Benefits when comparing to conventional rock drills:

  • when idling (percussion on with the shank rod not at the impact point), stresses to tie bolts

  caused by piston damping are eliminated with the internal structure of the percussion

  cartridge

  • percussion piston designed for the best possible energy transfer for rock breaking
  • low feed force means low rotation resistance, higher durability of drilling tools
  • robust rotation gear structure
  • easy to maintain, less special tools needed

Drilling results from a construction site in February 2012:

  • hard grey granite, tensile strenght 250MPa, vertical holes
  • ballistic button bit, diameter 51mm
  • Drilling speed 1,2m/min feed pressure 30bar (mounted at ROC512HC)
  • Percussion pressure 140 bar rotation pressure 40bar
