When you're shopping for a cordless drill, one specification can quietly change the entire buying decision: the motor type.
You'll usually encounter two choices: brushed and brushless.
At first glance, the difference may not seem dramatic. Both motors spin a drill bit. Both can drive screws, drill holes, and handle everyday DIY projects. And both are available in popular cordless platforms, including 20V systems.
So why do brushless drills often cost more?
The answer comes down to how the motor transfers electrical energy into mechanical movement. A brushed motor uses physical brushes and a commutator, while a brushless motor uses electronic controls instead. DEWALT explains that eliminating the brushes reduces friction and wear, helping brushless motors operate more efficiently and with less maintenance.
But here's the more interesting question:
Is paying roughly 30% more for brushless actually worth it?
The answer depends less on the sticker price and more on how often you use the drill, the type of work you do, battery runtime requirements, and whether you're building a cordless tool collection for the long haul.
Brushed vs. Brushless: What's the Difference?
Let's start with the mechanical difference.
How a Brushed Motor Works
A traditional brushed motor uses carbon brushes and a commutator to deliver electrical current to the motor's rotating components.
The brushes physically contact the commutator while the motor operates.
That design is proven, relatively straightforward, and has been used in power tools for decades.
The downside is that physical contact creates friction. Over time, the brushes wear down, and the motor can generate more heat during operation.
That doesn't make brushed drills bad. It simply means the motor has components that experience physical wear.
How a Brushless Motor Works
A brushless motor removes those physical brushes and uses electronic circuitry to control the motor.
Without brushes rubbing against a commutator, there is less mechanical friction inside the motor.
According to DEWALT, its brushless motor technology provides benefits including reduced maintenance, longer motor life, more power, and longer runtime from the same battery.
DEWALT also states that its brushless motors can provide up to 57% more runtime than its standard brushed motors, although the exact advantage varies according to the tool and operating conditions.
That last point is important.
Don't interpret a manufacturer's maximum runtime comparison as a universal rule for every drill from every brand.
Brushed vs. Brushless Drill: The Key Differences
Here's the quick breakdown:
| Feature | Brushed Drill | Brushless Drill |
|---|---|---|
| Motor brushes | Yes | No |
| Mechanical brush wear | Yes | No |
| Maintenance | Generally higher | Generally lower |
| Motor efficiency | Generally lower | Generally higher |
| Heat generation | Generally higher | Generally lower |
| Battery efficiency | Generally lower | Generally higher |
| Typical purchase price | Lower | Higher |
| Long-term heavy use | Can work well | Often advantageous |
| DIY suitability | Excellent for many tasks | Excellent |
| Professional use | Depends on workload | Often preferred |
The word “generally” matters here because drill performance isn't determined by motor technology alone.
Gearbox design, electronics, battery capacity, torque, speed, ergonomics and overall construction all influence how a cordless drill performs.
Why Are Brushless Drills More Expensive?
The price difference isn't simply because manufacturers decided to put the word “brushless” on the box.
Brushless systems require electronic control components that manage how power is delivered to the motor.
You're therefore paying for more than a different motor design.
A brushless drill may also belong to a manufacturer's higher-performance tool range, meaning the price difference can include upgrades to the gearbox, controls, chuck, battery system or other components.
That's why comparing two drills based solely on brushed versus brushless can be misleading.
A better comparison looks at the complete tool package.
Does Brushless Mean More Power?
This is one of the most common misconceptions.
A brushless motor can offer efficiency advantages and may enable manufacturers to deliver strong performance, but “brushless” doesn't automatically mean that every brushless drill produces more torque than every brushed drill.
Tool design matters.
For example, modern 20V brushless impact drivers can deliver very high torque and multiple speed settings. DEWALT's current 20V MAX XR brushless impact-driver range includes models with multiple speed modes and high torque outputs.
But don't compare a compact brushless drill with a heavy-duty brushed drill and assume the brushless model automatically wins every specification.
Compare the actual numbers.
The Battery Runtime Advantage
For cordless tools, efficiency matters because you're carrying your power source with you.
A less efficient motor can waste more energy as heat and friction. A brushless design reduces some of those mechanical losses.
That can translate into more work from the same battery under comparable conditions.
This becomes especially noticeable when you're working through a large project.
Imagine installing cabinet hardware, building a deck, assembling furniture, drilling pilot holes, or working through a long construction day.
A few minutes of additional runtime may not sound important on paper.
Repeated across dozens or hundreds of tasks, however, battery efficiency becomes much more useful.
DEWALT specifically describes its brushless technology as providing longer runtime from the same battery and says its brushless motors run cooler than its brushed units.
Brushless Motors and Heat
Heat is an enemy of many mechanical and electrical components.
Because brushed motors rely on physical contact between brushes and the commutator, friction occurs during operation.
Brushless motors eliminate that particular source of friction.
That doesn't mean a brushless drill cannot become hot. High-load drilling still creates heat through electrical resistance, mechanical load, gearing and other factors.
However, eliminating brush contact can contribute to a cooler-running motor design.
For someone occasionally drilling a few holes into softwood, this distinction may barely matter.
For someone using a cordless drill repeatedly throughout the day, it can become much more relevant.
What About Maintenance?
This is one area where the difference is straightforward.
Brushed motors contain brushes that wear over time.
Eventually, those components may need replacement.
