The Drill Bit

I got this guy for just about 25 bucks at the local Lowes there were a few sizes to choose from but they are all really well labeled on the packages and on the drill itself. So I placed the bit into the unit I was drilling the hole for and then taped off the next size up so I knew where to stop. After I drilled in the first way, I flipped my drill over and drilled in gently from the other side to remove any burrs and slag.

For a drill I just use a basic old two speed ryobi 18v battery powered drill.
