This is a cordless electric drill/driver kit.
From the photo, the case contains:
Cordless drill/driver — suitable for drilling and driving screws.
Rechargeable battery — fitted to the drill.
Battery charger — plugs into mains power.
Multiple screwdriver bits — Phillips, flat and other types.
Drill bits — several sizes for drilling holes.
Socket adapters/bits — useful for nuts and bolts.
Wall plugs/anchors — for fixing items to masonry/walls.
Bit holder/extension — helps reach screws in deeper areas.
The drill also appears to have an adjustable torque clutch, forward/reverse control, and variable-speed trigger.
