i need to drill two 1.25" holes in the top of my case (internal) in order to mount a 2x120mm in the roof. the material is what looks like about 1mm thick stainless steel. the holes will be placed on the black "t" marks. i went out and bought an inch and a quarter mandrel at the hardware store (pictured) but after talking to my friend who is an electrician, im not sure if this is the best tool for the job. hes taking a look for a better bit tomorrow. cant take the chance of tearing up the case. i plan on using the rubber gaskets that came with the case to the tubing will be protected. any suggestions?
