Milwaukee, one of the most well-known power tool manufacturers, has provided sleek, high-performance products for generations.

They’ve also made a name for themselves as one of the greatest brands of cordless power tools.

Milwaukee gasoline tools appear to be the most potent and high-quality range available and are widely used in business and household settings.

As for Milwaukee fuel vs. non Fuel, this well-known gasoline line’s intriguing brushless motor technology is famous. 

Milwaukee launched the Fuel series of brushless tools in 2012, distinct from its product range. The M18 is a range of lithium-ion battery-powered cordless heavy machinery.


Milwaukee’s M18 series was released in 2008 as an improvement to their M12 system.

Both sorts of Milwaukee power tools, like the FUEL series, are meant to be long-lasting, reliable, and for professionals like building workers, architects, and contractors.

Milwaukee Fuel:

Milwaukee has been working to increase the performance of its M18 cordless tool series since the introduction of its red lithium batteries.

Milwaukee Fuel power tools are contractor-grade mechanical devices that are solidly made, have a more significant effect on the activity, and are water and heat resistant

Fuel is an upgraded Milwaukee gear line that provides even more power, endurance, and longer survival durations than the non-Fuel line, which has been around for decades.

Although the Fuel tools utilize the same M12 or M18 battery sizes, they differ in significant ways. The most critical aspect of FUEL is battery life.

FUEL monitors battery usage to ensure that it stays within acceptable limits. It prevents a tool from drawing too much electricity and harming the battery.

Milwaukee non-Fuel:

The non-fuel version works in the same way as a fueling drill when it comes to driving screws. Relying on your demands, non-fuel equipment powered by 4Ah batteries may be enough.

The significant distinction between Milwaukee fuel and a Milwaukee brushless M18 is the motor’s power. The M18 Fuel, on the other hand, outperforms the non-fuel M18 by 50 percent

Non-fuel lines, which are less robust but still produce virtuous results, are a good option if you require a cheap tool. These tools are within your budget.

However, they function poorly in comparison to the gasoline line. A non-fuel fee is a cost of producing and delivering energy to your house or company that is not covered by the cost of Fuel, such as the cost of production machines and maintaining infrastructure.

Brushless vs. brushes motor:

Brushless motors work by reversing the architecture of a brush motor. Around the framework, there have been no commuter rings.

Instead of being the inner ring, the electromagnet motor is now the outside ring, removing the requirement for brushes to run the system.

Although the inner rotor, or armature, is still made of copper wire, the motor has been substantially rebuilt.

Brushes were utilized in conventional power tool motors for many decades to achieve the desired push-pull action. Meetings are visible in such engines, and while they have certain practical benefits, they have one crucial disadvantage: friction


Since there is direct interaction, friction produces heat, which causes difficulties that can reduce the motor’s lifespan.

A typical brush motor generates heat, limiting the time you may run it unless you want it to overheat. Additionally, physical touch increases the likelihood of a breakdown.

Brushless electric motors contain fewer components than brush-based motors. There are fewer things that can go wrong, which means fewer repairs and longer service life. Aside from the casing, trigger, and grip, a brushless electric motor only has the following parts:

  • An encircling electromagnet surrounds the outside fixed or constant magnet.
  • Copper windings make up the inner armature or rotor.
  • The polarity signals are controlled by a computerized circuit board.

With all of the advantages and benefits that brushless electric tools provide, you may expect them to be significantly more expensive.

Brushless tools are not priced comparable to brushed tools, which is deceptive.

Brush motors have the benefit of being simple to set up and run without needing a digital drive circuit in situations where the controller’s performance is not required.

Important factors:

There are certain factors that you need to consider while choosing Milwaukee fuel vs. non Fuel. 

  • Performance: You may now choose the most efficient and powerful option for your task. The Milwaukee gasoline motor functions admirably and delivers high-quality operation. The M18 Fuel brushless is a new compact design that is well-built and produces better results. One may choose the ideal one for themselves based on its build, power, and capabilities.
  • Cost: If affordability is your primary issue, you may pick from the non-FUEL range of power tools, which are less capable but still quite dependable. If you want a robust device, choose an M18 brushless or M18 Fuel, more lightweight power tools built for use in tighter places.
  • Technology: Milwaukee’s FUEL range of power tools features several improvements that contribute to making them some of the most sought-after power tools on the market. The new Milwaukee gasoline is powerful enough to make the process go faster and easier. The FUEL series offers a robust collection of tools for heavy-duty usage thanks to innovative technology that integrates the Power state, Red lithium battery, and Redlink breakthroughs.
  • Battery: M18 batteries may be used with both ordinary M18 and M18 FUEL variants. The new Red lithium battery pack in the M18 Fuel, on the other hand, will give you much greater battery life. Brushless motors drain less power from the battery than motors with brushes because they require less energy to run. As a result, your battery will last longer since less force is needed to do the same work. Brushless motors are an exception to this rule.
  • Speed: Brush motors consume more effort to overcome the resistance that is intrinsic in the design. The brushless architecture allows the gadget to raise its RPM with minimal obstruction. Higher speeds provide more adaptability and potential since they let you blast through more complex materials while putting less heat and impact on the engine.
  • Safety: for sure, safety comes at first. Brushless motors are secure since their design eliminates the potential of sparks forming. This is due to the absence of physical touch as compared to a brushless motor. There is no risk of being burnt in this manner if there are no sparks. It’s also preferable to use when there’s combustible stuff nearby.
  • Durability: Because brushless motors have fewer components, they are easier to detect and fix when a problem arises. After all, in the design of a brushless motor, there are only so many components. As a result, compared to a brushless motor, you can perform the repair and get back to work faster.
  • Portability: The control you have over a brushless motor at lower speeds is one of the more subtle changes. Motors with brushes oscillate due to the inherent vibrations, making them more challenging to regulate. Control concerns become more complicated at lower speeds, as vibrations mixed with the material result in a less accurate performance. Brushless motors produce fewer vibrations, allowing you to exert more access to the device even at average speeds.

Which is better?

Brushless motors are superior to brushed motors in terms of performance. These motors are made out of high-quality tools and materials.

The Milwaukee Fuel is well worth the money. It is distinguished because of its upkeep, efficiency, reduced heating capacity, and improved functionality. 


The fuel line is strong, and drilling through leaning walls is no problem for it. Brushless tools aren’t as resistant to heat, dust, moisture, or cold as brushed tools are.

They are also more expensive to own in the long run and are challenging to fix. You may change brushes out in a matter of minutes. Brushless motors offer relatively little benefit on linear loads. 


Brushless motors, in brief, replace older brushed motors technology and provide greater power with less heat. Brushless motor tools use less energy to function and have a better battery life, as you’ve undoubtedly heard.

Brushless tools may appear to be more costly than traditional brush motor control.

The majority of this is correct. Brushless electric motors outlast brushed motors by running cooler, longer, and using less modern.

On the other hand, Brushless electric tools are not always more expensive than tools with brush technology.

Thanks to advancements in Milwaukee’s technology innovations, this is especially true with cordless power tools. Friction is created by the constant contact between the fixed brushes and the rotating rotor in brushed electric motors

Friction creates heat and leads to wear over time. Electric tools that are brushed get heated and ultimately wear out. You know the brushes are worn when you squeeze the trigger and witness an arching spark within the motor case.

We hope this guide helped figure out Milwaukee fuel vs. non Fuel; you may choose that suits you best.
