If you’re looking for a hardware-free way to hang picture frames or plaques on the wall, you need a keyhole router bit. Set up is simple, and results are great.When I make a picture frame or plaque, my preference for providing a way to hang it on the wall is to use a keyhole router bit. I like the fact that I don’t need to go shopping for hanger hardware, and the slot provided by the keyhole bit allows the item to hang right against the wall, not stand off by the thickness of the hardware.
Router Table Set Up. Use a V-bit, not the keyhole cutter, to set up your router table.Measure from the point of the V-bit to the fence to locate the keyhole slot. I typically place the slot 1-1/4″, on center, from the edge. Lock the fence in position.
The Keyhole Bit. Install the keyhole bit in the router table and set the height of the bit. Don’t move the fence. For 3/4″ stock I set the height of the bit to 1/4″ from the table to the shoulder of the cutter. Set it lower for thinner material.
