I am gearing up to drill my 90gal AGA tank for a closed loop, however, I need help! Can someone please give me advice???
I am fairly confident in what I need to do to drill the glass. I have acquired the diamond hole saws from AmeriGlass. I have duly read the old thread back on RC, and know how to set up a dam out of modeling clay to keep the drill bits and glass bathed in water during the drilling process. Finally, I have read the maximum drilling speed information on the AmeriGlass web site. For hole saws of my size (1.5" and 1.75" for 0.75" and 1" bulkheads), a speed between 150 and 300rpm is recommended, being closer to 150rpm.
However...
I have one lingering question I cannot resolve on my own: how do I go about drilling the holes? More specifically, what type of power drill would I use to generate a specific speed? I went to Home Depot (first mistake) and asked them if they carry a power drill where you can set the maximum speed. They claimed to have no such drill. I have a power drill with the traditional trigger, but I am afraid to use it, as I have no idea what speed I am generating, and fear that while holding it in place for the n minutes it will take to drill through the 3/8" thick glass, the speed may increase to a dangerous level, and once I crack the glass, it is all over. I noticed that Home Depot did have a few cordless drills for sale where the maximum speed wasn't much greater than a few hundred rpm, but still, how would I make sure I'm not drilling over the 150 to 300rpm speed? Its hard to look at a rotating drill bit and tell. Therefore, I ask: what type of power drill did you use to drill your glass?
