Faithfull Standard Masonry Drill Bit 8 x 400mm FAIS8400

The 8mm x 400mm Faithfull masonry drill bit represents maximum reach in this popular 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 extremely thick cavity walls, historic stonework and commercial-grade masonry, all whilst maintaining the versatile 8mm fixing diameter. Ideal for professional builders working on substantial renovation projects, installing long cable and service runs, accessing areas where conventional bits cannot reach, and specialist construction requiring both popular diameter and maximum penetration, 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 exceptional rigidity to prevent dangerous flexing during deep drilling operations over this considerable distance. The fast spiral flute design ensures continuous debris removal, which is critical for maintaining drilling speed and reducing bit wear at such depths. Designed for use in chucks up to 13mm capacity with impact or percussion drills, this specialist bit offers maximum versatility and reach.
