A solid core plug formed from wood, plastic, or a composite woody material of substantially cylindrical shape with a body portion and an integral tapered forward portion. The outer face of the body portion has a diameter substantially equal to the inside diameter of the core for which the core plug is intended, and the inner face of the forward portion is of slightly less diameter than the outer face to facilitate entry of the core plug into the ends of a core. The core plug includes an opening or groove spaced from the center thereof and near its remote outer edge which extends the full length thereof for facilitating removal of the core plug from a core.
