Faithfull Heavy Duty Tungsten Carbide Tipped Masonry Drill Bit 12mm 400mm

About this tool

The 12mm x 400mm Faithfull masonry drill bit delivers maximum reach combined with a substantial diameter, designed for the most demanding deep drilling applications in masonry construction. This exceptional length and diameter combination is essential for specialist structural work, installing long anchor systems and drilling through thick walls where both hole size and depth are critical. Ideal for professional contractors working on renovation projects, commercial installations and heavy-duty fixing requirements, 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 minimise flexing during deep drilling in the larger diameter, which is vital for accuracy and safety. The fast spiral flute design ensures continuous waste removal, maintaining drilling efficiency even at full depth. Manufactured to DIN 8039 standards with a zinc plated finish, it's designed for use in chucks up to 13mm capacity with impact or percussion drills.
