These rods are used to enable overlaying the edges of cavities or holes. The holes are plugged with the graphite rod which is allowed to protrude from the edge of the hole. The overlay can then be applied around the rod, without any of it reducing the diameter of the opening. The graphite plug is then destroyed.
