Whiteside Keyhole Router Bits

Keyhole router bits are specialized cutting tools used in woodworking to create keyhole-shaped slots or recesses on the back of a workpiece. These slots are commonly used to hang or mount the workpiece securely on a wall or other vertical surface.

Keyhole router bits typically have a cylindrical or straight shank with a cutting edge at the bottom. The cutting edge is shaped like a keyhole, with a larger circular opening at the top and a narrower slot extending downward.
