De Coster Dominique on a jobsite in Hasselt with a Fundex F2200. The machine is equipped for drilling screw-shaped piles with an Olivier drill auger head d36/56. Here they use the patented system where no lost bit is needed. This is a considerable cost saving per pile! With this system, the auger can be positioned much more precisely. Because there is no longer a need to place a lost bit by hand under the auger, there is no more risk of accidents.
