CIR Hammer is a new product combining the advantages of DHD Hammer and QCZ Hammer. The wind pressure of working is between 0.5-0.7MPa.
The CIR Hammer with advanced technology has high quality and quick speed of drilling. CIR hammer has bigger specific energy of shock and lower power consumption while operating. The momentum transfer reaches the ideal level.
Advantage:
1. Deliver maximum energy to drilling bit, fast drilling speed and low air consumption
2. Smooth performance and long service life
3. Low problem rate and easy to maintenance
4. Easy to depart bit from hammer
5. Interchangeable with DTH bit and drill pipe
Packing: DTH hammer and bits will be package with cartons or with wooden case
