With CMT's keyhole bits you can make holes that keep your frames; plaques or an wall hanging perfectly straight and attached to the wall. The bit bores an entry hole in the wood; then cuts a 4.8mm hole and finishes by boring a larger opening under the surface. The perfect way to securely mount wall hangings on screws and nails.
