The 12mm x 300mm Faithfull masonry drill bit combines a substantial diameter with extended reach, making it ideal for heavy-duty installations requiring deep penetration through thick masonry sections. This specification is particularly valuable for structural fixing work, through-wall installations and applications demanding both size and depth. Designed for professional trades including builders, electricians and plumbers working on substantial projects, this bit features a heavy-duty tungsten carbide tip that maintains cutting efficiency even when drilling deep holes in tough masonry materials. The roll formed and treated body provides the necessary rigidity to prevent flexing during extended drilling operations, whilst the fast spiral design ensures continuous debris removal from the larger diameter bore. Manufactured to DIN 8039 standards with a zinc plated finish, it's suitable for use in chucks up to 13mm capacity with impact or percussion drills.
