Slide Block Casing Drilling System

description

When driling in unstable ground overburden. Drils the hole and drives the casing at the same time ensuring the hole does not collapse. Saves time as casing is run at the same time as the hole is drilled.

Advantages

1. Nothing left in the holes.

2. No reverse rotation needed! Bit wings retract inside the casing eliminating unscrewing problems.

3.Faster penetration rates- large bit face area for transferring blow energy.

4. Rapid penetration/minimum drilling time- bit used at full operating pressure of hammer.

5. Simultaneously drill and case - wings extend further than OD when bit reaches bottom.
