Overview
Keep your favorite electric power tools running smoothly and efficiently with these high-quality carbon motor brushes. This listing is for a single pair of durable brushes, each precisely measured at 18mm x 17mm x 7mm. Carbon brushes are a critical component in many electric motors, responsible for conducting current between the stationary and rotating parts of the motor. Over time, these brushes wear down, leading to reduced performance or complete motor failure. Replacing them promptly with a new set of power tool brushes can significantly extend the lifespan of your equipment and restore its original power and reliability. These are essential replacement motor brushes for a variety of general power tool applications, ensuring consistent electrical contact and preventing damage to your motor’s commutator.
Key Benefits
Investing in quality replacement parts like these carbon brushes offers numerous advantages for your power tools and your projects:
- Restored Performance: Worn brushes can cause intermittent power, sparking, or complete failure. Installing new carbon motor brushes helps restore your tool’s original operating efficiency and power, ensuring smooth and consistent operation for any task.
- Extended Tool Lifespan: Regular replacement of worn brushes prevents further damage to the motor commutator, which can be costly to repair or replace. These electric motor brushes act as a sacrificial part, protecting the more expensive components of your tool.
- Cost-Effective Repair: Instead of buying a new power tool, simply replacing the carbon brushes is a much more economical solution, saving you money while maintaining your existing equipment. This makes them a smart choice for maintaining your toolkit.
- Reduced Sparking: Worn brushes often lead to excessive sparking, which can be dangerous and indicates poor electrical contact. Fresh brushes minimize sparking, promoting safer operation and more stable current flow.
- Easy Maintenance: Carbon brushes are generally straightforward to replace, making them an accessible maintenance task for most DIY enthusiasts and professionals. This pair of 18x17x7mm carbon brushes is designed for easy installation.
- Universal Application: Designed for general use, these brushes are suitable for a wide range of power tools that utilize brushes of this specific dimension, including drills, grinders, saws, and more.
Tool Maintenance & Installation Tips
Maintaining your power tools by regularly checking and replacing components like electric motor brushes is crucial for longevity and performance. When installing these replacement motor brushes, always ensure the power tool is disconnected from the power source to prevent accidental startup or electrical shock. Locate the brush caps, usually on the sides of the motor housing, and unscrew or unclip them. Carefully remove the old, worn brushes and note their orientation. Insert the new carbon motor brushes, ensuring they slide smoothly into their holders and make proper contact with the commutator. Reattach the brush caps securely. After installation, it’s recommended to run the tool at a low speed for a minute or two to allow the new brushes to seat properly. If you’re unsure about the process, consult your tool’s manual or seek professional assistance.
