Replace Brush Set 6*10*20 MM Electric Tool Parts Carbon Brush

Carbon Brush Accessory Replace Brush Set 61020 MM Electric Tool Parts

Key Information Analysis:

1. Product Type: Carbon Brush Replace Set
   It usually contains 2 carbon brushes of the same specification, made by pressing a mixture of graphite and copper powder, with good electrical conductivity, wear resistance and high-temperature resistance. The set design facilitates the one-time replacement of carbon brushes on both sides of the motor, ensuring balanced current conduction and avoiding abnormal motor operation caused by uneven wear of carbon brushes on one side.
2. Compatibility Range:
   Based on the 6×10×20mm specification, it is suitable for brushed motors of various small and medium-sized electric tools. Common scenarios include:
   • Handheld electric tools: such as medium-sized electric drills, grinders, trimmers, small impact drills, etc.;
   • Portable equipment: some models of jigsaws, polishers, angle grinders (low-power models), etc.
     The core of compatibility is that the size of the carbon brush must completely match the brush holder of the electric tool motor (with an error of ≤0.2mm). Before replacement, check the length, width and height parameters of the original carbon brush to ensure consistent specifications.
3. Size Specifications: 6×10×20 MM
   This size belongs to the category of medium-sized carbon brushes. The length of 20mm can provide a longer service life (compared to small carbon brushes). The thickness of 6mm and width of 10mm are suitable for most standard 规格 brush holders. Dimensional accuracy directly affects the use effect; excessive errors may cause poor contact between the carbon brush and the commutator, leading to problems such as increased motor sparks and abnormal operation noise.
4. Functions and Roles:
   • As the "current conduction component" of the electric tool motor, it stably transmits external current to the rotor through close contact with the commutator, ensuring the normal start-up and operation of the tool;
   • The set replacement design ensures uniform wear of carbon brushes on both sides, maintains the balance of motor operation, and reduces equipment vibration or failures caused by excessive wear on one side.
5. Replacement Tips:
   The carbon brush set should be replaced in time when the electric tool shows the following situations:
   • The carbon brush is worn down to less than 1/3 of its original length (about 7mm);
   • There are significantly more sparks at the carbon brush during motor operation, or accompanied by a burning smell;
   • The output power of the tool decreases, it starts slowly or there is obvious stuttering during operation.
