Specially designed to access places with small clearance, where with another drill you cannot do the job.
The machine is very sturdy and feels very well in difficult situations.
I have this as a second battery operated drill/screwdriver, and in situations were you have to drill first a whole and than apply a screw, it makes life much easier.
Also it is much more ergonomic to apply pressure while drilling.
The drill is designed to fit a 18V Lithium battery, an 18V NiMH fits as well but looks a bit awkward.
Do not forget, the battery is not included and an original DeWalt battery is more expensive than the drill.
All in all I am very happy with this marvelous piece of hardware.
