While cordless drills win in the “most portable” category, they can’t compete with corded drills when it comes to power, speed, and the ability to keep on working as long as you want to without stopping for a battery recharge.
We spent hours researching corded drills from the most popular tool brands, evaluating power, reliability, and versatility. Our favorite corded drill is the BLACK+DECKER DR260C 3/8-Inch Corded Drill, thanks to its compact size, variable speeds, and powerful performance.
Here are the best corded drills for all of your DIY needs.
The BLACK+DECKER DR260C Corded Drill (available at Amazon) wins our top spot by virtue of its versatility, power, and light weight. If, however, you need a tool with enough power to easily drill right through steel, you’ll find that the DEWALT Variable Speed Drill (available at Amazon) is up to the task and then some.
The big advantage to choosing a corded drill over a cordless model is power. Corded drills, which run from your home or worksite’s 110-volt electrical supply, rather than a battery as with cordless drills, have plenty of nonstop muscle to get the job done.
Amps measure the power of a corded drill’s motor. Most of today’s corded drills have motors that fall between 5 amps and 10 amps, with the higher number being more powerful. That’s important, because the stronger the motor, the more torque—that’s the force with which the drill bit rotates—the tool possesses. Still, don’t automatically assume that you need the most powerful drill; for general around-the-house tasks, a 5-amp to 7-amp motor is usually sufficient. But if you routinely drill through hard materials, such as masonry or metals, you’ll find a higher-power drill is better suited to your needs.
The chuck is the clamp at the front of the drill that holds the bit in place. When purchasing drill bits, you need to select bits the same size or smaller than your drill’s chuck.
The three most common chuck sizes are:
- ¼-inch, which is a light-duty drill
- 3/8-inch, which is a general-purpose drill
- ½-inch, which is a heavy-duty drill
You’ll also want to consider the ease of switching out drill bits.
- Keyed chucks require a “key” tool to switch bits.
- Keyless chucks, which are by far the most common today, let you switch the bit without a tool. Often, you just twist and tighten the bit with your hand.
Rotation speed refers to how many full revolutions the bit makes per minute (rpm.) As a general rule, corded drills have maximum rotation speeds of 200 rpm to 2,000 rpm. For typical DIY tasks around the house, 500 to 1,000 rpm is sufficient. Don’t assume that the faster the drill, the more powerful it is—that’s not necessarily true, as it’s the amount of torque, not speed, that determines how well a drill penetrates hard materials.
Many lower-end drills have just one maximum speed, but higher-end drills often have variable-speed settings, letting you choose from two or more speeds. Usually, lower speeds are best for drilling into harder materials, while faster speeds are suited to softer materials.
Yes, you can swap drill bits between your corded and cordless drills as long as the two drills have the same chuck size; the chuck is the clamp at the front of your drill that holds the bit in place. To fit, a drill bit needs a shank that’s the same size or smaller than the drill’s chuck. As a general rule, a ⅜-inch chuck is a general purpose drill, a ¼-inch chuck is a light-duty drill, and a ½-inch chuck is a heavy-duty tool.
You certainly can use your corded drill as an electric screwdriver, just as long as you choose a screw-driving bit that matches the size and style of the screws you are turning; for example, you’ll need a Philip’s head bit for Philip’s head screws. When using your drill as a screwdriver, keep the speed and torque on the lowest settings to avoid stripping the screw.
The answer depends on how you treat the drill, as well as its quality. But as a general rule, a good-quality corded drill that’s treated right—not used for tasks beyond its capabilities, left out in wet or extreme weather conditions, or otherwise abused—can last for years or even decades.
