If you want to hang a picture and have the frame be flat against the wall and be perfectly level, this is what you need. A router table is helpful in getting two keyhole cuts identical and, therefore, the frame perfectly level.

The shortness didn’t effect performance, however I did use the router bit in a milling machine. I expect it would be just fine in a router as well (I will use it in my router most of the time). I have my router setup to do another job I’m working on hence the use in my mill.

I create a lot of wood wall hanging art and this Keyhole bit works great and is the perfect size for the standard drywall screwheads. For a couple quick jobs, I was even able to forgo the router and make the cuts on my drill press.
