Halco Rock Tools, UK Manufacturer of DTH Hammers and Bits. Halco pioneered the development and distribution of DTH hammers in the 1950s.
The Super Dominator 450 has been specifically designed for high production drilling in blast hole applications.
 
The hammer is robust and has few parts, making it user friendly and reliable.  The Super Dominator 450 is fitted with a N.R.V (Non-Return-Valve) in the top adaptor for a quick, easy inspection and maintenance operation.  A fixed air distributor in the top adaptor means the 450 requires no shimming which simplifies servicing. It also has no liner which increases the piston power output.
 
The Super Dominator 450 utilizes Halco's 12 spline shank which has a simplistic robust geometry combined with increased drive contact area.
One piece top adaptor reduces internal parts.  No make up required.  External N.R.V for easy maintenance.
Revised chamber volumes and cycle timing to optimize performance.
Simplified piston geometry for improved balance and location within cylinder.
Revised cylinder porting to maximise air flow efficiency.
The Halco 4.5 shank reduces contact stresses and wear rates.
Air Consumption
 
Suitable for operation at air pressures of 100-507 PSI (7-35 bar).
