What is a Brushless Drill?

By Herbert Dorman

What is a Brushless Drill?

If you are searching for a drill to purchase, then you might have researched for brushless and brushed model drills.

Did you fall in a dilemma due to the research to make the right decision of buying a brushless or brushed motor?

Well, shake hands with me, and I will assist you in making the right decision.

In fact, the brushless drill was introduced a few years back. They did not take much time to make the ground on the traditional brushed motor. As a result, now they occupied 30% – 50% cordless drill market, isn’t it astonishing?

However, let’s discuss what is a brushless drill and what are the differences between a brushless and brushed drill. This way, I believe, you will be able to make a precise decision.

Let’s move on.

 

Brushless Drill – Definition

what is a brushless drill

I am pretty sure, when you first hear about “brushless drill”, you wrinkled your eyes. Because many of us are unaware of the function of a drill.

Let me make you clear on this.

Initially, when the drill was invented, it consisted of 4 different parts to run the motor effectively. The parts were carbon brushes, magnets, armature, and the commutator. 

Combination of all these parts was assisting to generate a drilling motion that was helping to run the machine. This is how traditional drill works.

On the other hand, the brushless motor doesn’t contain the commutator, and the carbon brushes part. 

Means in terms of design, they are different from the traditional drill as well as its working procedure is also varying than a conventional drill. Absence of these two parts didn’t create any problem to run a brushless motor. And unbelievably, a brushless motor is providing more efficient performance with less friction than a traditional drill.

This is the significant difference between a brushless and brushed drill.

We will look into more details below.

 

Brushless VS. Brushed drill

 

There are a lot of differences available between these 2 types of drill. Both drills can give you the same output following different working procedures. When you are talking about performance, durability, efficiency, reliability, you will find that a brushless drill is giving you the highest benefit than a brushed drill.

  • Energy-Efficient

As a brushless drill doesn’t have any brush which is not creating any friction to anything, it means a brushless motor is more energy-efficient than a brushed drill. Thus, the consumption of battery is less in a brushless drill, and the battery will last 50% more than a brushed drill battery.

This saved energy converts into more power and no loss happens because the brush doesn’t have any mechanical limitations.

For this reason, a brushless drill is more energy-efficient than a brushed drill.

  • Highly Responsive

A drill that has a brushless motor can adjust its power supply, torque and speed based on the work that you have in your hand. It means if you are working with lightweight material like creating a hole in drywall, it will provide exact speed and torque that is enough to make the hole. Thus, it will not use more energy, speed and power supply.

But a brushed drill will always provide you the same speed, torque and power supply when you are performing either a lightweight or heavyweight task.

Isn’t a brushless motor highly responsive to your task?

  • Performance

As we already know, the brushless drill doesn’t contain any brush, and due to this, no friction is there inside the brushless drill. So, it can provide you high power and speed instantly.

And due to the friction, a brushed motor shows inconsistent performance to give you high power and speed during operation.

You will receive 15% – 30% more increased performance from a brushless drill due to the less friction characteristic.

  • Easy Maintenance

You need to replace the brush of a brushed drill every after 50 – 60 hours. But as the brushless motor doesn’t have any brush, it doesn’t require anything to replace after a certain amount of time.

  • Small is size and Lightweight

The brushed motor is bigger than a brushless motor. Due to this, the overall size of a brushless drill becomes smaller than a brushed drill.

Brushless motor design is 25% less compact than a brushed drill.

This characteristic of a brushless drill is giving you another 3 benefits.

Lightweight, portable and easy storing.

Yes, you can carry a brushless drill at any place. And due to the compact design, storing is also easy.

  • Long Service

A brushless drill has no friction, means no formation of excessive heat. And this drill is 50% cooler than a brushed drill.

Also, as the brushless drill doesn’t create excessive heat, there is no vent to make it more relaxed. No vent means, no dirt can go inside the drill. Due to this feature, a brushless motor provides consistent performance for an extended period.

 

Which One Should I Buy, Brushless or brushed drill?

 

In recent times, the brushless motor is taking charge of heavy-duty tasks. So if you have serious projects in your hand, a brushless drill will be the best choice. You will get more power, high speed, reliable performance from a brushless drill.

But if you are a DIY lover and hardly use a drill to make any hole, you should go with a brushed drill. Because DIY lovers or homeowners don’t think about long period service or secure maintenance benefits.

However, you will get a lot of benefits with brushless drills, although they are pricier than brushed drills. But when you are getting a mouthful of benefits, won’t you want to pay a bit more $ to buy a great tool? Who knows, you will always require lightweight work to do?

 

Summing Up

A person who works in the automotive industry, s/he knows how vital a brushless motor is. There is no doubt using a brushless drill is making a task much easier for a contractor, which is why you will never regret investing in a brushless motor.
