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 LE has been designed for high pressure performance drilling in blast hole applications.  Its operating characteristics are particularly suited to soft and un-consolidated ground conditions.
 
The one piece top adaptor improves reliability and is easy to service, whilst the outer cylinder is hardened for maximum durability and can be reversed to increase service life.
 
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.
