| High Light | Multi-Purpose DTH Hammer Bits ，QL60 152mm High Air Pressure ，Mining Water Well Geothermal Bits | ||
The ROSCHEN QL60 152mm Multi-Purpose DTH Button Bit is engineered for drilling contractors who demand one reliable bit across multiple job site conditions. Whether you are drilling mining blast holes, water wells, geothermal boreholes or construction pile foundations, this versatile bit delivers consistent performance without requiring bit changes.
| Application | Typical Depth | Performance Feature |
|---|---|---|
| Mining Blast Holes | 15-40m | High penetration rate in hard abrasive rock, minimal hole deviation |
| Water Well Drilling | 50-300m | Efficient flushing through layered formations, consistent diameter |
| Geothermal Boreholes | 100-500m | Heat-stable carbide inserts retain hardness at elevated downhole temperatures |
| Construction Piling | 10-30m | Durable gauge protection through mixed overburden and bedrock |
In granite quarry testing, QL60 152mm bits achieved average penetration rates of 0.8-1.2 m/min with bit life exceeding 500 meters in hard rock conditions. In water well applications through alternating sand, clay and limestone layers, consistent 152mm borehole diameter was maintained throughout the full bit service life.
