Digs a 3×3 hole. Two versions: horizontal (tunnels) and vertical (shafts).
Head block: use an iron block for a normal drill, or a diamond block for a faster one. Only a diamond head can dig obsidian.
Any kind of planks works.
Digs a tunnel 3 wide and 3 tall, driving forward as it goes. It moves away from the furnace.
