Select a battery with more amp hours (Ah) for a longer run time. Batteries typically run from 2 up to 6 Ah. The tradeoff for more run time is weight. Get a full-size tool over a smaller, lighter model to do heavier work. A full-size drill has a larger motor and a more stout drive gear assembly. A subcompact drill has a smaller motor and smaller drive gear assembly but is more nimble. Thus, it’s less tiring when it comes to small repetitive jobs, like hanging window hardware, where you’re likely to be holding the tool above your head.

We marked off knots in our test lumber by drawing across the board with a square and a carpenter’s pencil and then scribbled out the areas to be sure we didn’t drill into them. When we saw how readily the Ridgid could make a hole, we didn’t really feel the need to steer clear of knots. The Ridgid made a hole, knot or no. We were particularly impressed by how easily it cleared the bottom of the hole.

To be clear, we call this a stubborn drill lovingly. The ONE+ HP 18V is a competent maker of holes and driver of screws. It’s fairly easy for a drill to make a one-inch-diameter hole through ¾-inch thick white pine. But at the bottom of a 1.5-inch-deep hole in Douglas fir, just before the bit punches through, that’s where the trouble starts. That’s why we use that test, frankly. Many drills will stall there. The Ryobi did, too.

It should be obvious that this drill is not petite. Although the drill is the same size as a large 18-volt drill, it is heavier than most of its competitors. With the 2.5-Ah battery, it weighs 5.2 pounds.

The cordless drill is indispensable for maintenance and repair jobs around the house and on your car or for working on gear from bikes to skis to your barbecue grill. It drills holes in wood and metal and drives screws into either material with equal enthusiasm. When equipped with a hammer option, it can even make holes in concrete, brick, and mortar. The tool’s importance and versatility are why we’re constantly testing for the best cordless drills.

Flex, short for Flex Elektrowerkzeuge, is a German power tool company muscling its way into the American market. And when we say “muscling in,” we’re not kidding. We’ve tried a batch of these tools (drills, saws, rotary hammers and grinders) and find them to be formidable competitors in the professional segment. The FX1171T blasted out its hole allotment, helped by its turbo mode setting that bumps up the top speed from 2,000 to 2,500 rpm.

The GPH01D is the first tool we’ve tried in Makita’s new 40-volt XGT series, power tools with 40-volt motors but batteries that are the same size as a large 18-volt. Fortunately, the tool has great control because all that power would be useless without being able to handle it properly. Its trigger response is superb. Balancing that with its electronic speed control that maintains motor speed under load put us in the driver seat (okay, we’ll stop here with the sports car analogies). That’s helpful drilling wood, but even more important drilling steel, where it’s far more difficult to balance the variables of motor speed, bit diameter, and steel hardness and thickness.

If you plan to drill into masonry (brick, concrete, mortar, stone, pavers), you need a drill with a hammer option. This mechanism imparts a percussion action to the bit as it rotates, helping a carbide-tip masonry bit to chip away material as it turns.

The DCD805 was the only drill in this test that ran so cool that we pushed it right to the end without any sign of thermal stress. It just went merrily about its business of blasting one hole after another, and when it was done, it was done. It didn’t even feel warm. We put it aside thinking that even if it didn’t feel cool, we’d give it a rest. Nope, it was dead.

A CNC Milling Machine differs from CNC Routers in the design. CNC Mills are designed to have rigid or semi-rigid Z-X gantries, and a dynamic moving base/workpiece.

It may not be the monstrous hole-drilling terror that the Flexvolt is (probably the most powerful cordless drill we’ve ever used), but it’s lighter and somewhat smaller than that drill. Even with the hefty 5-Ah battery we installed on it (the drill is sold bare), it weighs a relatively modest 4.2 pounds, about average or slightly less than a full-size drill. Mind you, this drill has a hammer function at that weight. Many less capable drills weigh that without the hammer function. That ability enlarges the drill’s spectrum to making holes in masonry.

We were very pleasantly surprised by the Hart’s punch-above-its-price hole-making performance. While it didn’t drill as many holes as other tools, it made each one quickly and cleanly, indicating decent torque and a solid drivetrain. You get a sense of this right at the bottom of the hole, when the bit encounters maximum wood-on-metal resistance. It still needs enough torque to break through while maintaining rpm to throw the chips out of the top of the hole. The Hart did this for each of its 40 holes. Other features that provide good value are its a hammer setting for masonry hole drilling and a sturdy side handle that bolts right through the tool body. We found the handle didn’t loosen no matter how hard we pushed the drill.

Also helping was the tool’s circuitry, which has an anti-kickback feature. We can’t fully vouch for that particular feature, but we can say that we pushed this Flex very hard and noticed no kick back; the drill will pause momentarily if you really lean into it (call it a reset). You should know that this is clearly a heavy-duty tool intended for people who need maximum power and run time.

This Makita’s engineering is masterful in other ways. Instead of a clutch ring, like a normal drill, it has electronic drive torque control. Turn a knob just above its battery to set the torque limit of the clutch to disengage the drivetrain and motor. The absence of a manual clutch ring at the front of the drill simplifies set up for drilling, driving, or hammer drilling. Three large icons (a hammer, a screw, and a drill bit) are easy to see, and this helps to quickly adjust the drill to the appropriate setting.

