shank failure.
