I use "Low Voltage Mounting Bracket (1 Group x 5), Fosmon Low Voltage Mounting Bracket (Mounting Screws Included) for Phone Cable, Network Cable, HDMI Cable, Coaxial Cable, Speaker Cable" with brackets this tool. Once the hole is cut the brackets just don't fit and I have to cut the hole on both sides. I'm not sure why they don't match, but I'm surprised they don't. At least I have a guide that makes even holes and a square to begin with. I could do it easily enough, but whatever.
