Brushless vs Brushed Motor Tools
Choosing between brushless and brushed motor tools can impact your project's efficiency and your wallet. This guide breaks down the real-world differences in power, runtime, cost, and maintenance to help you pick the right motor for your needs.
Quick answer
Brushless motors are more efficient, deliver more power, and last longer, making them ideal for frequent or heavy-duty use. Brushed motors are cheaper and simpler, suitable for occasional DIY tasks. For most buyers, a brushless tool like the DeWalt DCD805 or Milwaukee M18 Fuel offers the best long-term value.

DeWalt DCD805 Brushless Drill
Best-in-class power and runtime for a compact drill.
| Feature | Brushless Motor | Brushed Motor |
|---|---|---|
| Efficiency | Up to 50% more efficient | Lower efficiency, more energy lost as heat |
| Power & Torque | Higher torque and consistent power | Lower torque, power drops as brushes wear |
| Runtime | Longer per battery charge | Shorter runtime |
| Maintenance | Minimal, no brushes to replace | Brushes wear out and need replacement |
| Cost | Higher upfront cost | Lower upfront cost |
| Weight | Often lighter and more compact | Can be heavier due to larger magnets |
| Lifespan | Longer, often 10+ years | Shorter, brushes may need replacing every 2-3 years |
| Noise | Quieter operation | Louder due to brush friction |
What is a Brushed Motor?
A brushed motor uses carbon brushes that physically contact the rotating commutator to deliver electricity to the windings. This design is simple, inexpensive, and has been used for decades in power tools. The friction between the brushes and commutator creates heat and wear, which reduces efficiency over time and limits the motor's lifespan. Brushed motors are common in entry-level and budget tools.
What is a Brushless Motor?
A brushless motor eliminates carbon brushes entirely. Instead, it uses an electronic controller to switch the current between the motor windings. This design reduces friction, heat, and energy loss, resulting in higher efficiency, more torque, and longer runtime. Brushless motors are found in premium tools from brands like DeWalt, Milwaukee, and Makita. They are more expensive to manufacture but offer significant performance advantages.
Brushless vs Brushed: Which is Better for You?
The choice depends on your usage frequency, budget, and performance needs. For occasional DIY tasks like drilling a few holes or driving screws, a brushed tool is often sufficient and more affordable. For regular use, professional jobs, or demanding applications like concrete drilling or heavy-duty fastening, a brushless tool provides better power, runtime, and durability. The higher upfront cost of brushless tools is usually offset by longer battery life and reduced maintenance.
What to Check Before Buying
Consider the following factors when choosing between brushed and brushless tools:
- Usage Frequency: If you use the tool weekly or daily, invest in brushless. For occasional use, brushed is fine.
- Battery Ecosystem: If you already own batteries from one brand, check if they offer brushless tools in the same system.
- Power Requirements: For high-torque applications like drilling masonry or driving large lag bolts, brushless is superior.
- Budget: Brushless tools cost 30-50% more. Calculate the total cost including batteries and charger.
- Weight and Size: Brushless tools are often lighter and more compact, which reduces fatigue during extended use.
Mistakes to Avoid
- Buying a brushed tool for heavy use: Brushed motors lose power as brushes wear, leading to frustration on demanding jobs.
- Ignoring battery compatibility: Not all batteries work with brushless tools. Check voltage and amp-hour ratings.
- Overlooking warranty: Brushless tools often come with longer warranties, reflecting their reliability.
- Assuming all brushless are equal: Performance varies by brand and model. Check torque specs and user reviews.
