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.
