4.5inch RE542 High Efficiency RC Drill Hammer for Water Well Drilling and Mining

• Button bit features high wear resistance for medium-hard to hard abrasive rock formations (200-260 Mpa compressive strength)
• Spherical tungsten carbide inserts provide strong configuration against carbide fracture
• Effectively eliminates hole deviation
• Ideal for drifting and tunneling applications
• Optimized bit face design for medium-hard to hard abrasive rock

RC (Reverse Circulation) drilling utilizes Dual Wall or Dual Tube Drilling technology. Compressed air flows down the annulus of the rod into the hammer and bit. Rock fragments crushed by the bit are collected into the inner tube via air holes on the bit head, then returned to the surface for sampling.

Applications include:

• Underground mining and quarries
• Hydraulic and Hydro-Power Engineering
• Water well drilling and mineral exploration
• Anchoring hole drilling and geothermal engineering
• Subway excavation and civil engineering projects
