Jan 18 2008World's Largest Drill Bit Is Pretty Big, I Guess

The world's largest drill bit was put to use last month boring a subway tunnel in Leipzig, Germany. This is it. As you can see it's relatively large. Not huge, but pretty big. For a drill bit. Now if it was a Reuben sandwich, that would be impressive. And filling. Can you imagine the amount of sauerkraut required for a sandwich that big? I'm thinking several cans at least. I'm also thinking about making one. Who's with me? You bring the ingredients, and I'll bring an appetite and my "kiss the cook but don't touch the buns" apron.

A close up picture of the bit after the jump.

FAKE!

It's not fake you jackass! They use drills that size for tunnel making all the time.

Didn't they use this beastie to dig the Chunnel as well?

I'm sorry for that outburst. It was totally uncalled for. You see, I have a very small penis, and sometimes it just makes me so angry that I just lose it. I'm such an asshole.

Awesome, its like the movie Total Recall!

REAL!!!

Ok, now that that was said...While watching the Discovery Channel, I saw these things...I don't know how much bigger this one is than the one I saw on there (they look about the same size, save maybe an inch or so). Point is, um, well I've seen them before, but for those of you who haven't, they're cool, large, and expensive.

@6 - now that was a funny post

#2, #1 had it coming.

#1, you think they use a shovel for this shit?!

This is like the weapon a maniacal James Bond villain would use to hold the world hostage. Pretty cool, though.

its like Krang's fucking drill from Teenage Mutant Ninja Turtles

BENNYYYYY!!! AHGETCHOOOO!!!!

I'd like to know the feed rate of that drill.

Uh the largest one is drilling a water tunnel near Niagara Falls right now I think.

Correct me if I am wrong, it would probabally drill 2 inches a minute wouldnt it?
