I have had this version for many years obviously since I think it was a 2007 version. In all this time, it has seen very very use as i don't have the need to travel outside my shop with my tools like I did when I first got into Festool. I need to check, but I think I may have used a couple of the drill bits a few times but not enough to wear them out. The only I seem to gravitate to is the countersink bit. I am trying to guage if this kit would be highly desired or not? If so, I may opt to sell it.
