The concrete drills we offer are for installing concrete screws with a diameter of 6.3mm and 7.5mm. They have a specially designed body (flute) and two cutting edges, which allows quick removal of the dust from the hole and faster drilling.

For old and reduced-strength concrete, drill bits are used as follows: for a screw with a diameter of 6.3 mm, a drill bit with a diameter of 5.0 mm, for a screw with a diameter of 7.5 mm, a drill bit with a diameter of 6.0 mm.

For new concrete or concrete with increased strength, drill bits with a diameter of 5.5 mm and 6.5 mm should be used.
