A machine for boring a tap hole of a shaft furnace is presented for use in conjunction with a lost-rod process. In this process, a metal rod is driven into a botting mass, before it has completely hardened, and is removed later for opening a tap hole. Driving-in of the rod is performed with the aid of a to-and-fro movement of a clamp which can move over a mount through action of a first jack. Removal is performed with the aid of a continuous reverse movement of the clamp through the action of the first jack and of a powerful drive means, for example a second jack, driving the first jack towards the rear of the mount.
