The Best Cordless Drills By Jennifer Jafarzadeh

Best All-Around

Ryobi 12-Volt Cordless Drill/Driver Kit

Weight: 3.48 pounds.

What it comes with: A 26-piece accessories set, two batteries, a charger, a stud finder, and a plastic storage case. But it's what comes on this drill that makes it the best value: A built-in level lets you know your screw will go straight into the wall, and a small magnetic tray in the handle stores loose screws and bits, so you won't lose them or need to store them between your teeth as you work.

How it works: It's light enough not to tire your arm out on big projects, like installing a shelving system, yet it has staying power: It drove in more than 250 screws on one battery charge.

To buy: $81, amazon.com.
