It doesn't have a name right now.
"The newest machine in the power miners arsenal, this drilling rig is mainly for drilling out heavier rock, thus the carbide drill. It is also renowned for its speed in the tunnels, leading to races between hotshot miners."
Sort of a $15-$20 set equivalent.
And Tekka's Tunnel bike was built to accompany this drilling machine.
Edit: Got it up on Brickshelf(when modded), but MOCpages is being difficult
Edit again: What color does the background look to you?
