Review on 🔧 Bosch CO2148 4 5 Cobalt Drill: Unleash Exceptional Power and Precision by Jay Campbell

I used this drill bit to drill a hole in my exhaust manifold and after watching a few YouTube videos I was hooked on the task at hand. Put this bit on my drill press, take some WD40, cut slowly and spray WD40 along the way. This bit lasted no more than 1 minute before severing the old exhaust manifold. I just bought another one of a different size to remove a broken steering damper. I won't buy anything else for a Steel Aver! GREAT BIT saves you a lot of work!
