I'm not willing to drag out this whole tools thing.
But I was wondering what sort of Power Drill (Mains Operated) is the most common in the Electrical Industry, where you come from.
Also, how many of you guys have a Hammer Drill, as opposed to a Non-Hammer Drill, where a Hammer Drill is not really required?.
Over here, with our brick buildings, a hammer drill certainly comes in handy.
We as a rule use the Metabo(German) Brand drills, they last forever, provided that they are looked after.
The one I use, has a 13mm chuck(key-type) and has a Hammer setting on it.
