Set of two carbon brushes for electric motor 5x8x12mm - Reliable spare part for your power tools
Looking for an efficient, fast and affordable way to restore the original power and high rpm of your favorite angle grinder, impact drill, router or other power tool? The set of two carbon brushes for electric motors measuring 5x8x12mm (SKU: G00471) is the ideal solution for a quick, safe and easy home or professional repair. As a key consumable for electric motors, these graphite brushes ensure a smooth, constant and safe transfer of electric current to the moving parts of the motor, allowing your machines to operate stably without interruption.
Every power tool wears out over time with regular use, and carbon brushes are among the most stressed and exposed components in any motor. When brushes wear below a critical limit, problems such as excessive sparking, power fluctuations under load, or the tool not starting at all inevitably occur. By replacing worn brushes with our high-quality replacement set, you will effectively extend the life of your devices, restore their original performance, and avoid unnecessary and expensive purchases of new tools or visits to expensive service centers.
Why choose our 5x8x12mm carbon brush set?
Our set of two carbon brushes has been carefully designed with long-lasting performance, maximum conductivity and optimal protection of the vital parts of your tool in mind. They are made from a premium, precisely measured blend of carbon and graphite, which brings a number of technical advantages over standard, cheaper and harder substitutes on the market. The main and most important advantage of these brushes is that they do not increase commutator wear, which is a key factor in maintaining the long-term health of the entire electric motor.
Thanks to their extremely precise industrial manufacturing and standard dimensions of 5x8x12mm, these brushes fit perfectly and without jamming on various models and brands of power tools. Whether you are a professional craftsman who needs a reliable tool every day or a passionate DIYer, this set will become an indispensable part of your spare parts stock in the workshop.

How to recognize when it is time to change the carbon brushes?
Electric motors often let us know when they need maintenance and replacement of consumable parts with certain signs. Pay attention to the following three most common symptoms that clearly indicate that your brushes are worn out and need immediate replacement:

Strong and unusual sparking in the motor: If you notice strong blue, red or yellow light (sparks) through the ventilation slots of your tool's housing, the brushes are probably too worn or the spring pressure is weakened.
Erratic operation, speed fluctuations or shutdown: The tool suddenly loses power while working, stops randomly or only works when held at a certain angle or shaken.
The tool no longer starts at all: When the graphite brushes are completely worn out and lose contact with the commutator, the electrical circuit is interrupted and the motor can no longer start.

If you notice any of these symptoms on your tool, stop working immediately, check the physical condition of the brushes and replace them if necessary with our new set G00471 to prevent permanent damage to the motor.
Frequently Asked Questions and Answers (FAQ)
How do I know if these brushes fit my power tool?
The most reliable and safe way is to carefully remove the used brushes from the housing of your tool and measure them accurately with a caliper. If the dimensions of your old brushes (or the metal guide/housing itself) are approximately 5 mm (thickness) x 8 mm (width) x 12 mm (length), then this set is the perfect and appropriate choice for you.
Can I use these brushes with tools from different brands?
Yes, of course! Carbon brushes are a universal consumable used in almost all types of brushed electric motors. When choosing, the brand of the tool itself (e.g. Bosch, Makita, DeWalt, Black&Decker, etc.) does not play a role. The key is that the dimensions (5x8x12mm) and shape match the specifications and space in your motor perfectly.
Why is it important that brushes do not increase commutator wear?
The commutator is the rotating copper part of the rotor, on which carbon brushes continuously slide under spring pressure. If replacement brushes are made of too hard, untested or poor quality material, they act as an abrasive and can quickly damage or deeply "bind" the softer copper on the commutator. This causes the rotor to be destroyed and leads to irreparable damage to the entire motor. Our high-quality graphite brushes are optimized with a softer structure, which ensures excellent conductivity with minimal friction and maximum protection of the commutator.
