A recent topic from Kiriakos
http://www.ittsb.eu/forum/index.php?topic=708.msg1793#msg1793, gave me the idea to create this topic, relative with power-electric tools.
So lets start from my tools.
Back in 1995 when I was beginning to make my first steps in outdoor works (TV antenna installations) and as I was already making DIY electronic projects (amplifiers, speakers,etc.) it was required for me to buy a simple electric impact drill, because until then I was borrowing my father's Black&Decker electric drill.
So after a short market search ( internet these years was something "alien" for a common people, also internet trading/market simply didn't exist) I choose BOSCH as an acclaimed brand and particular PSB 500R.
A 500W electric drill with impact capability, rear/ front rotation and variable speed 0-2600 rpm.
Also its chuck, supported drills with max diameter of 13mm.
I bought it from a specialized tool store in the center of Athens, for about 16000 DRH (46,9 EURO) without carrying case (disadvantage..).
I completed my purchase with a simple plastic case, a set of air drills, and several wall/concrete drills with short and also long lengths, in order to drill walls from side to side for cable passing. I equipped it also with an extension wire with male-female outlet plug.
After few years I bought some HSS drills and also some long HSS drills (20-30cm) in order to drill door/windows aluminum panels ,for passing alarm cables through them, as I had started to undertake alarm system installations too.
All of these years this tool was working fine, without any problem and it was really a worth purchase according its specifications and price. But my work requirements were getting bigger, and it was many cases that I had to drill concrete ,where PSB500 has difficulties there... A work partner has a rotary hammer drill and gave it to me to try it at a concrete drilling, and I really impressed. So the next aim had been set.
Recent at 2011, I finally decided to make the jump to professional series ,and bought the BOSCH GBH2-20 rotary hammer drill. I bought also some short BOSCH SDS drills, 3 long ones and an flat chisel.
It doesnt need to mention specifications etc, its easy for someone to find them now on internet.
I have only to mention that this tool gave me many solutions and my work became more efficient as concrete drilling is now a routine.
And as well the word "complete" in technical jobs doesn't exist, I am planning to buy a wireless Li-ion tool for light works ( drilling / screw driving) in places without AC outlet. My most possible choice is BOSCH GSR 1800 (professional series).
