The Inside Of An Electric Drill

The chuck on my drill failed.  So I thought, why I don't take the cover off the drill to find what it looked like inside.  And this is what I found.  

Quite an assortment of components.

Whilst food shopping, I came across this drill in Aldi's supermarket.  It was only £19.99 so I thought I'd give it a shot.  It has some features the broken drill didn't have.
