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.
