Key Advantages
  • Ultra Accurate Drilling Trajectory : Φ39 / 45mm chisel pilot ensures straight drilling path, creating smooth hole walls without step deviation for precise reaming operations.
  • Fast Reaming Speed : Upgraded staggered ballistic carbide button tooth layout disperses impact force evenly, reducing single meter reaming time by nearly 20%.
  • Durable Construction : High strength alloy steel with full vacuum quenching and tempering treatment eliminates internal stress, adapting to harsh mining environments.
  • Easy Maintenance : Quick disassembly with standard drill rod extractor - no special tools required.
Applications
  • Underground metal mine and coal mine blasting relief hole drilling
  • Highway and railway tunnel excavation and anchor cable holes
  • Open pit quarry stone mining and large diameter blasting holes
  • Water conservancy dam slope anchoring projects
  • Municipal foundation pit rock breaking engineering
  • Gas drainage hole construction in coal mines
