1 Pair Motor Carbon Brush Set (6.4×10×15mm) for DeWalt Electric Tool Parts

1. Product Identification

• Configuration: A set of 2 carbon brushes (1 pair), designed for balanced replacement in motor systems.

• Dimensions: 6.4mm (thickness) × 10mm (width) × 15mm (length) — precise measurements ensure compatibility with specific tool models.

• Application: Replacement parts for DeWalt (DW) electric tools, intended for motor current conduction.

2. Compatibility

• Brand Fit: Exclusively for DeWalt electric tools (e.g., drills, angle grinders, impact drivers) — verify with your tool’s model number or user manual.

• Motor Type: Suitable for brushed motors in DeWalt tools, where sliding contact with the commutator is required for operation.

3. Core Function

• Current Transmission: Conducts electrical current from the tool’s power source to the motor’s rotor windings via contact with the commutator.

• Wear Compensation: Designed as a consumable part, wearing gradually to protect the commutator from excessive damage during operation.

4. Material & Performance

• Composition: Typically made of graphite-copper composite (10–15% copper content) to balance conductivity and wear resistance.

• Wear Resistance: Rated for ~50–70 hours of standard use (varies by tool load and speed).

5. Replacement Indicators

• When the remaining length of the carbon brush is less than half of the original (≈7.5mm for this 15mm model).

• Excessive sparking from the motor during use.

• Reduced tool power, intermittent operation, or unusual noise.

6. Installation Note

• Replace both brushes in the set simultaneously to ensure even pressure on the commutator, preventing uneven wear.

• Clean the commutator surface with alcohol before installing new brushes to remove carbon dust buildup.

7. Key Consideration

• The dimensions (6.4×10×15mm) are critical for compatibility. Always cross-check with your DeWalt tool’s specifications to avoid improper fit, which can damage the motor.
