Sansung company makes and supplies the finest and most efficient Down-the-Hole (DTH) hammers and bits for the mining, construction and water well industries.
Drill and blast engineers and water well contractors trust Sansung's DTH equipment because of the precision engineering and high standards of drilling efficiency built into each of our hammers and bits.
CIR series Low Air Pressure DTH Hammer
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. We can provide hardening Hammer according to your needs. CIR hammer has bigger specific energy of shock and lower power consumption while operating. The momentum transfer reaches the ideal level.
Currently the most popular model is CIR90 DTH Hammer which is rather popular for low air pressure drilling and widely used in Brazil, Spain, Argentina, Saudi Arabia, India, Chile, Paraguay, etc...
