Request a Quote
Down-the-hole hammers for deep hard rock drilling applications with high air pressure
The SPM S Series deep-hole DTH hammers are widely applicable and suitable for efficient drilling of tough rocks in hydrological water wells, geothermal wells, oil and gas wells, coalbed methane wells, and other engineering projects.
Features
- Resistant to clogging: Testing and user feedback indicate a very low probability of blockage even when encountering water.
- High efficiency: Delivers large single-impact energy and high impact frequency, improving operational efficiency by over 15% compared to previous products.
- Long service life: Components are treated for fatigue resistance and corrosion protection, extending service life by approximately 20% over previous models.
- Reliable cuttings removal: Designed for deep-hole drilling, adjustable air intake ensures efficient removal of cuttings.
