    So far, so good, must follow instructions
  

*by A***N on Reviewed in the United States 🇺🇸 on July 6, 2023*

I used the one inch bit to drill holes on the bottom of a thick glazed pot. It worked fine. You must keep water flowing while you drill, and start the hole on a 45 degree angle till it bites in, then ease it over straight down and move it a little back and forth while drilling. These are way cheaper than ones I saw in the home stores.
