I have a 12 v cordless drill model CXS from Festool. You can remove the chuck with one hand and put on the angle chuck attachment 360 deg.
Very handy.
I could never justify $250 for a drill though. A buddy who used to work for them gave it to me.
Now Festool makes some seriously fine tools. Expensive? Yep. Then again between the quality and the design features, well worth the money for those who depend on their tools for their livelihood.
Then again, they are made in Germany.
