You are standing in the tool aisle. To your left is a standard cordless drill kit for $99. To your right is a nearly identical-looking drill from the same brand, but it says “BRUSHLESS” in bold letters and costs $159.
Is this just marketing hype designed to separate you from your money? Or is there actually something magical inside that plastic shell worth the extra $60?
For decades, power tools worked the same way. But recently, the industry has shifted. Every major brand—from Ryobi to Milwaukee—is pushing their “Brushless” lines as the future.
If you are a contractor drilling 500 holes a day, the answer is obvious. But what if you are just a homeowner hanging curtain rods or building the occasional planter box?
In this guide, we are going to strip away the engineering jargon and look at the practical reality of brushed vs. brushless drills for DIY. We will explain what the difference actually is, and help you decide if your projects deserve the upgrade.
The Science: What is a “Brush” Anyway?
To understand the price tag, you have to look inside the motor.
The Old School: Brushed Motors
For over a century, electric motors used small blocks of carbon called “brushes.”
-
How it works: These brushes physically touch (rub against) the spinning part of the motor (the commutator) to transfer electricity and make it spin.
-
The Problem: Friction. Because they physically rub, they generate heat, friction, and resistance. Eventually, these brushes wear down and need to be replaced, like brake pads on a car.
The New School: Brushless Motors
Brushless motors are smarter. They flip the design inside out.
-
How it works: There is no physical contact. Instead of brushes, a small computer board (electronics) uses magnets to pull the motor around.
-
The Advantage: Zero friction. No friction means less heat and no wasted energy.
The 3 Big Benefits of Going Brushless
So, why pay more? It comes down to three things: Power, Runtime, and Brains.
1. The “Smart” Battery Life
Because there is no friction wasting energy as heat, brushless motors are incredibly efficient.
-
The Result: You can get up to 50% more runtime on a single battery charge compared to a brushed drill. If you hate constantly running to the charger in the middle of a project, this is a game-changer.
2. More Power in a Smaller Package
Brushless motors don’t need the bulky housing for the carbon brushes. This allows manufacturers to make the tool shorter and lighter while delivering more torque.
-
Why it matters: If you are squeezing into a tight cabinet to fix a hinge, a compact brushless drill fits where a bulky old drill won’t.
3. The “Brain” Factor
Brushless tools have onboard electronics that brushed tools lack.
-
Example: If you push a brushed drill too hard, it keeps trying until it smokes and burns out. A brushless drill is smart enough to sense the resistance and shut itself off to protect the motor. It effectively refuses to let you kill it.
The Argument for “Brushed” (Why Buy the Cheap One?)
So, if brushless is so great, why do they still sell the old ones?
Price.
Brushed technology is simple, proven, and cheap to manufacture. If you are buying a drill just to assemble IKEA furniture twice a year or hang a few pictures, a brushed drill is absolutely fine. It is reliable “enough.”
Many DIYers started with a cheap brushed drill and used it for 10 years without issue. You don’t need a Ferrari to drive to the grocery store.
The Decision Matrix: Which One Do You Need?
Still on the fence? Here is my honest recommendation based on what kind of DIYer you are.
Stick with BRUSHED (Save Your Money) If:
-
You are a “Just in Case” Homeowner. You need a drill for occasional repairs, hanging art, or assembling furniture.
-
Budget is Tight. You would rather save the $60 to buy lumber or paint.
-
You rarely use it for long periods. If you never drain a battery in a single day, the efficiency boost doesn’t matter to you.
Upgrade to BRUSHLESS (Spend the Money) If:
-
You build things. If you plan to build a deck, a pergola, or finish a basement, the extra torque and battery life are mandatory.
-
You drive big screws. Driving 3-inch deck screws requires torque. A brushed drill will struggle and overheat; a brushless impact driver will sink them like butter.
-
You value your wrists. The lighter weight makes a huge difference after holding the drill for 4 hours.
Conclusion: The First Step in Your Toolkit
The drill is the captain of your team. While a brushed drill will get you started, I almost always recommend that aspiring DIYers spend the extra money for Brushless if they can afford it.
Why? Because tools are investments. A good brushless drill will likely last you 15-20 years. That’s an extra cost of about $3 per year for a tool that is lighter, stronger, and smarter.
What’s Next? Once you have your drill sorted, you are ready to start cutting wood. A drill puts things together, but you need a saw to size them up. If you are building your workshop, your next purchase should be a saw. Check out our guide on [The 7 Best Miter Saws for Beginners] to complete your essential DIY duo.
Now, go charge those batteries and make something cool.
