An electric drill has a small electric motor inside, driving a series of gears. The power from the gears turn a chuck, which holds the bit placed into it thereby drilling a hole.

An SDS hammer drill is an electric drill that hammers the drill bit in and out slightly as it drills with it. This type of drill is mainly used to make holes in concrete or masonry, and is able to do so easier than a regular drill and bit are.
If you have the drill in your hand with the chuck away from you, if the rotation goes clockwise it is going forward and if it is counterclockwise it is going in reverse.
