Power tools have become indispensable companions for both DIY enthusiasts and professional tradespeople. One such reliable tool is the DeWalt power tool, known for its durability and efficiency. However, like all electrical devices, they require regular maintenance to ensure optimal performance. One of the essential maintenance tasks is changing the brushes on your DeWalt power tool. If you’re unfamiliar with this process, don’t worry! This comprehensive guide will take you step-by-step through how to change the brush on your DeWalt power tool, ensuring your tool stays running smoothly and efficiently.
Understanding the Importance of Power Tool Brushes
Before diving into the step-by-step instructions, it’s crucial to understand what brushes do in power tools and why changing them is a vital maintenance step. Power tool brushes are small pieces of carbon that conduct electricity to the motor. Over time, these brushes wear down due to friction and heat generated during use. Here’s why keeping your brushes in good condition is essential:
- Improved Performance: Worn brushes can cause the tool to underperform. Regularly changing brushes helps maintain optimal speed and efficiency.
- Extended Tool Life: By replacing worn brushes, you prevent damage to the motor, thereby extending the overall life of your power tool.
Now that we understand the significance of power tool brushes, let’s move on to the process of changing the brushes on your DeWalt power tool.
Gathering Your Tools and Materials
Before you can successfully change the brushes, it’s essential to gather all the necessary tools and materials. Prepare the following items:
Required Tools
- Flathead screwdriver
- Phillips screwdriver
- Replacement brushes (make sure they are compatible with your specific DeWalt model)
- Multimeter (optional, for testing)
- Clean cloth or rag
Safety Precautions
Safety should always be your top priority. Before starting, ensure the following:
- Unplug the tool: Disconnecting from the power source is crucial to avoid accidental starts.
- Wear safety goggles: Protect your eyes from any debris that may come loose during the process.
- Use gloves: Wearing gloves can protect your hands from sharp edges or components.
Step-by-Step Guide to Changing Brushes on DeWalt Power Tools
Changing the brushes on your DeWalt power tool can seem daunting, but following these straightforward steps will make the process much easier.
Step 1: Locate the Brush Holder
The first step is to locate the brush holder. Usually, this will be located on the side of the tool. Look for small covers or access panels that house the brushes.
Step 2: Remove the Cover
Use your flathead or Phillips screwdriver to remove the screws that secures the brush cover. Carefully place the screws in a safe location to avoid losing them.
Step 3: Remove the Old Brushes
Once the cover is removed, you’ll see the brush holders. Gently slide the old brushes out of their holders. If they are stuck, you may need to wiggle them a bit to free them up. Take this opportunity to inspect the brushes for wear. If they are shorter than three-quarters of their original length, it’s definitely time for a replacement.
Step 4: Clean the Brush Holders
Using a clean cloth, wipe down the brush holders to remove any dust or debris. This step ensures that the new brushes will seat properly and function effectively.
Step 5: Insert the New Brushes
Take your new brushes and carefully slide them into the brush holders. Ensure they are positioned correctly and are secure. You should feel a slight resistance, indicating they are in place.
Step 6: Reattach the Brush Cover
Once the new brushes are in place, reattach the brush cover using the screws you previously removed. Ensure the cover is securely fastened to avoid dislodging during operation.
Step 7: Testing the Tool
With everything reassembled, plug your DeWalt power tool back in. Before using it for a significant task, run it briefly to test the new brushes. If you notice any unusual noises or performance issues, double-check your installation.
Signs You Need to Change Your Brushes
Understanding when to change the brushes can save you from a slowdown in your work process. Here are some common signs that your DeWalt power tool needs a brush replacement:

- Sparking: Excessive sparking from the motor is a clear indication that the brushes are worn and should be replaced immediately.
- Noisy Operation: If you notice strange noises or vibrations, it may suggest that the brushes are unevenly worn.
Choosing the Right Replacement Brushes
Not all brushes are the same; therefore, always ensure you select the right brushes for your DeWalt model. Check your tool’s manual for specifications or consult with professionals at your local hardware store. Here are a few tips:
Where to Buy Replacement Brushes

What are the signs that my DeWalt power tool brushes need to be changed?
Changing the brushes on your DeWalt power tool is crucial for optimal performance. Key indicators that it’s time for a brush replacement include reduced power, frequent stalling, or unusual noises during operation. You might also notice that the motor runs hot, which can indicate excessive wear on the brushes.
Another sign to look out for is visible wear on the brush itself. If you see that the brushes are worn down to less than 1/4 inch, or if there are any cracks or chips, it is time to replace them. Regular maintenance checks can help you catch these issues early and prevent further damage to your tool.
How do I know which replacement brushes to buy for my DeWalt power tool?
To find the correct replacement brushes for your DeWalt power tool, start by checking the model number, which can typically be found on the tool’s housing. With the model number in hand, consult the DeWalt website or your user manual to find the specific brush part number.
You can purchase replacement brushes directly from DeWalt’s website, authorized retailers, or online marketplaces. Ensure that the brushes you select are specifically designed for your tool model to guarantee compatibility and performance.
Is it safe to change the brushes on my DeWalt power tool myself?
Yes, it is generally safe to change the brushes on your DeWalt power tool yourself as long as you follow the manufacturer’s guidelines. Make sure to disconnect the tool from the power source before starting any maintenance work. Wearing safety gear like gloves and goggles is a wise precaution during this process.
Familiarize yourself with the tool’s user manual to understand the disassembly and reassembly steps. If you’re unsure or uncomfortable with performing the maintenance yourself, consider seeking assistance from a professional or contacting DeWalt customer support for guidance.
What tools do I need to replace the brushes on my DeWalt power tool?
To replace the brushes on your DeWalt power tool, you will typically need a few basic tools. A screwdriver, often a Philips or flat-head, is required to remove the brush covers. Depending on the model, you may also need pliers to assist with the removal of the brushes themselves.
In addition, having a clean workspace and a small container for any screws will help keep everything organized. If your tool has a spring mechanism for the brushes, having an extra set of hands can be helpful, though it’s not strictly necessary.
Can I use my DeWalt power tool with worn-out brushes temporarily?
Using your DeWalt power tool with worn-out brushes is not advised, even if you think you can do so temporarily. Operating the tool in this condition can lead to decreased performance, overheating, and potential damage to the motor. In the worst-case scenario, it could also create safety hazards, such as electrical failures.
If you notice signs of worn brushes, it’s best to schedule time for a replacement rather than postpone. This approach not only preserves the longevity of your tool but also ensures safe and efficient operation during your projects.
How often should I change the brushes on my DeWalt power tool?
The frequency of brush changes largely depends on how often and under what conditions you use your DeWalt power tool. For tools that are used frequently or in demanding conditions, you might need to replace brushes as often as every few months. Conversely, occasional users may find that they can go longer between replacements.
To get a better idea of when to change the brushes, regularly monitor their wear during routine maintenance checks. Keeping track of your usage habits can help establish a replacement schedule that suits your specific needs and keeps your tool running smoothly.
