Using a Keyhole Bit

Using a Keyhole BitIf 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.

 

Using a Keyhole BitRouter 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.

Using a Keyhole BitUse a square to transfer the location of the center of the bit to the face of the fence.

Using a Keyhole BitThe 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.

    wouldn’t you want the key hole cut to be perpendicular to the item you’re hanging?

      If I’m understanding correctly to make the key hole perpendicular it should only have one hole for screw head entry

    I make the keyhole parallel to the top edge of whatever I’m hanging. Put the screw in the wall, engage the head on the back of your work, slide it left and right until it hangs straight, and you’re set.

    To easily lift the plaque off of the spinning bit at the end of the cut. I place a thin tape at the right side of the plaque. Then at the end of the cut, I can easily lift the plaque off the bit.

    George, the following makes no sense: “Stop when the right layout mark is aligned with the cutter center line. The left layout mark on the plaque should be on the cutter center line.” Both marks cannot be on the center line. You must star on the left and end on the right.

      Sorry, there’s an extra line of text there. The caption for that photo should simply be “The left layout mark on the plaque should be on the cutter center line.”
