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

Got these bits because I needed to drill some holes in the computer case for water cooling. The manufacturer said the body was aluminum so I figured these bits would work. Not even a hole was drilled in the case. I ended up using a dremel to finish the job. I will send these back as soon as possible.
