Brushless Vs. Brushed Drills: Which One Should You Choose?

Cordless drills are becoming more popular as well as valuable. However, many people still cannot choose between Brushless Vs. Brushed Drills if you are one of them! Follow our next share in this article to get the most necessary information! 

Between brushless vs. brushed drills, which one should you choose?

If you want to choose a cheap cordless drill, easy to maintain when repairing but not very effective, you should select a brushed drill.

On the contrary, with a higher price, but a brushless drill will give you all the advantages that are far superior to a brushed drill. However, it can only be replaced, not repaired.

Both types of drills are different in construction, operation and working efficiency. Each type has its advantages.

Choosing between these two types of drills is quite tricky. You should consider your current budget and your intended use.

Brushless Vs. Brushed Drills Which One Should You Choose

To find out which drill you really should choose. Please scroll down and follow our detailed analysis and sharing!

What is a Brushed Drill?

The brushed drill is a drill with a brushed motor. It uses a brush motor to operate and work.

Brushes come in different sizes. It has a standard shape that is square or rectangular.

Brushed motor

A traditional brush motor consists of a brush, an armature, a magnet ring, and a commutator. They work together to make the brushed drill work.

During operation, the magnet and brush are stationary. Conversely, the commutator and armature rotate together on the magnet axis.

The armature consists of copper coils coupled together. During operation, the commutator transfers a charge to the armature causing the armature to rotate.

Pros of brushed drill

  • The brushed drill is very popular in the market, easy to get expert advice
  • Easy maintenance
  • No cost to buy new or repair

Cons of brushed drill

  • The inefficient operation, working efficiency is only from 75% to 80%
  • Brushes wear out quickly, so they need to be replaced every 50 to 60 hours
  • The engine easily appears and attracts a lot of dust. Dirt promotes faster brush wear
  • It will lose torque during overdrive or sudden acceleration

What is a brushless drill?

A Brushless drill is a cordless drill with a brushless motor. They work the exact opposite of brushed drills.

Brushless motor

Unlike brushed motors, brushless motors do not include brushes and commutators. Here, the manufacturer has swapped the position of the magnet and the coil.

The brush and commutator is a small circuit board that helps distribute energy to the coils. This board can sense and adjust the input power source to support the machine’s work efficiently.

Pros of brushless drill

  • Energy saving
  • Quick response, flexible
  • More powerful and high performance
  • Compact design
  • Low maintenance
  • Long drilling time

Cons of brushless drill

  • High selling price
  • You cannot repair it, and you can only replace it

What is the difference between brushless and brushed drill?

The difference between these two types of drills is always something that many people are curious about. Right from the first name, we can also recognize their main difference.

However, in the following, I will clarify the differences between these two types of cordless drills. This is also a good basis for you to make a selection decision.


As noted above, brushless drill motors do not use brushes. It uses magnets instead of brushes to generate power.

In contrast, a brushed drill uses a brush and a commutator to power the motor. Brushed motors have windings on the armature as well as permanent magnets on the stator.

Brushless motors have the exact opposite position. It has permanent magnets on the rotor and coils on the stator to rotate the rotor.

In the brushless motor, there will be a small circuit board. This board is capable of sensing and adjusting the energy they draw in different situations.

Which means it can effectively regulate the energy it uses. But the brushed motor is different, and it always runs fastest when the switch is on.


The Brushed drill is the first cordless drill. They appear long before brushless drills. So physically, they don’t have much improvement.

Brushed drills are larger and heavier than brushless drills. Using it is also somewhat more difficult because the handle requires a reasonably large force.

Working performance

Due to the structure and physical properties, brushed drills are not as effective as brushless drills. It is only 75 to 80% effective, while the brushless drill is 80 to 90% effective.

A Brushless drill can still maintain high torque and durable power under continuous operation and sudden acceleration.

But the brushed drill is not like that. It will lose torque when operating at high power.


Price is an issue that many shoppers care about.

