The keyhole bit and the Dremel plunge router attachment make it easy to create "keyholes" for hanging shelves, brackets, picture frames and more.
Set the depth of the 655 keyhole router bit in the plunge router attachment. Test the depth on a scrap piece of wood.
To begin making a hole in the shelf, plunge the router down into the wood. Recommended speed: 35.000 rpm.
After the plunge cut, guide the bit across the wood approximately 1" to create the slot.
Repeat steps 2 and 3 to make the second keyhole. Now you are ready to hang the shelf and display your favorite item.
