Set of two carbon brushes for electric motors 7x11x16mm - Top quality for a long service life of your tool
Are you looking for a reliable and high-quality replacement part that will restore your power tool to its original power and extend its lifespan? The set of two carbon brushes for electric motors, dimensions 7x11x16mm (SKU: G00478) is the ideal solution for professionals and DIYers who demand flawless performance from their tools.
Carbon brushes (also called graphite brushes) are one of the key consumable parts of every electric motor. They ensure the smooth transmission of electric current to the rotating part of the motor (commutator). Choosing quality brushes is crucial, as poor-quality materials quickly damage the motor, leading to expensive repairs or even the purchase of a new tool. Our set of two graphite brushes ensures optimal conductivity and minimal friction.
Why choose our carbon brush set for electric motors?
The main advantage of these brushes is their advanced composition of high-quality graphite. They are designed to wear evenly during operation and do not increase commutator wear. This means that your electric motor will run quieter, contact search will be minimal, and the life of the rotor itself will be significantly longer.
Replacing worn brushes is a simple and extremely cost-effective way to maintain your tools. Instead of buying a new machine, you can restore the performance of your favorite drill, grinder or other power tool with a minimum investment of €6.99.
Key features and technical data

Precise dimensions: Width 7 mm, thickness 11 mm and length (height) 16 mm – ensuring a perfect fit in the corresponding brush slots.
Premium material: High-quality carbon (carbon - graphite), which provides excellent electrical conductivity and resistance to high temperatures.
Motor protection: Special composition prevents excessive friction and does not increase wear on the sensitive copper commutator.
Set: The package contains 2 pieces (pair), which is sufficient for a complete replacement on one electric motor.
Versatile use: Suitable for various types of power tools and machines that use brushes of these dimensions.

Benefits of using quality graphite brushes
When carbon brushes wear out, you may notice a drop in motor power, sparking inside the housing, or the tool may not start at all. By replacing them with our 7x11x16mm set, you will receive the following benefits:

Full power restoration: Your tool will work again with full power and optimal speed.
Stable operation: No interruptions in operation due to poor contact on the commutator.
Save money: Preventive brush replacement prevents serious damage to the motor that would require expensive repairs.
Less arcing: High-quality graphite reduces arcing (sparking), which protects the tool's internal components from overheating.

How to recognize when it's time to replace your brushes?
We recommend that you check the condition of your brushes if you notice any of the following signs:

The tool emits strong sparks through the ventilation slots during operation.
The motor operates intermittently (turns off and on again when you move the cable or tool).
The tool has completely stopped working, even though it is connected to the mains.
You detect a smell of gunk or overheating during operation.

Installation instructions
Before starting the replacement, always make sure that the power tool is disconnected from the mains or that the battery is removed. Open the brush holder covers on the motor housing, remove the old, worn brushes and clean the holder of any graphite dust. Insert the new brushes from the kit and firmly replace the covers. After replacement, we recommend that the tool be operated without load (idle) for a few minutes so that the new brushes can run in properly and adapt to the shape of the commutator.
Frequently Asked Questions (FAQ)
1. How do I know if these brushes fit my power tool?
The most reliable way is to remove the existing worn brushes from your tool and measure them with a caliper. If the dimensions of your old brushes are approximately 7x11x16mm (minor variations due to wear are normal), then this set will fit your tool perfectly.
2. Does the set contain one or two brushes?
The set contains 2 pieces (one pair) of carbon brushes. Since brushes in electric motors always wear out in pairs, it is essential to replace both brushes at the same time, which this set allows you to do.
3. Can these brushes damage the commutator of my motor?
No. Our carbon brushes are made of soft yet durable high-quality graphite, which is specifically designed to place minimal stress on the copper on the commutator and not cause premature wear.

Answers to frequently asked questions

How do I know if these carbon brushes are compatible with my electric motor?

Are these brushes suitable for professional use?

The set is intended primarily for home and occasional repairs. For heavily loaded or professional tools, original or reinforced spare parts are recommended, where durability and service life play a greater role.

What to do if the tool still does not work properly after assembly?

If the tool still does not work optimally after replacing the brushes, we recommend that you also check for other possible causes, such as a worn commutator, damaged wires or connections. If necessary, consult a specialist or repairer.

Can I use these brushes with different brands of tools?

If the brush dimensions are suitable and the connection method allows installation, these brushes can be used with different brands, but always check the manufacturer's instructions or consult the seller.

What is the recommended procedure for replacing carbon brushes?

Before replacing, disconnect the tool from the power supply, then remove the holder with the old brushes and carefully replace them with new ones. After installation, we recommend a short test run and a few minutes of low speed start-up to allow the brushes to adapt to the collector surface.
