Faithfull Heavy Duty Tungsten Carbide Tipped Masonry Drill Bit 10mm 400mm

The 10mm x 400mm Faithfull masonry drill bit represents the maximum reach option in this diameter, designed for the most demanding deep drilling applications through substantial masonry structures. This exceptional length is essential for specialist tasks such as drilling through thick cavity walls, historic stonework and commercial-grade masonry installations. Perfect for professional builders working on renovation projects, installing long anchor systems and accessing areas where conventional bits cannot reach, this bit features a heavy-duty tungsten carbide tip engineered to maintain cutting performance throughout its extended length. The roll formed and treated body provides crucial rigidity to prevent dangerous flexing during deep drilling operations. The fast spiral flute design ensures continuous debris removal, which is critical for maintaining drilling speed and reducing bit wear at such depths. Manufactured to DIN 8039 standards with a zinc plated finish, it's suitable for us
