Top 10 Best "Cordless Screwdriver"

A versatile, compact choice for fastening or drilling in wood, plastic, and even some light metals, the DeWalt DW920K-2 Heavy Duty Cordless Screwdriver Provides 0-500 RPM and 80 in./lbs. of torque for fast, efficient performance. Featuring a unique two-position handle that lets you choose to use the driver in-line or with a pistol-style grip, this tool offers a variety of convenient features for intuitive use. Variable speed capability, a conveniently place reversing trigger, and an electric brake combine to offer great results, while a quick-release, industrial hex-shank chuck secures bits in place with minimal slippage. The hinge at the heart of the two-position handle is crafted from metal for increased durability, and it offers a locking-mechanism, so you can work confidently. Also included in the kit are a one-hour charger, two 7.2-volt compact batteries, two screwdriver bits, and a heavy-duty kit box for storage and transport. This DeWalt high-performance industrial tool is backed by a 3-year limited warranty.

Tired of that battery-powered screwdriver being dead when you need it most? Here's an alternative. Surprisingly powerful and stunningly lightweight, Black & Decker's 3.6-Volt Cordless Screwdriver features the best energy-to-weight ratio and longest-lasting charge available. Just the right weight and style for assembling furniture, hanging curtains, and mounting light fixtures, this tool is powered by a lithium-ion battery that holds a charge up to 18 months longer than comparable nickel-cadmium-powered drivers.

A very forgiving power screwdriver for those who hate cords but frequently forget to recharge, the lithium-ion battery also helps this tool deliver 20 percent more power than Ni-Cad tools. When it is time for a recharge, a fixed, internal battery lets you just drop the whole tool into the included charging base, rather than detaching it from the tool and attaching it to the charger, a process that sometimes takes longer than driving the darn screw. Half the size of most screwdrivers in its class, this tool is great for working in tight quarters and around tough corners.

Powerful and durable enough for years of household use, the tool's pistol grip makes overhead driving a much more comfortable task than you'll experience with in-line drivers that require an uncomfortably bent elbow that shortens reach. And, at just 2.6 pounds, there's no more dying strain to finish extended overhead driving tasks. Not that there'll be such a thing as extended applications. This driver spins screws at 180 rotations per minute and churns out 48-inch pounds of torque, easily rivaling most drill/drivers pound for pound, and definitely providing a welcome rest for the wrist. Best of all, Black and Decker's Grab-N-Go charger mounts to walls for easy access. The purchase is covered by a 2-year manufacturer warranty. --Brian Olson
