Function: Worn carbon brushes that restore motor power are the main reason motors work intermittently, brakes lose strength, and power drops. Replacing them can bring your motor back to full power, stable performance, and longer tool life. Durable Materials: Made from graphite and copper, these carbon brushes offer excellent conductivity, stable performance, and longer durability, ensuring your power tools and motors run at their best. Applications: Carbon brushes are widely used in various power tools and motors, such as circular saws, cutting saws, electric drills, hammer drills, vacuum cleaners, motorcycles, fan motors, cutting machines, angle grinders, and more. Note: Carbon brushes are the most commonly replaced parts in power tools. As wear parts, they gradually wear down with friction and usage and eventually need replacement. Worn carbon brushes often cause motors to run intermittently, reduce braking performance, and weaken motor power… 50PCS 4.5* 6.5 *20mm Motor Carbon Brushes Regulator Carbon Direct installation, Manufacturer: jianhuashanghang
