This is a serious drill.
(Ed — it’s an auger, surely?)
Now that’s going to make a pretty deep hole, by anyone’s standards.
So what happens if you drill too far? What comes out?

To prove it does actually go as deep as you think, here’s it just before it gets to the bottom.
Not a lot of drill-bit left.
It’s quite a cool machine. First it drills the hole, then the concrete factory on the far end of that hose starts up:
The hose is connected to the top of the drill-bit (Ed – “auger”, I keep telling you!) which is hollow. As the bit is screwed back out the ground, the concrete is pumped out the bottom end of the bit, filling the hole with concrete.
To polish it off, there are 2 sets of rotating brushes in front of the cab that scrub all the mud off the bit as it comes out. Nice clean drill bit! (Ed — “auger”, FFS!)
*An extremely small chance, much less than 1 in the-number-of-people-who-enter. But a chance, nonetheless.
P.S. Now you can’t un-see that photo either. Don’t blame me, blame Twitter. If it’s going to be stuck in my head forever, it’s going to be stuck in yours too.
