IRWIN multi-material drill bits drill through just about any type of material out there- brick, block, tile, metal, wood, plastic and marble-they will even drill through multiple materials at the same time. These versatile bits are designed specifically for rotary drilling, but are tough enough to be used with hammer drills.
