Working Principles:
  1. When drilling, the reamer swings out and drills a hole larger than the external diameter of the casing tube.
  2. When the required depth has been reached, the drill is reversed and the reamer swings in to its minimum diameter, allowing the bit to be lifted up through the casing, which is left in the hole.
  3. Drilling can continue with an ordinary DTH drill bit.
