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 500 is a class leader in performance and is suitable for dilling at a wide range of air pressures but excels at high working pressures.
 
The Super Dominator 500 has a one piece top adaptor with a N.R.V. (Non-Return-Valve) fitted for easy inspection and service. An integral finger reduces maintenance and eliminates shimming.
 
The Super Dominator 500 is ideal for blast hole drilling applications and is easy to maintain and service requiring only a few tools.
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.
