Odex Air Rotary Drilling

Main Content

Advantageous in unconsolidated formations with a high risk of caving

ODEX is an adaptation of the air-operated down-the-hole hammer. It uses a swing-out eccentric bit to ream the bottom of the casing.

Cuttings blow up through the drive sub and casing annulus to a swivel conducting them to a sample collector or onto the ground.

  • Rapid removal of cuttings
  • No use of drilling mud
  • High penetration rate, especially in resistant rock formation (e.g. basalt)
  • Easy soil and groundwater sampling during drilling
  • Possible to measure yield estimate at a selected depth in the formation
