Experience unmatched drilling efficiency with our RC Hammers Bits and DTH Hammer Bits, engineered for superior Reverse Circulation and rock penetration. These tools redefine rock drilling performance.
Our DTH Drill Bits are crafted from premium-grade nickel-alloy steel, significantly enhancing durability and wear resistance. Adhering to rigorous heat treatment standards and incorporating specialized "stress relief" processes, these bits deliver reliable and consistent performance.
Our DTH hammer bits are meticulously engineered to maximize performance and deliver exceptional hole characteristics, setting a new standard in the industry:
1. Leveraging extensive experience with traditional hammers and integrating the unique features of reverse circulation hammers, we have optimized the internal structure for ideal energy transfer. This ensures rapid, smooth, and uninterrupted sampling with our hammer drills.
2. The simplified internal structure, composed of high-rigidity components, guarantees the hammer's longevity and facilitates straightforward maintenance.
3. The integrative design of the collection tube allows for easy replacement without disassembling the hammer. Enhanced with carburizing treatment, it delivers excellent abrasion resistance.
4. Featuring patented bit designs, our hammers can drill holes of varying sizes simply by replacing the drill bit, ensuring sample integrity and preventing contamination.
5. Our hammers excel in challenging conditions such as loose soil, hard rock, and areas with abundant water, ensuring reliable and precise sampling.
