3.On completion of drilling and casing, the drill string wit pilot bit is retrieved by a slight reverse rotation to unlock the bayonet coupling. The ring bit stays in the hole, and can be recovered only if the casing is retrieved.
4. If further drilling is required on the bedrock, the pilot bit is simply replaced by an appropriate size of standard DTH bit.
