1. Basic Identification
Part Number: 10080346
Product Type: Carbon brush set (typically sold as a pair for balanced replacement)
Category: Motor power tool accessories (spare parts for electric motors in power tools)
2. Dimensions
Size Specification: 6.7mm (thickness) × 13mm (width) × 18.5mm (length)
Note: These precise measurements ensure compatibility with specific motor models, as brush slots in power tool motors are engineered to exact sizes.
3. Core Function
Transmits electrical current between the stationary part of the motor (stator) and the rotating part (rotor/commutator) in power tools.
Reduces friction while maintaining consistent contact during high-speed rotation, ensuring smooth motor operation.
4. Typical Applications
Designed for power tools with brushed motors, such as:
Angle grinders
Drills or impact drivers
Sanders or polishers
Other handheld electric power tools (compatibility depends on the motor’s brush slot dimensions).
5. Why a "Set"?
Sold as a pair to replace both brushes simultaneously, ensuring balanced pressure on the commutator.
Uneven replacement (e.g., changing one brush only) can cause uneven wear on the commutator, leading to motor damage.
6. Replacement Indicators
When the remaining length of the carbon brush is less than half of the original (≈9mm for this 18.5mm model).
Excessive sparking from the motor during use.
Reduced power or intermittent operation of the power tool.
7. Key Consideration
The part number (10080346) and dimensions (6.7×13×18.5mm) are critical for compatibility. Always cross-check with your power tool’s model number or user manual to ensure a proper fit.
