Advantage
1.Valve air distribution. More reliable.
2.Simple design of the piston, long life.
3.More efficient energy transfer, faster drilling speed
Performance characteristics of the impactor of the down-the-hole drill:
1. The internal structure and size of the impactor are designed using the contemporary new rock drilling theory,
2.The unique taper diameter reduction design, if gravel and soil are stuck during drilling, the taper diameter reduction can reduce the lifting resistance when the drill rig is lifted, and greatly reduce the occurrence of failures that the impactor cannot be lifted.
