I always find it amazing that people could design intricate machines like that.

I dunno. I've known some women that like to pounded and drilled like that.

Is that his invention, or an antique?

That's cool and all, but why does it exist?

The typical reason for drilling holes in rock is so that you can pack explosives deeper into the core of the rock, I would imagine...

Probably for fun. The method of drilling shown is how it was done for 100s of years. One guy holding the rod and turning it, the other with the sledge. Kinda neat to show a mechanized version of the same process.

This is a precursor to hammer and rotary drills. It could be used to drill holes in to stone, cement, concrete, and masonry walls to allow for plumbing and electrical pipes to be installed.

Also bombs as /u/DeadAgent says.
