Inverted Core Drilling

We had to Core Drill Inverted (upside Down) in Walgett Police Station in the prison cells. This work had to be done using Hydraulic Drill motors as this was not able to be done with electric motors as there would have been a possibility of electric shock. The work had to be done from below as there was a lack of room in the roof cavity. Other work done at the Walgett Police Station, in Northwest NSW was Concrete Cutting, Hand Sawing and Core Drilling.
