Strong impact energy
High penetration efficiency
Excellent hard rock drilling ability
Effective drilling debris removal
Stable deep-hole drilling performance

This technology is especially suitable for:

Granite formations
Limestone layers
Rocky soil
Hard rock conditions
Geological investigation projects

By transferring impact energy directly to the bottom of the borehole, the HQZ-220L improves drilling efficiency and reduces energy loss.
