Drills, power tools and more can cut down on the time you spend working and give you more time to relax. Drills can bore holes in some of the toughest materials known to man or it can quickly put a screw in place when it's used in place of a regular screwdriver.
You can find these tools in either electric or battery charged. Most people prefer the battery charged due to the convenience of being able to use the drill anywhere they need to.

The downside of course, is if you forget to charge the tool before a job, you can run out of juice and you'll be stuck waiting for the recharge. Not only are they good for driving in screws but in removing them as well by their reverse action.
The drill bits will vary in size and the drill itself can range in size from lightweight to fairly heavy. Try out the drill you're thinking of buying before you take it home so that you'll get the one that won't strain your hand and wrist.
Depending on what you plan to use the tool for, look for the longest lasting battery life that you can find. Drills, power tools and more are meant to make life easier, not harder but choosing the wrong model can not only be a waste of time and money but can leave you frustrated as well when it fails to perform as you expect it should.
