I’m guessing a key hole bit.

My dad's birthday is coming up, and he and my mom bought a lake house this year that they're still getting just right. I thought I could make a key rack (largely based on Jay Bates's design) for the doorway. The major deviation from Jay's design is that I routed keyhole slots on the back for hanging instead of having unsightly (imo) screws visible from the front.

Here's a link to Jay's key holder video if you're interested.

This is the router bit that I used to make the keyhole slots on the back (sorry, forgot to get images uploaded of those). Worked very well with a plunge router, and I think it looks way nicer that way.

How do you figure? I regularly make keyholes in stock less than 1/2" thick with one of these.
