CMT 850.501.11 Solid Carbide Keyhole Bit, 1/2-Inch Shank, 3/8-Inch Diameter
This CMT keyhole bit lets you make holes for keeping your frames, plaques or any wall hanging perfectly straight and attached to the wall. The bit bores an entry hole in the wood, then proceeds to cut a 3/16-Inch hole and finishes by boring a larger opening under the surface. The perfect way to securely mount wall hangings on screws and nails.
