MACH 60 DTH Hammer for Rock Blast & Water Well Drilling - 6" Diameter, 28.5m³/min Air Consumption
Proven hammer design with over 30 years of field performance, engineered for diverse drilling conditions with exceptional capability in overburden drilling. Features high frequency with reduced blow energy for stable operation in unstable ground conditions. Capable of drilling smaller diameters than standard ranges, making it ideal for civil engineering applications.
High-performance hammer optimized for medium to high air pressures in blast-hole applications. Simplified design with fewer components enables easy servicing and on-site maintenance. Heavy-duty models available for extended operational life.
Latest generation hammer designed for extreme high working pressures up to 500 psi, delivering superior penetration rates for blast-hole and water well applications. Features simple design with no make-up required, external non-return valve for easy inspection, and 12-spline drive system to minimize shank breakage.
Advanced DTH hammer series engineered for challenging geothermal and water well applications. Robust non-ported piston design significantly enhances piston and internal component life during water column drilling. Built-in choke facility allows air volume adjustment for optimal cuttings evacuation. GW500 and GW600 models feature reversible cylinders for maximum operating life and support air pressures up to 30 bar (435 psi).
