Carbon Brush for 10080467 Power Tool Spare Parts Electric 5*8*15.5mm Replace Motor Brushes

I. Basic Information and Core Parameters

• Product Code: 10080467

• Dimension Specifications:

• Thickness: 5mm × Width: 8mm × Length: 15.5mm

• Compact size suitable for carbon brush slots in small power tool motors.

• Core Attribute:

• Dedicated replacement carbon brush for power tools, used for motor current conduction as a wear-and-tear component.

II. Compatible Equipment and Model Details

• Applicable Tool Types:

• Suitable for small power tools such as drills, angle grinders, and rotary hammers, commonly found in 550–750W models from brands like Bosch and DeWalt (e.g., Bosch TSB1300 drill).

• Compatibility Logic:

• Designed for medium-low speed operations (suitable for 3,000–8,000 RPM), with spring pressure ranging 1.2–1.6kg, adapted for light-load tasks like daily drilling and grinding.

III. Technical Parameters and Working Mechanism

1. Material Characteristics:

• Made of carbon-graphite composite with 10–15% copper powder, featuring conductivity up to 10⁻⁵Ω·m and wear coefficient <0.1mm/100h, balancing conductivity and wear resistance.

2. Current Conduction Principle:

• Maintains sliding contact with the commutator via spring pressure to transmit current to rotor windings, driving tool operation (e.g., 5,000 RPM for a 650W drill).

3. Wear Replacement Thresholds:

• Replace immediately when remaining length is less than 1/2 of the original, or when abnormal sparking or reduced tool power occurs to prevent motor jamming due to commutator wear.

IV. Installation and Maintenance Guidelines

• Installation Steps:

1. Power off and remove the tool's rear cover; extract the old carbon brush and spring.

2. Clean the commutator surface with alcohol to remove carbon powder, and inspect for minor scratches.

3. Polish the new carbon brush arc with sandpaper to fit the commutator, and secure the spring in the fixing slot (replace the spring if pressure is insufficient).

• Maintenance Recommendations:

• Inspect wear every 30–40 hours of use. When replacing carbon brushes, clean internal motor carbon powder to prevent heat dissipation issues from dust accumulation.

V. Comparison with Other Carbon Brushes

VI. Purchase and Replacement Recommendations

• Specification Verification:

• Beyond dimensions, confirm current-carrying capacity (8–10A) and compatible voltage (220V/110V), and note voltage compatibility for imported models.

• Professional Tips:

• If the tool has difficulty starting or unstable speed, the carbon brush may be worn or the spring failed. Replace the entire carbon brush assembly (including the spring) and check commutator wear depth (grind for repair if exceeding 0.3mm).
