I have the Fien as I enjoy their multitool for not shaking my teeth out.
I have however not been very impressed or happy with the drill.
I find the chuck is very hard to put bits in correctly. The slightest tiniest bit off and the drill bit (Fisch Pro's) wobble all over the place. You get better at it but it's still not great. I actually returned a few Fisch bits thinking they were bent but soon realised it was the chuck on the Fein.
The amount of movement between the attached heads and the body is quite a lot so when you have a heavier bit on, it seems to wobble at the end, even when inserted correctly in the chuck.
I also find the hex adapter to not really grab on to hex shanks that well. Perhaps it could be a bit deeper? They feel it's a bit losey goosy and have the accordingly wobbling tip.
I was expecting better and I have to send it in under warranty repair because introduced to the slightest bit of plaster dust, the forward and reverse switch has become incredibly stiff and makes a very nasty, plastic on plastic scraping noise, when being toggled.
If I had to buy another drill would I buy the same one?
Hmm well it fits my hand like a glove, it's nice and light and it stands to attention when you're talking to it. Very big positives.
The chuck and over-all fragility of the model though, is disappointing.
Oh and the right angle attachment head is £80 and £30 on the mafell and almost all other brands.
Come on Fein, have a word with yourself. Customer loyalty should be rewarded not taken advantage of.
