Low Pressure DTH Hammer

 Low Pressure DTH Hammer

Features
1. The low pressure DTH hammer from Superman is a valved central exhaust drill tool which ensures a perfect effect of blowing clear rock flakes and dust. This reduces the repeated crushing of rock flakes, thus lowering wear of drilling bits and improving drilling efficiency.

2. Based on the up to date rock drilling design principle, the DTH drilling equipment features the most reasonable internal structure and size which enable ideal energy transmission, with large single impact energy, high efficiency and less air consumption.

3. Thanks to the highest quality raw materials and state of the art processing technology, our low pressure DTH hammer comes with more stable performance and higher longevity. In addition, the mining tool provides simple structure, easy installation and disassembly, low failure rate and convenient maintenance.
