Our state-of-the-art DTH hammers are meticulously designed for superior performance in blast hole drilling and blasting. These tools are primarily utilized across the industries of mining, marble quarrying, well drilling, and various construction projects, ensuring unparalleled efficiency and effectiveness.
DTH hammer drill bits, crafted for excellence in geological exploration, are indispensable in sectors like coal mining, water conservancy, hydropower projects, as well as infrastructure like highways, railways, bridges, and general construction.
Advantages:
Extended Drill Longevity: Crafted from premium alloy materials, our drills boast a superior lifespan, outperforming similar products in the industry with ease.
Unmatched Drilling Efficiency: Thanks to the wear-resistant drill buttons, our tools maintain sharpness, dramatically boosting the drilling speed and productivity.
Consistent Drilling Speed: The bit is engineered to scrape and cut seamlessly through rock, ensuring stable and reliable performance.
Exceptional Performance: With robust wear resistance and excellent diameter protection, our drill bits maximize the efficiency of cutting teeth, delivering outstanding results.
Versatile Application: Tested extensively, our bits excel in drilling through a variety of materials such as carbonate rock, limestone, chalk, clay rock, siltstone, and sandstone, handling both soft and hard rock (up to 9-grade drill ability) with remarkable efficacy. Notably, they perform exceptionally well on rocks of 6-8 grade hardness.
The transformative impact on rock drilling is particularly notable, showcasing our bits' superiority over ordinary options.
Our cutting-edge products are engineered from high-grade alloy materials, featuring wear-resistant drill buttons and stable drilling speeds. They deliver high drilling efficiency, superior diameter protection, and an extended drill bit lifespan, setting a new standard above similar products.
