Behold, the Hitachi DH50MRY. Part drill, part jackhammer, it can eat up concrete like balsa wood without killing your arms. Our friends at PopSci cut one open to show how it works.

It's the first drill of its kind to feature a counterweight strong enough to cancel out what is undoubtedly some pretty serious recoil. I still think it would take all the counterweight in the world for this not to shake my spaghetti arms out of their sockets in two, maybe three seconds. But that picture—can't take my eyes off it.
