The DeWalt D999 drill is a powerful tool that is built for efficiency and durability. However, like any tool, it may require maintenance or part replacements over time. One crucial component to understand is the brush box, which houses the brushes that transfer electrical energy to the motor. Knowing how to remove the brush box can not only save you time and money on repairs but also enhance your understanding of your drill’s functionality. This guide provides step-by-step instructions on removing the brush box from your DeWalt D999 drill and offers some valuable insights into maintenance along the way.
Understanding the Brush Box: What Is It and Why It Matters
The brush box is an essential component of many electric drills, including the DeWalt D999. It accommodates the carbon brushes that conduct electricity from the power source to the drill’s motor. Over time, these brushes wear out and may cause a decrease in performance. A worn-out brush can result in inefficiency, leading to issues such as overheating, reduced power, and, in some cases, complete drill failure.
By learning to remove and replace the brush box, you empower yourself as a DIYer, ensuring your drill remains in top condition for years to come.
Tools Required for the Job
Before you dive into the procedure, ensure you have the following tools at hand:
- Phillips screwdriver
- Flathead screwdriver
- Replacement brush box (if applicable)
- Multimeter (for testing)
Preparation: Safety First
Before beginning any kind of repair work, safety should be your top priority. Here are some essential safety guidelines to follow:
1. Disconnect Power
Ensure the drill is unplugged from any power source. If you have a battery-powered DeWalt D999, remove the battery. This step is critical to avoid any electrical hazards.
2. Wear Protective Gear
Put on safety goggles and gloves. Protecting your eyes and hands is essential, as small parts can fall and cause injury during the removal process.
Step-by-Step Guide to Removing the Brush Box from Your DeWalt D999 Drill
Follow these steps to safely and effectively remove the brush box from your DeWalt D999 drill:
Step 1: Locate the Brush Box
The brush box is usually located on the side of the drill’s motor. You may need to look for a small access panel or compartment.
Step 2: Remove the Screws
Using a Phillips screwdriver, carefully remove the screws that secure the brush box in place. There usually are two to three screws, depending on the model.
Tip: Place the screws in a small bowl or magnetic mat to prevent losing them during the process.
Step 3: Carefully Open the Brush Box
Once the screws are removed, gently pull or slide the brush box away from its housing. Be cautious not to use excessive force, as this could damage the surrounding components.
Step 4: Disconnect the Wires
Inside the brush box, you will see wires connected to the brushes. Carefully disconnect these wires. It may help to use a flathead screwdriver to gently pry them loose, but ensure you do this with caution.
Step 5: Remove the Brushes
Now that the brush box is free from the drill, gently pull out the carbon brushes. Inspect them for wear and tear. If they show significant signs of wear or damage, it’s time to replace them.
Inspecting the Brushes
After removing the brushes, take the time to inspect them thoroughly. A well-maintained brush will be smooth and not excessively worn down. Here’s what to look for:
- Length: The brushes should be sufficiently long to maintain contact with the commutator. If they are short, replace them.
- Condition: Look for cracks, chips, or discoloration, which indicates that they need replacing.
Replacing the Brush Box
Should you find that your brushes need replacing, follow these steps to install a new brush or a new brush box:
Step 1: Insert New Brushes
If you’re just replacing the brushes, gently slide the new brushes into their designated slots in the brush box. Make sure they fit securely.
Step 2: Reconnect the Wires
Reconnect the wires you previously disconnected, ensuring that they are attached firmly and that there are no frayed wire ends.
Step 3: Slide the Brush Box Back into Place
Align the brush box with the housing of the D999 drill and slide it back into place carefully.
Step 4: Secure with Screws
Using the Phillips screwdriver, reinsert and tighten the screws to secure the brush box. Be certain that they are snug but avoid overtightening, which could lead to damage.
Final Checks: Testing Your Drill
Once you have completed the installation, it’s essential to test the drill to ensure everything works correctly.
Step 1: Reattach the Battery
For battery-operated models, reinsert the battery. For corded models, plug the drill back into the power socket.
Step 2: Test the Drill
Turn on the drill to test its functionality. Check for smooth operation and listen for any unusual sounds. If all sounds normal and the drill works efficiently, congratulations! You’ve successfully removed and replaced the brush box.
Maintaining Your DeWalt D999 Drill
Once you are familiar with removing and replacing the brush box, it’s wise to understand the basic maintenance practices to extend the life of your drill.
Regular Inspections
Regularly inspect the drill for wear and tear. Look for damage to the casing, wires, and brushes.
Keep It Clean
Dust and debris can accumulate inside the motor housing, negatively affecting performance. Use a can of compressed air to blow out any buildup, keeping the drill clean and efficient.
Lubrication
Occasionally, spring mechanisms within the drill may need lubrication. Use a light machine oil and apply it sparingly to moving components.
Conclusion
In summary, removing the brush box from your DeWalt D999 drill is not only achievable but also a rewarding endeavor that enhances your DIY skills and tools management. By understanding how the brush box functions and knowing how to replace worn brushes, you can maintain the performance of your drill effectively.

What is a brush box and why is it important in the DeWalt D999 drill?
The brush box in a DeWalt D999 drill is a vital component that houses the carbon brushes, which transfer electrical current to the motor. These brushes are responsible for ensuring that the drill operates efficiently, providing the necessary power to the drill bit. When the brushes wear down, they can cause performance issues such as decreased torque, overheating, or even complete failure of the drill.
Maintaining the brush box is essential for the longevity of your drill. Regularly inspecting and replacing worn brushes can prevent further damage to the motor and enhance the overall performance of the tool. Understanding its function helps users appreciate the need for proper care and timely replacements.
How can I tell if the brush box needs to be replaced?
Signs that the brush box may need replacement include reduced power output, unusual noises, or a noticeable burning smell when using the drill. Additionally, if you find that the drill is sparking excessively or running inconsistently, these may indicate that the carbon brushes are worn down and not making proper contact with the motor.
It’s also wise to visually inspect the brush box during routine maintenance. If the brushes appear to be short, cracked, or damaged, it’s an indication that they need to be replaced to maintain optimal performance. Keeping an eye out for these signs can save you from costly repairs and downtime.
What tools do I need to remove the brush box from my DeWalt D999 drill?
To remove the brush box from a DeWalt D999 drill, you will need a few basic tools: a screwdriver (usually a Phillips head), a pair of pliers, and possibly a utility knife or wire cutters. The screwdriver will help you take off various screws securing the brush box, while pliers can assist in removing the wires if they are tightly attached.
Having a clean, organized workspace will make the task easier, and using a magnetic tray for screws can help you avoid losing any small components during the process. Before beginning the removal, ensure your drill is unplugged or the battery is removed for safety.
