What this product is Carbon brushes (Kohlebürsten) made from durable carbon materials for use in electric motors and power tools. Why you need them Replace worn brushes to prevent loss of power, sparking, motor overheating, or complete motor failure. Regular replacement restores smooth motor operation and reliable tool performance. Key benefits Durable construction: built to resist wear from friction and prolonged use. Reliable performance: helps maintain motor torque, electrical contact, and consistent operation. Easy maintenance item: a common, essential spare part that extends the life of your tools. Function and performance Provide the electrical contact between the stationary and rotating parts of the motor. Smoothly transfer current while minimizing sparking and wear when in good condition. Timely replacement of these brushes keeps motors running within designed specifications. Compatibility Widely compatible with many electric tools and motors, including circular saws, miter saws, electric drills, hammer drills, vacuum cleaners, motorcycles, fan motors, cutoff saws, angle grinders, and similar equipment. Always check the brush shape and dimensions against your tool’s original part to ensure a correct fit. Material and construction Made of carbon-based brush material designed for electrical conductivity and wear resistance. Constructed to withstand heat and friction typical in power-tool motor environments. Practical applications (use scenarios) 1. Circular saw: Swap in new brushes to restore cutting power and reduce motor sparking after heavy use on construction or workshop projects. 2. Vacuum cleaner or fan motor: Replace aged brushes to recover suction or airflow performance and reduce noise from intermittent contact. 3. Angle grinder or cutoff saw: Fit fresh brushes before demanding grinding or cutting tasks to maintain steady RPM and prevent sudden power loss. Installation and maintenance tips Replace brushes in pairs when possible to ensure even wear. Inspect commutator and brush holders for damage or debris during replacement. If you are unsure about fit, compare the dimensions and connector type to your original brushes before installation. What to expect A straightforward replacement part that restores motor efficiency, reduces the risk of further motor damage, and helps keep your power tools operating reliably.
