Reliable HY20 Rock Drill Equipment

The HY20 rock drill is a high-efficiency, wide-adaptability equipment for medium-to-high hardness rock drilling, with core advantages focusing on "enhanced impact performance + stable large-flow power support". Its **rock hardness adaptation range of F=6-20** covers most industrial rock scenarios—from soft shallow mine rocks (F=6) to hard deep tunnel strata (F=20), eliminating the need for frequent equipment replacement when facing different rock types and improving on-site operation flexibility. Its structural parameters are optimized for stronger drilling capabilities. The 52mm piston stroke (1mm longer than small models) and 64mm cylinder diameter (6mm larger than small models) form a high-impact combination: the longer stroke enhances the drill bit’s penetration force, while the larger cylinder diameter increases air intake volume, effectively improving rock-breaking efficiency. In medium-hard rock (F=12-15) scenarios, it can shorten single-hole drilling time by 20%-25% compared to…
