These IRWIN Multi-Material Extended-Length Drill Bits can drill through just about any type of material, including brick, block, tile, metal, wood, plastic and marble and they can even drill through multiple materials at the same time. These versatile drill bits are designed specifically for rotary drilling but are tough enough to be used with hammer drills. The carbide tip has a diamond-ground, 4-facet design with sharp cutting edges for centered starts with virtually no walking and fast drilling in a variety of materials.
