Review on 🔩 CO Z Titanium Automatic Aluminum Multiple: Cutting-Edge Efficiency and Durability Combined by Michael Lucas

Product descriptions and pictures are deceiving. These beats are not good at all. I had to drill 3 holes in a new stainless steel sink. The drill was fine until it was reduced to 7/8, after which it immediately dulled. After that, he just rolled and smoked without much progress. I almost burned the motor in my drill press. After 30 minutes of drilling I finally got through 1 1/8 which was just what I needed. Incidentally, the smaller bit also became blunt after 3 rings. Yes, I used machine oil to lubricate the bits. To make the other two holes I had to go to the hardware store and buy another drill bit.
