Robust one-piece hard metal plate drills through reinforcing iron with lasting performance and constant precision 4x90° geometry with specially developed equally high cutting edges and stable shoulders ensure precise, dimensionally accurate holes for professional anchor setting and secure dowel fastenings. Short spiral runs ensure rapid removal of drilling dust Radially shaped reinforcement protection: prevents snagging when hitting reinforcement and increases service life Wear marks: for assessing whether the tool is still suitable for drilling holes suitable for dowels 4-spiral drill body for pleasantly quiet drilling with low vibrations and optimal guidance in the drill hole The 4x4 design allows precise concentricity and minimizes wear and friction losses. This results in high and very consistent drilling performance over the entire service life with maximum efficiency
