Steps to Replace Brushes on a Dewalt Cordless Drill
Now that you have your tools and materials ready, let’s dive into the actual replacement process. Follow these steps meticulously for the best outcome.
Step 1: Safety First
Before starting any maintenance, ensure that your cordless drill is turned off and removed from any power source. For battery-operated models, remove the battery to avoid accidental activation. Always wear safety glasses to protect your eyes from flying debris.
Step 2: Locate the Brush Covers
In most Dewalt cordless drills, the brush covers are found on the side of the motor housing. Depending on your model, you might need to consult the user manual for exact locations. They are typically secured with a small screw.
Step 3: Remove the Brush Covers
Using a Phillips screwdriver, carefully remove the screws holding the brush covers in place. Once the screws are out, gently pull off the brush covers.
Tip:
Keep the screws in a safe place to avoid losing them during the replacement process.

Take your new carbon brushes and insert them into the brush holders. Make sure they fit snugly and are orientated correctly. It’s vital that both brushes are in the same position to maintain proper functionality.
Step 6: Replace the Brush Covers
Once the new brushes are securely in place, reattach the brush covers. Align them properly and insert the screws back into their respective holes. Tighten the screws, ensuring not to overtighten them, which may cause damage.
Step 7: Reinstall the Battery
After everything is securely in place, reinsert the battery into the drill. Your cordless drill should now be ready for a test run.
Step 8: Test the Drill
Before diving into your next project, it’s wise to test the drill’s performance. Turn it on carefully and listen for any unusual noises. Ensure that it runs smoothly and operates as expected. If the drill performs well, congratulations! You’ve successfully replaced the carbon brushes.
