Dalek Cleaver

The Dalek Cleaver was a Dalek spacecraft-slash-weapon.

Nicknamed the "cosmic can opener" by Earth's space pilots, this spacecraft was one of the unique ships at the disposal fo the elite Dalek Task Force. It was capable of hurling itself as anything up to and including a mountain and then boring its way through with no speed loss. (NOTVALID: The Dalek Task Force)

Behind the scenes
Although not used in a narrative story, Big Finish used similar drill-ships for the cover of some of its Time War series including: Only the Monstrous, The Thousand Worlds and The Heart of the Battle.
