Core Drill

"You're looking at the blazing heart of Muspelheim. Beyond that shield is what you seek - the Forge! ...And the portal home to Asgard." "I will find a way through the shield." "You will if you look UP. The drill..."

- Loki and Thor

The Muspelheim Drill was used by the Frost Giants of Muspelheim to forge Scabrite.

History
Thor used Mjølnir to shatter the anchors that were holding the drill up. He then made his way onto the drill and fought his way in, eventually coming across an Infernir Champion. Upon defeating the Champion, he used the drill to break open the barrier to the Infernal Forge, then destroyed the drill from within.