Brushless motors don't use those physical motor brushes, which removes that particular maintenance item.
DEWALT identifies the lack of brush replacement as one of the maintenance benefits of brushless technology.
Of course, a brushless drill isn't maintenance-free.
The chuck, gearbox, battery, electronics and other components can still experience wear or failure.
So think of brushless as lower maintenance in relation to the motor, not as a lifetime guarantee.
When a Brushed Drill Still Makes Sense
Here's where the 30% premium question gets interesting.
If you're a casual DIY user, a brushed drill can still make plenty of sense.
Consider someone who:
- Drills a few holes every month
- Assembles furniture occasionally
- Handles small home repairs
- Doesn't need maximum battery runtime
- Already owns compatible batteries
- Wants to keep the initial purchase price low
For that type of user, paying extra for brushless technology may not produce enough practical benefit to justify the additional upfront cost.
A good brushed drill can still be perfectly capable for ordinary household tasks.
The key is buying a tool that matches the workload.
When Brushless Is Easier to Justify
The equation changes when the drill becomes a regular part of your working life.
A brushless cordless drill can make more sense if you:
- Use your drill several times a week
- Work on construction or renovation projects
- Frequently drill harder materials
- Need longer battery runtime
- Want lower motor maintenance
- Expect to keep the tool for many years
- Are building a professional-grade cordless tool collection
In those situations, the higher upfront cost can be easier to justify because you're using the efficiency and durability advantages more frequently.
You're not really paying for a label.
You're paying for a tool designed around a different motor architecture.
What Is a 20V Brushless Cordless Drill Driver Set?
If you're shopping for a 20V Brushless Cordless Drill Driver Set, don't stop at the motor description.
Look at everything included in the kit.
A complete cordless package can be more useful than buying a bare tool because you may receive a compatible battery, charger and additional tool or accessories.
This is particularly important when you're entering a cordless platform for the first time.
Once you own batteries and chargers from a particular system, future tool purchases can become easier because compatible batteries may work across multiple tools.
That's one reason combo kits can be attractive for homeowners, DIY enthusiasts and tradespeople building a tool collection.
Drill Driver vs. Impact Driver: Why Combo Kits Can Be Useful
A drill driver and an impact driver aren't interchangeable twins.
They're more like two members of the same toolbox family.
A drill driver is useful for drilling holes and driving screws where control and versatility are important.
An impact driver is designed primarily for fastening and can provide high torque through its impact mechanism.
For larger screws, long fasteners and demanding fastening work, an impact driver can make the job considerably easier.
Modern cordless systems often package both tools together, giving users two different tools for different tasks.
DEWALT's 20V MAX range, for example, includes both cordless drills and impact drivers, with brushless models designed for demanding applications.
A 20V DEWALT Combo Kit Worth Considering
For shoppers looking for a combination of cordless drilling and fastening capability, a DEWALT 20V MAX cordless drill and impact driver combo kit can be an interesting option.
The specific product available through TotalFindz is a refurbished DCK277C2 kit and is listed with a DEWALT warranty.

Because this is a refurbished product, shoppers should pay particular attention to the exact listing details, included accessories, battery condition, warranty terms and seller information before purchasing.
That's especially important with cordless tools because battery condition can have a meaningful impact on real-world performance.
Is the 30% Brushless Premium Worth It?
There isn't a universal answer.
Instead, think about the cost per use.
If you use a drill twice a year, paying significantly more for a brushless motor may not be necessary.
If you use the tool several times a week, the equation changes.
Better efficiency, reduced motor maintenance, potentially longer runtime and cooler operation can become valuable over hundreds of hours of use.
For professionals, contractors and serious DIY users, those benefits may matter much more than the initial price difference.
For occasional homeowners, a capable brushed drill can still be a sensible way to keep costs down.
How to Choose Between Brushed and Brushless
Before buying, ask yourself five questions:
1. How Often Will I Use It?
Occasional use favors value. Frequent use makes efficiency and durability more important.
2. What Materials Will I Drill?
Wood, drywall and basic household tasks have different requirements from heavy-duty construction or repeated drilling in harder materials.
3. How Important Is Battery Runtime?
If you frequently work away from an outlet or need to complete long jobs between charges, efficiency becomes more valuable.
4. Am I Building a Cordless Tool Platform?
If you're planning to buy multiple cordless tools from the same battery ecosystem, consider the long-term system rather than one drill.
5. What's Included in the Price?
Compare batteries, chargers, accessories and warranties, not just the tool body.
A “cheaper” drill can become less attractive if you need to purchase a battery and charger separately.
The Bottom Line
So, is the 30% price premium for a brushless drill worth it?
It depends on the workload.
Brushed drills remain useful, particularly for homeowners and occasional DIY users who prioritize a lower upfront cost.
Brushless drills offer a different set of advantages: reduced brush-related maintenance, potentially better efficiency, cooler operation and longer runtime under comparable conditions.
For someone who uses a cordless drill regularly, those advantages can become meaningful over time.
For someone who pulls the drill out of the garage a handful of times each year, the extra money may be harder to justify.
The smartest purchase isn't necessarily the drill with the newest technology.
It's the drill whose motor, battery system, torque, speed, accessories and price match the work you actually do.
And if you're comparing a 20V Brushless Cordless Drill Driver Set, remember that the motor is only one part of the equation. Look at the entire kit, because the best value often hides in what comes inside the box.
