Role of carbon brushes: Motor carbon brushes provide reliable switching and current collection performance, designed for replacement and routine maintenance. Carbon brush wear is a common cause of intermittent motor performance issues, including reduced braking efficiency and diminished motor power. Robust and durable: These replacement carbon brushes are made of high-quality graphite metal, offering high hardness, excellent wear resistance, corrosion resistance, low sparking, low noise, and extended service life. Carbon brushes are among the most commonly used components in power tools. Carbon brush replacement: Replacing worn carbon brushes helps maintain optimal motor performance and prevents operational interruptions due to poor electrical contact. Proper replacement can resolve issues such as unexpected motor shutdowns and restore electric brake functionality. Wide range of applications: Suitable for use in electric circular saws, miter saws, electric drills, hammer drills, dust extractors, motorcycles, weeders, blowers, cutting saws, angle grinders, and other appropriately sized power tools and electric motors. Package includes: 20 carbon brushes, each measuring 5x5x10mm, providing a sufficient supply for timely replacements. Carbon brushes are essential components in electric grinders; without them, motors cannot operate properly. Replace the carbon brushes instead of the entire motor to restore function. This is one of the most frequently replaced power tool parts. Features: 1. High hardness, resistant to wear, durable, corrosion-resistant, long service life 2.
