10080344 Power Tool Spare Parts: 6.3×16×25mm Carbon Brush Replacement
1. Product Identification
Part Number: 10080344 (likely a unique identifier for inventory, compatibility, or manufacturer reference)
Type: Carbon brush replacement (a consumable spare part for power tools)
Dimensions: 6.3mm (thickness) × 16mm (width) × 25mm (length) — precise sizing ensures fit for specific tool models
2. Core Purpose
A critical component in power tool motors, responsible for conducting electrical current between the stationary and rotating parts (e.g., commutator or slip ring) of the motor.
Enables the motor to convert electrical energy into mechanical motion, driving the tool’s functionality (drilling, grinding, cutting, etc.).
3. Compatibility
Designed for power tools (e.g., drills, angle grinders, impact wrenches) that require carbon brushes of this specific size (6.3×16×25mm).
The part number (10080344) helps confirm compatibility with particular tool models — always cross-check with the tool’s user manual or manufacturer specifications.
4. Material & Performance
Typically made from a graphite-copper composite (12–20% copper content) to balance:
Conductivity: Efficiently transmits electrical current.
Wear Resistance: Withstands friction against the commutator during high-speed rotation.
Expected service life: 50–100 hours of standard use (varies by tool load, speed, and operating conditions).
5. Replacement Indicators
When the remaining length of the carbon brush is less than half of the original (≈12.5mm for this 25mm model).
Excessive sparking from the motor during operation (signals poor contact).
Reduced tool power, intermittent operation, or unusual motor noise.
6. Installation Tips
Replace in pairs (if the tool uses two brushes) to ensure even pressure on the commutator, preventing uneven wear.
Clean the commutator with isopropyl alcohol before installing new brushes to remove carbon dust buildup.
Ensure the brush fits snugly in the holder without binding, as loose fit can cause arcing.
7. Key Note
Incorrect size or part number can lead to motor damage (e.g., commutator scoring, electrical shorts). Always verify compatibility with your power tool’s model before purchasing.
