One thing to consider is that both brands and practices vary a lot=20
between countries. I don't think i've ever seen a drill in the UK that=20
looks like the one you have pictured or for that matter come across the=20
Milwakee brand.

I get the impression (from my own experiances in the UK and from=20
watching TV shows in the US) that we use a lot more masonary and a lot=20
less timber here in the UK than americans do. So most moderately big=20
drills over here will be hammer drills, you can put a holesaw in one and=20
drill a big hole in wood if you need to but that isn't their primary=20
design goal. Dunno what it's like in the rest of the world.

Another thing that has already been mentioned is that in the UK=20
proffesional power tools are usualy 110V (though 240V versions are also=20
available). Construction site regs in the UK forbid or at least strongly=20
discourage use of 240V power supplies for tools and most proffesionals=20
spend at least some of their time on construction sites.
