The world of power tools frequently prompts the brushless vs non brushless drill question. Milwaukee Tool, a prominent manufacturer, offers both types, making this comparison particularly relevant for consumers. The increased runtime often associated with brushless drills results from their efficient motor design, a key attribute valued by professionals. Choosing between a brushless vs non brushless drill often comes down to specific needs and understanding their motor technology, directly impacting the overall performance of the tool.

Brushless vs. Non-Brushless Drill: Finding the Right Tool for the Job
Choosing the right drill can be confusing, especially when considering the key difference between brushless and non-brushless (brushed) motors. This breakdown will examine the core differences, advantages, and disadvantages of each type to help you make an informed decision.
Understanding the Core Technology
At its heart, the distinction between brushless and non-brushless drills lies in their motor design and how they generate power.
Brushed Motor Basics
Traditional drill motors, often called "brushed" motors, use carbon brushes to deliver electricity to the spinning armature.
- How it Works: The brushes physically rub against the commutator, a rotating part of the motor, creating a connection that energizes the motor’s coils.
- Friction and Wear: This constant friction generates heat and causes the brushes to wear down over time.
Brushless Motor Basics
Brushless motors, on the other hand, eliminate the need for physical brushes.
- How it Works: Instead of brushes, an electronic controller energizes the motor’s coils. This controller uses sensors to determine the armature’s position, allowing it to precisely deliver power.
- Reduced Friction: This design eliminates friction and wear, resulting in a more efficient and durable motor.
Performance Comparison: Key Differences
The different motor designs impact several aspects of drill performance.
Power and Efficiency
- Brushless: Generally offer higher power output and greater efficiency. They deliver more torque per watt of energy consumed, meaning you can often get more work done on a single battery charge.
- Brushed: Can be less efficient, as a portion of the energy is lost to friction. This can translate to shorter run times and potentially lower power delivery.
Runtime
- Brushless: Due to their efficiency, brushless drills often boast significantly longer runtimes compared to their brushed counterparts.
- Brushed: More frequent battery changes or charging may be needed when using a brushed drill for extended periods.
Lifespan and Maintenance
- Brushless: The absence of brushes significantly extends the motor’s lifespan. They typically require less maintenance.
- Brushed: Brushes are a consumable part and will eventually need replacing. This adds to the maintenance cost and downtime.
Size and Weight
- Brushless: While the motor itself might not always be drastically smaller, the overall design can sometimes allow for a more compact and lighter drill body, especially with advancements in technology.
- Brushed: The traditional motor design can sometimes lead to bulkier and heavier drills.
Cost Considerations
The initial investment is another crucial factor to consider.
Initial Price
- Brushless: Typically more expensive upfront than brushed drills due to the advanced technology and components involved.
- Brushed: Generally more budget-friendly, making them an attractive option for casual users or those on a tight budget.
Long-Term Costs
While brushed drills have a lower initial price, the cost of replacing brushes and the potential for shorter tool life can offset the savings in the long run.
Application and Use Cases
The best choice depends on the intended use of the drill.
- Brushless: Ideal for professionals or serious DIYers who require high performance, long runtime, and durability for frequent or demanding tasks. Examples include construction, carpentry, and mechanical work.
- Brushed: Suitable for light-duty tasks around the house, occasional projects, or users who don’t require the power and runtime of a brushless drill. Examples include hanging pictures, assembling furniture, and basic repairs.

| Feature | Brushed Drill | Brushless Drill |
|---|---|---|
| Motor Type | Brushed | Brushless |
| Efficiency | Lower | Higher |
| Runtime | Shorter | Longer |
| Lifespan | Shorter | Longer |
| Maintenance | Requires brush replacement | Minimal |
| Initial Cost | Lower | Higher |
| Power Output | Typically lower | Typically higher |
| Best Use Cases | Light-duty tasks | Heavy-duty/professional |
Brushless vs Non Brushless Drill FAQ
Here are some frequently asked questions to help you better understand the difference between brushless and non brushless drills.
What’s the core difference between a brushless and non brushless drill?
The fundamental difference lies in the motor. A non brushless drill uses carbon brushes to transfer electricity, creating friction and wear. A brushless drill, on the other hand, uses electronic controls to directly power the motor, eliminating the need for brushes.
How does a brushless motor impact the power and efficiency of the drill?
Brushless motors are generally more efficient. This means they deliver more power to the drill chuck using less battery, resulting in longer run times and often increased torque compared to their non brushless counterparts. The efficiency directly impacts the overall performance of a brushless vs non brushless drill.
Are brushless drills always the better option for every user?
Not necessarily. While brushless drills offer superior performance and longevity, they typically come with a higher price tag. For occasional, light-duty use, a non brushless drill might be sufficient and more budget-friendly. The best choice depends on your needs and budget.
How does the lack of brushes affect the lifespan of a brushless drill?
Because there are no brushes to wear down and replace, brushless drills generally have a longer lifespan. This reduced maintenance contributes to a lower total cost of ownership over time, making the investment in a brushless vs non brushless drill potentially worthwhile for frequent users.
So, which one are you leaning towards – brushless or non-brushless? Hopefully, you’ve got a clearer picture of the brushless vs non brushless drill debate now! Get out there and start drilling!
