How to choose

Start by deciding whether the added performance and ruggedness of a heavy-duty drill are worth its higher price and weight. Then keep these tips in mind:

Check the battery

Lithium-ion batteries deliver more speed and power per pound than nickel-cadmium (NiCd) cells. But several NiCd-powered tools came close in our tests for less money.

Look for time-savers

Our recommended models (available to subscribers) include a second battery that lets you keep working while the first one recharges. Multiple speed settings let you move from low speed for driving screws to high speed for drilling holes. A drill with a ½-inch chuck accepts larger bits than one with a ⅜-inch chuck.

Don't buy solely by voltage

Many of the best tools pack 18 volts. But the lower-voltage Panasonic drill and Makita impact driver still delivered top performance.

Try before buying

Hold the drill; its nose should point straight ahead without tipping up or down. Then raise it to be sure it isn't too heavy for overhead tasks.

Pass on cordless screwdrivers

They weigh 1 pound or less and fit inside a shirt pocket. But our tests have found even $100 models slow and short on power.
