The Drill Head is an attachment for the Large Rover and/or the Crane. Once attached it can be used to mine Lithium, Titanium and Astronium deposits as well as excavating terrain at a faster rate than the Terrain Tool. The Drill Head requires no power to operate.
Drill heads are visually similar to the Terrain Tool, and as of the Excavation Update now have exhaust tubes and a virtual inventory of their own to prevent unfinished stacks from overflowing.
