I knew I could get a pretty poor quality drill with it for about $7, but I only had to drill 2 holes in a rock to install a hose hanger and I figured hey, even worse drills should be able to handle it. no The first bit made about 3/4 of the first hole and then fell apart inside the wall. He collapsed. The tip of the chisel got stuck in the hole and the rod crumbled. Luckily you get two small pieces so I agreed and switched to the second. Drilled about halfway through the 2nd hole and the chisel lost its entire hook. nothing left I need to buy a second set of bits to complete my project.