Due to the outstanding advantages, brushless drills are much more expensive than brushed drills.

When it comes to parts problems, brushed drills are also easier to repair and maintain. It is also less expensive to buy components.

A Brushless drill is not so easy. When it appears a problem, you will often have to replace it with a new one that cannot repair.

Bottom line

  • The working efficiency of the brushless drill is higher than that of the brushed drill. You can sustain the torque 
  • It would be best if you change the scanned brushed drill every 50 – 60 hours of use. But the brushless drill is not
  • The brushed drill is large and durable
  • A Brushless drill requires little maintenance but you will have to replace it if problems arise

Why should you choose a brushed drill?

Easier to maintain

Brushed drills are tools that require more maintenance, but they are easier to repair. Components for maintenance also cost very little.

The main maintenance is that you regularly change the brush to help the machine work better.

The brushed drill has been around for quite a while. It’s popular with many people, so it’s always easy to ask for their experience. They can give you some tips for better use of the drill.

Lower price

With the brushless drill, it’s really cheap in terms of both purchase price and spare parts.

Most of the technologies that brushed drills have are old technologies, so you don’t have to spend too much money on them.

Compared to brushless drills, they are actually a lot cheaper.

Why should you choose a brushless drill?

Energy saving

The brushless motor operates at up to 90% efficiency. Much higher than brushed. This means that during operation, there will not be much energy consumed.

It saves battery cleaning time and energy for you.

Quick response

Thanks to the small circuit board, the brushless can automatically adjust the speed and torque more quickly. It can recognize the materials it is working with and adjust accordingly.

Virtually maintenance-free

A Brushless drill has no brush, meaning your maintenance is entirely unnecessary.

More compact

Brushless drills are smaller and lighter. You can use them continuously for a long time without worrying about hand fatigue.

The drill lasts longer

Because there is not much friction and wear of the motor, the brushless drill can work longer. Friction is low, so it produces almost no heat.

Low operating temperatures offer an advantage to the drill motor and battery. It makes both the engine and the battery safer and much more durable.

Why should you spend more money on a brushless drill and not a brushed drill?

We really need to reflect and clarify this issue. As mentioned above, brushless drills cost a lot more than brushed drills.

This will not happen naturally because brushless drill has many modern technologies and its way of working is much more efficient.

You can see that through the following analysis and sharing:

Can run longer with less energy

I have to repeat once again that brushless drills work more efficiently thanks to the low-friction motor. It also uses less power during operation.

The small circuit board can sense and regulate the power it draws. It doesn’t take up as much electrical energy continuously in the gas it doesn’t need.

From there, the drill’s battery can also increase its life and extend its use time per charge.

More reliable

In fact, you won’t have to do any maintenance or part replacement with a brushless drill.

It has no brush on the drill, so there will be no wear and tear, resulting in no replacement.

With a brushed drill, you will have to replace the brush every 60 hours of use. But brushless drills are not.

While replacing the brush is cheap and straightforward, it’s virtually inexpensive. But having to change the brush constantly will take time and many times add up to a large amount of money.

If you do not change the brush in time, you may lose torque while in use.

It can see that the brushless drill is entirely worth the money you spend. They are highly efficient and do not require constant care.

In summary, brushless motors can be more potent than traditional brushed drills. Brushless drills are also more intelligent tools as they have a self-adjusting circuit board.

Although brushed drill works with less efficiency, it is difficult to prolong the life and battery. But they come at a reasonable price and still do some tasks well.

We can better summarize the brushless vs brushed drill:

  • Less sustaining and longer life – due to no brushes
  • More power – fewer restrictions in power-dissipating engines
  • Longer run time and less battery charge – due to efficient use of energy


After all the above analysis, we can see that a brushless drills work much more effectively than brushed drills. Its lifespan is also longer. But the price you pay to have it is not low.

Brushed drills are cheaper with good performance but require more care and maintenance.

Each type of machine will have certain suitability for you. Hopefully, through our sharing above, you will make the correct choice!
