Slo-mo drill in action

Hat tip to the blog for pointing me at this video.

I'd guess you can work out what it shows as any reader of this blog is undoubtedly an erudite and well-educated individual, but in case anyone has accidentally ended up here looking for something else - Its a drill bit mounted in a lathe making a hole in a bit of metal. That's why the drill is still and the metal moves. An added bonus is it makes seeing what is going on a heck of a lot easier.

Maybe it's just me, but I find the point where the drill starts to work fascinating. The bits really cuts into the surface, a bit like a chisel, which is why it is shaped like it is. In fact, as you watch this, it it is obvious just how sophisticated the shape of a drill is to make a hold and clear away the swarf. Odd that we take them for granted as much as we do.
