Freud 25/64 in. D X 1-5/8 in. L Carbide Key Hole Router Bit

This clever bit is designed to hang pictures, plaques or even shelves with completely concealed fasteners. The large diameter end bores holes to allow nail or screw heads to enter the slot and the smaller diameter allows room for the shank of the nail or screw. Great for hard or soft wood or composites, using hand-held or table-mounted routers.
