Using our keyhole router bits is the best way to secure any wall hanging object by nail or screw, eliminating inconvenient and unsightly wires and hooks. The advantage to this mounting method is that the picture, plaque or other object being hung will sit snug to your wall and perfectly straight.
First, the bit plunge cuts an entry hole. Then, as the router moves forward, it cuts a narrow slot with a wider slot beneath the surface. This creates a shoulder to securely grab screw or nail heads.
Bit 50-504 is two flute, the others are single flute.
We also have T-slot router bits for making custom wall hanging units.
