Halco Rock Tools, UK Manufacturer of DTH Hammers and Bits. Halco pioneered the development and distribution of DTH hammers in the 1950s.
The Dominator 800 is a general purpose hammer suitable for a wide range of air pressures.
 
A low to mid range air volume hammer with a one piece top adaptor. The Dominator 800 has a unique air distributor finger which is integral with the top adaptor and reduces requirements for shimming.
 
One piece top adaptor reduces internal parts as no make up is required. External N.R.V (Non-Return-Valve) for easy maintenance.
Revised chamber volumes and cycle timing to optimize performance.
Simplified piston geometry for improved balance and location within cylinder.
Heavy duty cylinder for extended hammer life.