The FX1171T, with a 5-Ah battery, was the heaviest of the drills (5.8 pounds). The other large-battery tools were the DeWalt (5.4 pounds) and the Makita (5.2 pounds), and these were also pro-duty, intended for either serious do-it-yourselfers or contractors. But as to the tool’s weight, we don’t count that as a mark against it. If you need this much power tool muscle you just need to have some muscle of your own.

Our marathon champion by a wide margin is this DeWalt. Combine a highly powerful motor with a hefty 6-Ah battery and you get outsized performance. And very efficient performance, too; the big yellow drill managed more than 50 holes per Ah. The Flexvolt features king-size torque, speed, and a lack of vibration even under severe load. Its excellent trigger response allows you to fine-tune drilling speed and breakout at the bottom of the hole or reverse the bit and back out. The three-setting speed selector also enables this. If there’s wood, metal, or masonry and you need to put a hole in it (or lots of holes in it), this is an excellent choice.

The good news is that it also has a strong headedness that allows it to persevere, hole after hole. It kept going and didn’t shut off due to thermal overload. In the end, that feature and a 4-Ah battery helped the tool rack up a lot of holes. We consider anything over 100 holes in this test to deserve a rating of somewhere in the pro to prosumer range of power tools. If it makes that number easily, it’s a pro tool. If it labors, it’s prosumer. There are many other features to like on the Ryobi, such as a sturdy side handle, a comfortable grip, good balance, and a lack of vibration as it goes about its work.

Designed to be desktop or cupboard mounted machines, these milling machines have the significant size advantage over router machines which generally require a large bench space.

To evaluate each tool, we made 25 holes through Douglas fir 2 x 8 (Grade: “No. 2 and Better”) using a sharp 1-inch-wide Speedbor spade bit—the classic design without a lead screw. Next, we drove 25 lag screws. Each screw was ¼ inch in diameter and 2 inches long. Then we backed each screw out. After that, we went back to drilling holes with the spade bit until the tool’s thermal overload circuit prevented drilling. After letting the battery and the drill cool off for 15 minutes, we continued drilling until the battery died or the drill could only make its holes with difficulty. During this test, we drilled 2,070 holes and drove 525 lag screws.

This is a tough test. It takes lots of torque to send a 1-inch-wide spade bit through Douglas fir framing lumber, particularly breaking out the wood at the bottom of the hole where there is maximum friction. As rigorous as this test is, we were pleasantly surprised by some homeowner-grade models that turned in spunky performances. That is to say, you may long to buy professional-duty equipment, but there’s no sense in buying more drill than you need.

The most common cordless drills are in the 18- to 20-volt range. These are well suited to carpentry, deck building, and remodeling jobs. Select a smaller 12-volt drill for minor repairs, basic woodworking, and light carpentry. These are also easier to handle for jobs like assembling flat-pack furniture, putting together sporting equipment, and the assembly and disassembly work that goes along with repairing appliances. With these jobs, the emphasis is on screw driving and not on hole drilling.

We live in an era where “made in America” tends to be more the exception than the rule. So it was a distinct pleasure to open the Craftsman box and slide out a neatly sewn tool bag bearing an American-made drill driver with two batteries and a charger. It was even more pleasant to use the tool. It churned through 48 holes. That’s 24 holes per amp hour of battery capacity, a respectable efficiency. Its lightweight, high torque, comfortable control surfaces such as its handle, switches and chuck, and its hole-drilling performance all combine to make this not only a good buy in the power tool market, but a power tool worthy to identify itself as made here.

This drill is part of Worx’s Nitro power tools, a line of equipment to which we’ve given high marks. Like the smaller Ryobi above, this drill also had a problem with the one-inch spade bit test in Douglas fir. That’s not surprising. But this is a likable power tool because it’s light and reasonably powerful for its size. We think it’s likely a good fit for furniture assembly, small repairs, and installation jobs like hanging closet rods and blinds. We actually like the fact that it lacks a hammer mechanism, which keeps its weight down. It’s unlikely you would need a hammer function in this class of product, and many homeowners don’t need it anyway. If you want a heavier drill with hammer action, Worx makes a Nitro version of that, too.

The fastest in this test was the Makita. Using this drill, you feel like somebody just tossed you the keys to their Ferrari. Pull its trigger (floor it, if you will), and you just burn through one hole after another until the battery is done. So long as you keep that trigger pulled, it will just churn through hole after hole. Knots don’t stop it and barely slow it down. It’s almost ridiculously fast. Okay, it didn’t bore the most holes in this test, but it did get to its number faster than anything else.

Some cordless drills come with a side handle that you can attach and remove as needed. If you plan a heavy construction project with the tool, such as boring large or deep holes through house or deck framing, this side handle will help you steady the drill with less fatigue and more control, particularly should the tool bind in and kick back.

Look at the specs and package. Does the drill come by itself, without a battery and a charger, or does it come with one or two batteries, a charger, and maybe a carrying case? For a little more money, some drills have a rapid charger that quickly replenishes the battery to partial charge in minutes. This can help you finish a project a little quicker than you might be able to otherwise.

Generally speaking, that’s where most drills run into trouble. The combination of friction and the build up of wood chips can bog down the best of drills. No problem for the Ridgid. It sailed through the bottom of the hole, the center, and the top. Its lag driving is equally good, and when we set the speed selector switch to 1 (low speed, high torque), it backed out the most stubbornly driven lag screws without a hint of difficulty.
