Portable Miner

"We don’t want you to harm yourself mining for ore bare-handed"

- Caterina Parks's assistant Steve



The Small Drill is a placeholder name for a structure that mines materials for the player, specifically ore such as Iron Ore, seen in the E3 trailer

Speculation
This seems to be an early game alternative to the miner, appearing to dump ores onto the ground which the player must collect by hand.
