What to Look for on a Pro Level Drill

No tool is more iconic of work around the jobsite or the home than a drill. If there’s work to be done, somewhere along the line it likely requires a hole made (drill), a fastener driven (drill), or a screw removed (drill). If only the ancient Egyptians or Romans, who used drills of some fashion, could see how technology has improved upon their concepts. We don’t even have to go back that far in history. Our own grandfathers used hand drills with a crank mechanism or simply a T-handle and some elbow grease. Since then, manufacturers have electrified drills with cords and then untethered them with lithium-ion batteries. Fortunately, we get the benefit of those innovations that make jobs easier and give us more control. But what to look for on a Pro level drill is different than what the DIYer needs.

Generally speaking, this is a good list to go by for the construction industry. However, electricians have different needs than general contractors. So if you’re new to your trade, start here, but ask around to see what the other Pros you work with carry.


What to Look for on a Pro Level Drill


Regular readers will be familiar with our article on the contrast between brushed and brushless motors which we link to quite often. Brushed motors are physically commutated, which means inside the motor there’s contact between brushes and the commutator. This creates friction, heat, and wear on the brushes that will eventually need replacement. Brushless motors are electronically commutated. This eliminates that wear and tear and results in longer motor life. But that’s not all; brushless motors allow smart electronics – that is, communication between the motor and battery that maximizes performance and protects against damaging thermal overload. Companies like Milwaukee Tool have innovated around these smart electronics to create even more impressive functionality like Milwaukee One-Key – an app-based tool control and fleet management technology. Brushless motors are also lighter but – as you may have suspected with all these advantages – more expensive.

Pro Pick: A brushless motor is best, but there are still some solid options with brushed motors

Size and Power

Technology often creates format wars that, in retrospect, result in oddball product offerings. Eventually, the consumers and manufacturers settle on some sort of standard – think VHS and Betamax or Blu-Ray vs HD-DVD. There’s a hint of that in lithium-ion nominal voltages that manufacturers have offered in 6, 9.6, 14.4 and other assorted levels over the years. But by-and-large, you’ll find 12V and 18V cordless tools now. DeWalt, in what might have been a stroke of genius, confused the marketplace for a while with its 20V Max line of tools, but these are the same as 18V tools.

Generally, the size of the chuck moves higher with the battery’s voltage (and price!). You’ve likely seen drills advertised as a 3/8-inch or a 1/2-inch. This refers to the chuck size or the bits shank diameter that the drill will accept. More often than not, you’ll see 3/8-inch 12Vs and 1/2-inch 18Vs.

So do you need a 12V platform or an 18V platform? Good question! We wrestled with that question in depth here. Unless you’re in production work, chances are you can perform 80 – 90% of your job – and tasks around the house – with a 12V tool. They are lighter, charge faster (at least for now), smaller, and less expensive. But you’ll still run into the tough or stubborn job that requires 18V muscle.

Pro Pick: Start with a 1/2“, 18V drill and supplement with a 3/8”, 12V when your budget allows.

Speed and Control

Although some smaller or less expensive drills have just one speed, many drills have a low and high RPM switch – 1 and 2 – on top. RPM range from around 300 to a couple thousand. Lower speed has higher torque and higher speed has lower torque. The choice, of course, depends on the material being drilled or fastener being used. Two speeds will suffice for most users. You’ll find a few drills with three speeds. And then once in a great while, you’ll run across a 4-speeder like this Hilti which provided the utmost control for nuanced work. But even our diminutive 12V, single speed Ryobi has a variable speed trigger (as do our bigger 18V tools) so there’s more variability and control than first meets the eye.

Pro Pick: At least 2 speeds and 1800 RPM

But how much torque do you really need? Some drills go as high as 1200 in. lbs. and some are in the low 300’s. There are several classes from 12V to 18V compact and 18V heavy-duty. Generally speaking, as you move up that line you get more torque along with increased size.

Pro Pick: For heavy-duty drills, get at least 750 in. lbs. of torque. If you can only afford one drill at the moment, it’ll tackle most of your applications without an issue. 

Have you ever rounded out the head of a screw when the driver bit you were using left its seat and caused damage? Or have you ever driven a screw below the material’s surface when you just wanted it flush? Even better: has the screw head ever snapped off during the drive? If so, you have first-hand experience with excessive torque. It ain’t pretty. You want just enough torque to complete the task without doing any damage. Those numbers that encircle a drill’s chuck are clutch adjustments that modulate torque. The lower the number, the lower the torque. For fine work or soft (cheap) fasteners that easily deform, low torque is best. For denser materials that the bit will need to dig deep to bore into, high torque works best.

Pro Pick: Make sure you get a drill with clutch settings.

Torque-y Behavior

Now, in a discussion about torque, we’d be remiss if we didn’t mention a standout safety feature in some of Hilti’s most powerful drills: Active Torque Control, or ATC. It works in two ways. First, it protects the user’s hands, elbows, shoulders in a bind-up situation where the bit stops and the drill wrenches violently. Second, it stops the drill’s motor even if it has slowly moved about 135° from its starting point. We’re sure Hilti, known for its excellent yet expensive tools, has this feature locked up, but we’re hoping more manufacturers find a way to accomplish the same thing. Be on the lookout for torque control mechanisms as you shop for drills.

Pro Pick: ATC is great on heavy-duty drills, but it’s not common in the industry yet. This one is optional… at the moment.

Other Feature Considerations

Some features have become standard and we might not even need to point them out – but we will anyway! Keyless chucks are one of those things. Although being able to tighten a drill or driver bit into the chuck simply by putting the drill in forward, holding the chuck, and pulling the trigger is convenient, we’re a little sad that young people today will never have the joy of searching for a chuck key or getting some skin caught in the chuck and key gears. However, chucks still come in both plastic and metal. Plastic chucks seem to hold as tight as the metal ones, although they mar more easily when they rub against objects in tight spaces. All metal chucks are part of tougher tools, though.

Pro Pick: Look for a keyless metal chuck.

A work light is also almost standard. It can make a world of difference to have a flashlight each time you pull the trigger. We’ve also used them to find small screws we’ve dropped in the dark or to illuminate our toolboxes when they might not be organized well enough!

Pro Pick: Your drill needs an LED light. The ones that surround the chuck are the best. 

A hammer function can come in handy for masonry work. If you anticipate drilling into block, brick, or stone, consider a drill with a hammer function. Hammer drills use a different mechanism than masonry-focused rotary hammers, but for occasional, light-duty masonry drilling, the hammer drill is just fine. You might even consider an auxiliary t-handle to give you stability and control. This is a premium feature that will bump up the price, though.

Pro Pick: Hammering function is optional for the Pro. Masonry drilling is best left to a rotary hammer, but a hammer drill can be handy in occasional light-duty applications. 

We like drills that have rubberized overmold in the areas that touch the ground when the tool’s laying down. These “bumpers” will protect the tool body plastic and extend its life. Make sure it has a comfortable, secure feeling in the hand. We particularly like Ridgid’s Hex Grip.

Pro Pick: Your drill needs a rubber overmold on the handle for security and around vulnerable parts of the drill in case you drop it. 


We hope this helps you have a better idea of what to look for on a Pro level drill. Like just about any other product, there are some entry-level features you’ll want at entry level prices, but you should also consider the premium features even if it means spending a little more. Keep in mind that you won’t make your drill decision in a vacuum. Adopting a battery platform is a little like getting married – you get the whole family, too!
