Review on 🛠️ CO Z Titanium Drilling Cutting Electrical Tool by Jared Tovar

Bought to make a hole in my brew pot for a ball valve. Before buying, I watched a video on how to do it. I drilled a pilot hole and started with a step drill to enlarge the hole with lubricating oil. The first two steps were easy, then no more. I put this on my powerful drill press which also has a very high speed. Not correct. The club heated up and the steel hardened. I had to sharpen the drill and widen the hole a bit with a regular nozzle to get rid of the hardened area. I slowed the drill down as much as I could and it was still spinning in the hole. Wow, it worked like a charm. Low speed and lubrication. I've only used it once so have no idea on strength or durability but the videos I watched said it should last a really long time if you keep it slow and oily.
