Hello!
I happened to receive this Bosch 49pcs Drill Set recently for (+) Enclosures Quiz - Documents - Industrial Automation - element14 Community. That's of course a great brand and the kit items looked interesting. So, to give it a try, I ordered GBM 350 Drill | Bosch Professional (bosch-pt.co.in) drilling machine. Not a hy-end one, but well enough for my home use. I tried varieties of bits and drilled on wood, metal and concrete wall. Using it as a screw driver is also a cool thing and the machine's controllable speed offered this capability(although I couldn't use it the best).
Here's a review video on items in the kit and some of the mistakes I made as a noob who randomly happened to pick up a drilling machine 
Thanks to E14 and the Sponsor for putting up such a great quiz covering knowledge about the Enclosures and Cases, its Standards(which I never knew about), and for this great prize. Indeed a great toolkit and comes to be super handy. Enjoyed working around it!
