YATO Burghiu pentru piatră 22 x 210/150 mm patru tăișuri SDS-Plus

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 holesóholes than with a standard drill
• the drill retains its diameter even after multiple holes have been drilled, allowing easy insertion of dowelsóanchors 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 dimensionalós standards for SDS+
