pressure gas flush off with an aim that keep the hole’s bottom clean.The durable piston on the

 

hardness treatment can have two end changed ,which can extend the working life .

 

2.Designed a changeable vapour lock,which can change the gas charge according to rocks

 

hardness and abrasion resistance to realize the best flash effect and highest drilling effciency.

 

3.Simple structure and few but wearable spare parts make longer working time.

 

4.Front joint adding with a multiply heads thread makes the disassembly much easier.
