Bosch Daredevil Drill Bits
These hex-shank bits drill all sort of materials, from aluminum to masonry.
With a strong resemblance to standard masonry bits, these impact-rated bits promise to get through most materials. The manufacturer claims that you can drill through brick, concrete block, tile, cementitious tile backer, wood, PVC, and aluminum. Testing reveals the bit does great on masonry, but drills slowly through wood and aluminum. A set like the one shown, with bits sized from 5/32-in. to 3/8-in., sells for about $20.
