I built a wooden boat and drilled hundreds of holes with this drill. Now I've built a second small boat using the same tool. By my count I've drilled a few thousand holes with this bit. Now he's dead. The tip is broken and one of the hex set screws has snapped off. I'll buy the same beat again because I feel it did a good job. I haven't been kind to it in normal use and have dropped it on the concrete floor more times than I can count.
