Vault Dalek
From TARDIS Index File, the free Doctor Who reference.
The Vault Daleks were Daleks charged with guarding Davros in the vault of the Crucible.
[edit] Information
Each Vault Dalek or Crucible Dalek was created from a single cell of Davros' body and kept within the vault to watch him by order of the Supreme Dalek.
They were fitted with a special type of manipulator arm, with a claw possessing eight pincers which could operate machinery. The Vault Daleks were destroyed when the Crucible exploded. (DW: The Stolen Earth/Journey's End)
[edit] Behind the Scenes
Vault Daleks were not named during The Stolen Earth/Journey's End, but are referred to as such on the official BBC website.
They have also become known as 'Crucible Daleks', primarily due to the toy manufacturer Character Options naming the variant in this manner as part of its range of Doctor Who 5 inch action figures.
