The Gold Duramax core bit is the ideal tool for drilling medium and large diameter holes, mounted on machines with 1”1/4 fitting, with at least 2000 watt power and with a water connector. It guarantees a much longer life and drilling speed, thanks to the patented Duramax® technology that doses and perfectly positions the diamond granules in the diamond segment, and the spiral in the body that facilitates the removal of debris from the hole, for a unique performance. To use every diameter to the highest performance, it is decisive to have a machine with the power output and rpm suited to that diameter.
