Transformers: Prime Edit
Energon Drillers were at work in one of the Decepticons' Energon mines which Starscream showed to Megatron. When the Autobots attacked the mine in an attempt to recover Cliffjumper, several miners tried to use their Energon Drillers to fend them off, but were easily tossed aside. The machines were presumably destroyed when Starscream then blew up the mine.
Three Energon Drillers were stored inside a supposedly stripped energon mine that Starscream was using for himself. After Arcee and Megatron brought the mine down in a gunfight, Jack Darby commandeered an Energon Driller to rescue Miko and Bulkhead.
Later, Knock Out and some miners used a drill to uncover an Iacon relic in New York's subway system.
