Description
Keentool supply series good quality Chinese low pressure Down-The-Hole Hammer of CIR-90, CIR-80, CIR-65, KQ-65, KQ-80, KQ-90, and high pressure DTH hammer of COP32 and COP34, as well as hammer bit with diameters of 65mm, 76mm, 80mm and 90mm for the above hammer.
Down-The-Hole Drill Machines commonly used for drilling use a pneumatic system: The energy thrust is transmitted by compressed air. In fact Down-The-Hole Drill Machines need air compressors. The pneumatic hammers penetrate the rock mass by means of a drill rod that is nothing more than a shaped steel rod. The pneumatic system is supported or sometimes substituted by the hydraulic system in which hydraulic oil instead of air is used to transmit the energy.
