Review on 🔩 Shank Glass Tile Drill by OCGIG by Eric Pruett

They have been very useful to me. I drilled glass about an inch thick to create a drainage hole in the candle jar, which I converted into a planter. They drill drainage holes in ceramic/clay pots flawlessly! Also, I'm glad they came with some general instructions on how to use it (add water, etc.) because they were helpful.
