What Are Carbon Brushes & Why Replace Them?
Carbon brushes are a critical wear component in brushed electric motors. They maintain the electrical connection between the stationary and rotating parts of the motor. Over time, brushes wear down through normal use, causing sparking, reduced performance, or motor failure. Replacing carbon brushes promptly extends the life of your tool and keeps it operating smoothly. For guidance on electrical safety when servicing power tools, visit the U.S. Consumer Product Safety Commission – Power Tools Safety.

Frequently Asked Questions
Q: What size are these carbon brushes and which tools are they compatible with?
A: These carbon brushes measure 10mm × 5mm × 5mm. They are designed to fit mini drills, small electric grinders, and other compact brushed electric motors that use brushes of this standard size. Always verify your tool's brush slot dimensions before installing.
Q: How do I know when my carbon brushes need to be replaced?
A: Common signs that carbon brushes need replacing include visible sparking near the motor, reduced tool power or speed, intermittent operation, or a burning smell. If the brush has worn down significantly shorter than the original length, it's time for a replacement.
Q: How do I install replacement carbon brushes in my mini drill or grinder?
A: First, ensure the tool is unplugged and powered off. Locate the brush caps on either side of the motor housing — these are usually accessible via a small slot or screw cap. Remove the worn brushes, insert the new carbon brushes with the spring side first, and replace the caps. Always consult your tool's manual for model-specific instructions.
