Impact wrenches are essential in any shop, but which type is right for you? You might be wondering whether to go with a brushless model or a brushed one. Here we’ll take a look at the key differences between brushless and brushed impact wrenches and help you decide which one is suitable for your job. Keep reading to learn more!
What is a brushless impact wrench, and how does a brushless impact wrench motor work?
A brushless impact wrench is a power tool that uses a brushless motor to generate high torque. The brushless impact wrench motor is more efficient than a brushed motor and produces less heat and friction. This makes the brushless impact wrench ideal for use in applications where high torque is needed, such as in automotive repair or construction.
A brushless impact wrench motor works by using magnets instead of brushes to create rotational force. The magnets are mounted on the rotor and rotate around the stator. This creates a rotating magnetic field that interacts with the windings in the stator to produce torque. Because there are no brushes to generate friction, the brushless motor is more efficient and longer lasting than a brushed motor.
Advantages
- The main advantage of a brushless impact wrench over a conventional brushed model is that it is more efficient and requires less maintenance.
- Brushless motors typically have a longer lifespan than brushed motors.
- Small and lightweight, that is very handy to use in tight spaces
- Offers extended lifespan and less maintenance cost
Disadvantages
- However, brushless impact wrenches are also more expensive than their brushed counterparts.
- Another disadvantage is that brushless motors can be damaged by dust and debris, so they require regular cleaning.
What is a brushed impact wrench, and how does a brushed impact wrench motor work?
A brushed impact wrench is a powered tool that delivers high torque output with a fast hammering action, making it ideal for loosening bolts that have been tightened to extreme torque specifications.
The motor in a brushed impact wrench uses carbon brushes to transfer electrical current to the spinning armature, which creates a rotating magnetic field. This field interacts with the fixed magnets in the stator to create torque, which is then transferred to the anvil through the drive train. A brushed impact wrench is typically used for heavy-duty applications because of its higher torque output.
Advantages
- A brushed impact wrench is able to deliver high torque output with less effort.
- Less expensive than a brushless model.
- A brushed impact wrench is suitable for construction, automotive, and industrial applications.
Disadvantages
- They require more maintenance than brushless models.
- The brushes must be regularly inspected and replaced as needed to prevent damage to the motor.
- Brushed impact wrenches tend to be less efficient than brushless models, meaning that they generate more heat and can drain batteries faster.
Brushless vs brushed impact wrench – comparison
Power
There are a few key differences between brushless and brushed impact wrenches. Most notably, brushless impact wrenches are more powerful and efficient and produce less heat while working.
Weight and size
Brushless impact wrenches are also lightweight and have a longer life span than their brushed counterparts. Both types of impact wrenches can vary quite a bit in terms of size.
Cost
In terms of cost, it usually depends on the specific model and brand of each type of impact wrench. In general, though, brushless impact wrenches tend to be more expensive than brushed ones.
Drive
When it comes to the drive mechanism, brushless impact wrenches typically use a permanent magnet motor, while brushed impact wrenches use an electromagnet.
Control
As for control, brushless impact wrenches often have built-in electronic speed control that will help reduce the tool’s vibration, while brushed models typically don’t.
Maintenance
In terms of maintenance, both types of impact wrenches require periodic cleaning and lubrication. However, because brushless models have fewer moving parts, they generally require less maintenance than brushed models.
Lifespan
Finally, when it comes to lifespan, brushless impact wrenches typically last longer than brushed models. This is due to the fact that brushless motors don’t have brushes that wear out over time.
These are the key differences between brushless and brushed impact wrenches.
Brushless vs brushed impact wrench – Which is better?
When it comes to impact wrenches, there are two main types: brushed and brushless. Both have their own pros and cons, so choosing the right one for your needs is essential. Brushed impact wrenches are typically more affordable, but they require more maintenance due to the wear and tear on the brushes.
Brushless impact wrenches, on the other hand, are more expensive but require less maintenance. In terms of power, brushless impact wrenches tend to be more powerful than brushed ones. However, both types of impact wrenches are capable of delivering a high amount of torque. Ultimately, the decision of which kind of impact wrench to choose depends on your specific needs and budget.
When should we use a brushed and brushless impact wrench?
Impact wrenches are valuable tools for anyone who needs to loosen or tighten large bolts quickly. Brushed impact wrenches are cheaper and simpler than brushless models, but they are also less powerful and tend to be less durable.
If you need an impact wrench for occasional DIY projects, a brushed model will probably suffice. However, a brushless model is probably a better choice if you’re a professional mechanic or need an impact wrench for heavy-duty tasks.

Frequently asked questions
Are brushless tools worth the extra money?
Brushed motors are the traditional kind, and they are less expensive. Brushless motors offer several advantages that make them worth the extra cost. First, brushless motors are more efficient than brushed motors so that they can run for longer on a single charge. Second, brushless motors generate less heat, so they don’t overheat quickly and can be used for extended periods. Finally, brushless motors produce less vibration, making them ideal for use with sensitive materials. For all these reasons, brushless tools are worth the extra money.
Ryobi impact wrench brushed vs brushless – which is better?
While both have their benefits and drawbacks, Ryobi brushless motors provide you with more efficiency and durability. So when it comes to selecting impact wrenches, it is always better to go with a brushless model.
Ryobi’s brushless impact wrench is powered by a lithium-ion battery, which provides up to 3x the runtime of a standard NiCad battery. Plus, the brushless motor can deliver up to 700 ft-lbs of torque, making it ideal for lug nuts and other demanding applications.
In terms of price, the Ryobi brushless impact wrench is slightly more expensive than its brushed counterpart. But considering its superior performance and longer lifespan, it’s definitely worth the investment.
Are brushless tools better than a brush?
Brushed motors have been around for longer and are typically less expensive. On the other hand, Brushless motors are more efficient and tend to require less maintenance. So, which type of motor is best?
Brushless motors don’t generate as much heat, making them more efficient. This means that they can run for extended periods without overheating. Second, brushless motors tend to be more durable because no brushes are worn out, which is ideal for more demanding applications.
Finally, brushless motors usually need less maintenance than brushed motors because there are no brushes to replace.
Overall, brushless motors are better than brushed motors.
