Used to improve drilling small holes in a metal insulating cup. The mug absorbed water into the heat-insulating layer every time it was washed, and the water did not flow out. I couldn't drill through the metal with conventional drill bits. With these titanium drill bits I was able to easily drill a small hole to allow air in on one side and water out on the other.
