Mission series M30 M40 M50 M60 M80 DTH Hammer The main features of Mission Series DTH hammer: 

1.Better energy transduction, faster working speed and less air consumption. 

2.Best raw material with advanced production process. 

3.Stable working performance, long life and easier to use, assemble and repair. 

Applications: It is mainly used in Drilling and drilling blasting holes, landslide protection, anchoring holes, ground heat source air conditioning, hydrology, 

water well holes and other fields in mines, quarries, road construction and other projects.
