The ADTnS DBD RM4 diamond core bit is excellent for high-strength reinforced concrete.
It has a speed of 3-5 cm per linear meter and a service life of 3-4 m per linear meter. when drilling M400 concrete with a 1.6 kW machine.
When passing through the reinforcement, it is recommended to reduce the rotation speed and minimize the feed of the drill bit into the material to be processed.
The drill bit must be re-restored by soldering a new ring segment.
Available in diameters from 12 mm to 35 mm with total lengths from 150 mm to 320 mm.
