Reverse Circulation hammer (RC hammer) is our most advanced product, used in deep hole exploration drilling and mining ore grade control, etc.
Characteristic:
- Reference the design and production experience of conventional DTH hammer and combine the operating characteristics of RC hammer; internal structure design is optimized to ensure ideal energy transfer and high drilling speed as well as steady sampling.
- Simple internal structure and rigid components ensure long using life and easy maintenance of the hammer.
- Sample tube is integrative designed and can be placed without disassembling of the hammer. With carburizing treatment, the sample tube has good wear resistance.
- RC bit has patented design. One hammer could drill different size of holes just by replacing different size bits, and ensure no contamination of the sample as well.
- In difficult conditions such as loose soil, hard rock formation or plenty of water exists, sampling can be done well.
