Introducing our elite selection of RC Hammers Bits and DTH Hammer Bit Reverse Circulation Rock Drill Tools, each meticulously engineered to deliver unrivaled drilling efficiency and unmatched durability.
Our DTH Drill Bits are crafted from the finest nickel-alloy steel, significantly enhancing their resilience and wear resistance. Adhering to stringent heat treatment standards and employing specialized 'stress relief' processes, we guarantee each bit consistently delivers exceptional performance.
Our DTH hammer bits are meticulously designed to deliver peak performance and optimal hole characteristics, setting a new industry benchmark for drilling efficiency.
1. Leveraging our extensive experience with traditional hammers and integrating advanced features of reverse circulation hammers, we have meticulously optimized the internal structure to ensure fast, smooth, and continuous sampling with proficient energy transfer.
2. The hammer's internal structure is ingeniously simplified with high-rigidity components, ensuring extended lifespan and ease of maintenance.
3. The collection tube boasts an integrated design for seamless replacement without hammer disassembly. Enhanced with carburizing treatment, it offers outstanding abrasion resistance.
4. Our hammers are equipped with patented bits that allow for versatile drilling simply by replacing the bit, enabling the same hammer to drill various hole sizes while maintaining sample purity.
5. Even under challenging conditions such as loose soil, hard rock, or water-rich environments, our tools ensure efficient and reliable sampling.
