Premium series SDS-plus drill bit designed for reinforced concrete & in industrial applications Characteristics:• grinded surface, thanks to a lower friction coefficient, enables 50% more holesoholesthan with a standard drill• the drill retains its diameter even after drilling many holes, allowing easy insertion of dowelsoanchors and anchors into the hole• extremely hard 4-cut fork, equipped with additional cutting edges, drills rebar in reinforced concrete. /strong>• • the automated fork brazing process guarantees maximum heat resistance during serial drilling in reinforced concrete – in standard drills the widia falls off from the head of the drill when it encounters the rebar• deep spiral, preceded by 4 grooves in the drill head, effectively drains the excavated material• made of resilient high-carbon steel, resistant to deformation nbsp;to deformation caused by high impact force and frequency (does not lock in SDS holder)• centering process eliminates lateral runout• drill shank meets global dimensionaló standards for SDS+
