Just as cellular technology freed the telephone, the advent of lithium-ion batteries forever altered the landscape of power tools. While the electric drill was always a homeowner favorite, its cordless version has become truly ubiquitous, appearing in the toolboxes of even casual do-it-yourselfers. If you own any power tools whatsoever, chances are you have a cordless drill. The popularity of these drills has led to a wealth of models on the market. With so many to choose from, how can you be sure to pick the best cordless drill for your needs? Keep these factors in mind as you navigate the selection process.
Voltage.Cordless drills range from 7.2-volt models to ones boasting 20 volts or more. The most popular options are 12 and 18 volts; that's plenty of power for most light-duty household tasks. Higher voltage equals faster drilling and screw-driving, but while speed can be a virtue, extreme speed is beneficial mainly to professionals. 12- and 18-volt drills are fast enough without becoming difficult to handle.
Weight. Over the years, cordless drills have gotten only lighter. It's not unreasonable to focus your search on tools that come in under five pounds. But weight isn't the only determinant of comfort. Equally important is the tool's balance. To test the balance of a drill you're considering, grip the handle firmly in your dominant hand, then lift it toward the wall as if you were going to drive a screw. The drill chuck should point straight at the wall without your having to fight to keep it from tilting up or down.
Battery Type. Older cordless drills run on nickel-cadmium (NiCd) or nickel-metal hydride (NiMH) batteries. Today's best cordless drills, however, run on lithium-ion batteries. These weigh less, last longer, and recharge more quickly than their predecessors. The only downside to note is that for all their advantages, lithium-ion batteries are pricey to replace, running as much as $100 or more.
Accessories. Different cordless drill packages come with different features and accessories. Depending on how you intend to use the tool, one or another of the following features may be worth pursuing:
- extra battery
- "smart" battery charger (capable of recharging in 15 to 60 minutes)
- battery-charge indicator
- variable speeds
- built-in work light and/or level
- warranty for drill and battery
