Classic four-blade drill bit for reinforced concrete with a blade resistant to damage upon contact with rebar. Use for drilling in reinforced concrete, silicate, ceramic brick.
The double helix prevents the drill bit from jamming when discharging a large amount of excavated material. The steel of the drill body is resistant to temperature expansion, so the drill does not lock in the chuck.
