YDH 210 Hydraulic Rock Drill 175 Bar

Precision-Built Hydraulic Rock Drill for Demanding Underground & Surface Applications

The YDH 210 hydraulic rock drill is engineered for high-efficiency rock penetration in mining, tunneling, and quarrying operations. Delivering robust 175 bar percussion pressure and 300 J impact energy, it supports versatile bit compatibility (T45, R38, T38, R32) and a wide 43–115 mm drilling diameter range. Its integrated high-strength spline sleeves, dual-mode (water/wind) slag discharge system, and 18 kW output ensure reliability under continuous heavy-duty use.

Key Advantages

  • 175 bar rated percussion oil pressure for consistent high-impact performance
  • 300 J impact energy with 2500–3700 bpm percussion frequency
  • Full compatibility with industry-standard T45, R38, T38, and R32 drill bits
  • Dual slag discharge: configurable for high-pressure water or compressed air
  • Heavy-duty construction with reinforced spline sleeves and 180 kg rugged frame
  • Optimized hydraulic efficiency: 80–100 L/min percussion flow & 30–44 L/min rotation flow

Applications

  • Underground hard-rock mining (stoping, development, raise boring)
  • Tunnel excavation and roadheader support drilling
  • Quarry face drilling and secondary fragmentation
  • Foundation piling and geotechnical exploration
  • Hydropower cavern and civil infrastructure drilling
  • Blast hole drilling in abrasive granite and basalt formations
