Overview

Ensure the longevity and peak performance of your power tools with these high-quality carbon motor brushes. This product is a pair of replacement carbon brushes, specifically the CB-43 model, designed to fit a variety of power tools. Measuring 17mm x 11mm x 7mm, these brushes are essential components for transmitting electrical current to the motor’s rotating commutator. Over time, carbon brushes wear down, leading to reduced motor efficiency or complete failure. Replacing them with a new set of CB-43 brushes can significantly extend the life of your equipment and maintain consistent power delivery. These brushes are a crucial maintenance item for any enthusiast or professional looking to keep their tools in top working order.

Crafted for durability and optimal conductivity, these carbon motor brushes provide a reliable solution for worn-out originals. They are a cost-effective way to revitalize your power tools without the need for expensive new equipment. Each brush is engineered to meet standard specifications, ensuring a snug fit and effective operation. Whether you’re working on a DIY project or professional tasks, having spare or replacement power tool brushes on hand is always a smart choice.

Key Benefits

Investing in new carbon motor brushes offers several advantages, ensuring your power tools operate at their best:

• Restored Motor Performance: Worn brushes can cause intermittent power, sparking, or complete motor failure. Replacing them with fresh carbon motor brushes restores full power and smooth operation, making your tools feel like new.
• Extended Tool Lifespan: Regular replacement of components like these CB-43 brushes prevents further damage to the motor and other internal parts, significantly extending the overall lifespan of your valuable power tools.
• Cost-Effective Maintenance: Rather than purchasing a brand new power tool, replacing just the power tool brushes is a much more economical solution for common motor issues, saving you money and resources.
• Improved Efficiency: New brushes ensure optimal electrical contact, leading to more efficient power transmission and less energy wastage, which can translate to better performance and longer battery life for cordless tools.
• Reduced Sparking: Worn brushes often cause excessive sparking, which can be dangerous and indicates poor electrical contact. Fresh 17mm carbon brushes reduce sparking, leading to safer and more stable operation.
• Easy to Install: Designed for straightforward replacement, these motor brushes can often be installed with basic tools, making it a convenient DIY repair for many users.
• Versatile Compatibility: While specific to the CB-43 model, these brushes are a common size for various power tool brands and types, making them a versatile motor replacement parts option.

Maintenance & Installation Tips

Replacing your carbon motor brushes is a relatively simple process that can significantly improve your tool’s performance. First, always ensure the power tool is unplugged or the battery is removed to prevent accidental startup. Locate the brush caps on the sides of the motor housing; these are usually screw-on or clip-on. Carefully remove the old brushes, noting their orientation. When installing the new CB-43 brushes, make sure they slide in smoothly and are seated correctly. Do not force them. Once in place, replace the brush caps securely.

It’s generally recommended to replace both power tool brushes at the same time, even if only one appears worn, as they tend to wear at similar rates. After installation, run the tool without a load for a minute or two to allow the new brushes to seat properly against the commutator. This ‘bedding-in’ period helps ensure optimal contact and performance. Regular inspection of your 17mm carbon brushes can help you identify wear before it leads to serious motor problems.
