Today, I was working alongside a bloke who had a Festool drill / driver. I have never seen them in the flesh before, and was rather sceptical of their value, being as they are roughly 3 times the price of a 'normal' drill from Bosch/Makita et al.
Anyway, my view has totally changed. They are truly excellent. They come with 3 differing chucks,and a driver chuck. These chucks are changed in less than 10 seconds, they are eccentric chuck, std. chuck, angled chuck, and the driver head chuck. The head ensures all drilling/driving is self centring. In use they are very smooth, and apparently, the 12v version is as good as other makes 18v drills.
The only downside is that I have to find £350 to buy one now. Alan.
