When buying a cordless drill and cordless impact drill, you might want to consider the following:

A cordless drill is the most important power tool you'll buy. It's the one you can rely on for big projects like building a deck and remodeling a kitchen, as well as smaller tasks like installing fixtures and assembling furniture.

Most cordless drills in use today are powered by lithium-ion (li-ion) batteries, which offer more power and longer runtime in a lighter package than before. According to the Natural Resources Defense Council, lithium-ion batteries have improved so much in the past decade that a newer cordless drill can run 50 percent longer than a cordless drill from seven years ago.

Many modern cordless drills also benefit from a motor redesign. Until recently, brushless motors (as opposed to the more common brushed cordless drills) were reserved for niche brands like DeWalt, Makita, and Milwaukee, but they are now available in modestly priced consumer drills.

Unlike brushed motors, which run at the same speed whether you're drilling softwood (like pine) or hardwood (like oak) - draining the battery - brushless motors adapt to the resistance they encounter and use less energy. They also operate with less friction than brushed motors, allowing them to work more efficiently. They also have fewer moving parts and, because there are no brushes, you never have to think about replacing them.

Cordless impact drills are extremely powerful and compact tools that drive screws into wood, metal and cement more efficiently than traditional cordless drills, making them a popular choice for tough jobs like building a deck or home improvement.
