Halco Rock Tools, UK Manufacturer of DTH Hammers and Bits. Halco pioneered the development and distribution of DTH hammers in the 1950s.
The Dominator 500 is suitable for drilling at a wide range of air pressures making it a class leader in performance. The Dominator 500 is ideal for use in Waterwell and Drill & Blast applications.
 
Dominator 500 has a one-piece top adaptor with N.R.V fitted to eliminate shimming and it has no liner which increases the piston blow energy.
 
Dominator 500 uses a few tools for maintenance, making it easy to maintain and service.
One piece top adaptor with N.R.V (Non-Return-Valve) reduces internal parts and easy maintenance.
Revised chamber volumes and cycle timing to optimize performance.
Simplified piston geometry for improved balance and location within cylinder.
Air Consumption
 
Suitable for operation at air pressures of 100- 507 PSI (7-35 bar).
 
Drilling diameters of 127 - 165mm (5 - 6 1/2").
Halco 5 shank reduces contact stresses and wear rates.
