MACH RANGE This is a proven hammer that has been around for over 30 years and is designed for all kinds of drilling conditions but excels in overburden drilling due to the high frequency with less blow energy for drilling through unstable ground conditions. This hammer can drill smaller diameters than the standard range. This range of hammer is ideal for civil engineering.
DOMINATOR RANGE The Dominator is a higher performance hammer than the Mach Range ideally suitable for medium to higher air pressures in blast-hole applications. This design is simple with fewer components, which makes servicing and on-site maintenance easy. With a range of heavy duty models on offer this extends the life of the hammer considerably.
SUPER DOMINATOR RANGE The Super Dominator is the latest hammer in the range, specially designed for working at extreme high working pressures up to 500 psi with high penetration rates ideal for blast-hole and waterwell applications. The Super Dominator Range has a simple design with no make-up required. This hammer has an external non-return-valve for easy inspection and service and is available with a 12 spline drive system to reduce shank breakage.
GW RANGE The new GW series of DTH hammers from Halco Rock Tools offer breakthrough performance in challenging Geothermal and Waterwell applications. The robust non ported piston design dramatically improves both the piston and internal component life when drilling under a column of water. A built in choke facility allows the driller to adjust the volume of air through the hammer to optimise cuttings evacuation. GW500 and GW600 hammers are fitted with a reversible cylinder to maximise operating life and are suitable for operation at air pressures up to 30 bar (435 psi).
