This is a power tool accessory, specifically a carbon brush with the model MK CB153—a key consumable component in power tool motors.
Product Type: Carbon Brush
Made of conductive materials like graphite, carbon brushes are core components in the motors of power tools (such as angle grinders, electric drills, and grinders). Their role is to conduct electrical current from the power source to the motor’s rotating rotor (via contact with the commutator), driving the motor to operate and enabling the tool’s functions (e.g., drilling, grinding).
Model Identification: MK CB153
"MK" may be an abbreviation for a brand or series code, while "CB153" is the specific model of the carbon brush. This model number distinguishes products of different sizes and specifications, ensuring compatibility with specific power tool models.
Compatibility:
Designed exclusively for power tools that require the MK CB153 carbon brush. The exact tools it fits (e.g., specific brands or models of electric drills, angle grinders, or cutters) should be checked against the tool’s manual or manufacturer’s instructions.
Function and Replacement Needs:
Carbon brushes gradually wear down due to friction with the commutator during use, making them consumable items.
Replacement is necessary when the brush is worn to about half its original length, or when the motor produces excessive sparking, the tool loses power, or operates with abnormal noise. This prevents motor damage and maintains tool performance.
In summary, this is a power tool-specific carbon brush with the model MK CB153—an essential accessory for ensuring normal motor operation and extending the tool’s service life.
