Robust single-piece 4-edge tungsten carbide head for extreme durability and low-vibration drilling. Precision cutting facets deliver accurately sized holes, optimizing anchor fitting. Patented chamfered tip enhances fracture resistance, ideal for drilling into reinforced concrete. Self-centering tip minimizes bit wander for precise hole placement. Four-flute design facilitates efficient dust removal and maintains a strong core to prevent bending and breakage. Suitable for use on concrete, high MPA concrete, hard aggregate, masonry, hard stone, and brick. Note: X-Bits larger than 12mm feature a conventional three-piece carbide head. Available all range for deeper drilling requirements.
