It mainly featured in:
1.The strong energy of single impact and the low energy consumption in rock crushing;
2.The weight ratio of Piston and Bit almost reaches 1:1 to provide long effective acting time,which leads to the improve efficiency om rock crushing and the extended service life of the drilling tool;
3.A good performance in central air exhaust and cuttings discharge,which reduces the repeated crushing of rock;
