Hardened carbide steel construction with unique point grinding for fast, accurate drilling. Quickly drills through wood, plastics, brick, concrete, tiles, marble and steel with the same bit. The high efficiency of these bits means that they are not suitable for use with hammer action, instead the simple drilling function of a combi drill or drill driver is ideal.
