A twist auger for boring holes 3.4cm in diameter. It comprises of a bit (the cutting part), on a shank which ends in a tang to fit into a wooden handle(separate). The screw lead at the tip of the bit pulls the auger through the hole, reducing the amount of pressure required. (Salaman Dictionary of Woodworking Tools)
