Atlas Copco COP 1838HD+ Flushing Head 3115 5044 00 / 3115 5044 05 | Rock Drill Spare Parts

Precision-Engineered Flushing Head for Maximum Drilling Reliability

Part No. 3115 5044 00 / 3115 5044 05 is a critical OEM-spec flushing head for the Atlas Copco COP 1838HD+ hydraulic rock drill. Installed in the front head assembly, it delivers controlled air or water into the drill hole to evacuate cuttings, prevent blockage, reduce overheating, and significantly extend bit and drill tool life.

Manufactured from high-strength alloy steel and subjected to strict dimensional and functional validation, this part offers direct interchangeability with original equipment — no modifications required. Ideal for demanding underground mining, tunneling jumbo rigs, and quarry operations where uptime and reliability are non-negotiable.

Key Advantages

  • Direct OEM-spec replacement — exact fit, zero retrofitting needed
  • Optimized for dual-media flushing (air or water) to maximize debris removal
  • High-strength alloy steel construction resists wear in abrasive mining environments
  • Proven to reduce drill hole blockage and thermal stress on tools
  • Precision-machined to ±0.02 mm tolerances for consistent performance
  • Cost-effective alternative with full compatibility and documented quality traceability

Applications

  • Underground hard-rock mining drilling
  • Tunnel boring and jumbo rig applications
  • Quarry and open-pit rock drilling operations
  • Hydraulic rock drill systems requiring high-integrity flushing
  • Retrofit and maintenance programs for aging COP 1838HD+ fleets
  • Epiroc-compatible drilling platforms (post-merger part lineage)
