1. Ring bit and casing shoe assembly is welded to casing prior to drilling. Lock the assembly into pilot bit with DTH (Down the Hole) or top hammer. The upper shoulder of pilot bit engages the shoulder of casing shoe.
2. DTH or Top Hammer's percussive energy is transferred through the pilot and ring bits, crushing rock. Some part of impact energy advances casing.
3. On completion of drilling and casing, the drill string with pilot bit is retrieved by a slight reverse rotation to unlock the bayonet coupling. The ring bit stays in the hole, and can also be recovered only if the casing is retrieved.
4. Drilling continues to the desired depth in the bedrock using a conventional drilling.
