- ✅ Civil/industrial water wells, irrigation wells
- ✅ Geothermal well, geothermal heat pump hole
- ✅ Deep hole mining, slope anchoring, geological exploration
- ✅ Mountainous areas, hills, no electricity/explosion-proof conditions
- ✅ Fast drilling speed in hard rock (30m/h level), strong deep hole capability
- ✅ Track/vehicle chassis, fast off-road/transition
- ✅ No electricity operation, explosion-proof, adaptable to harsh environments
- ⚠️ Need to be equipped with a high-power air compressor with high noise/dust levels
