Carbon Brush Holder Electric Hammer Drill GBM500RE Power Tool Spare Parts

Power Tool Spare Parts: Electric Hammer Drill GBM500RE Carbon Brush Holder

This is a power tool spare part, specifically a carbon brush holder designed for the Bosch GBM500RE electric drill—a key structural component in the tool’s motor system.

Key Details:

1. Product Type: Carbon Brush Holder
   The core function of the carbon brush holder is to secure the position of carbon brushes, ensuring stable contact between the brushes and the motor’s commutator. It also provides continuous pressure to the carbon brushes via a built-in spring (in some models) to compensate for wear during use, facilitating smooth current conduction from the power source to the motor’s rotor and driving the tool’s operation.

2. Compatibility: Bosch GBM500RE Electric Drill
   The GBM500RE is a classic electric drill by Bosch (referred to as an "impact drill" in some regions), typically with a power rating of around 500W. It is used for drilling and screw-driving tasks in home renovation and light industrial settings. This carbon brush holder is exclusively engineered for its motor, with dimensions and structure perfectly matching the internal space of the motor.

3. Function and Importance:

• Prevents carbon brushes from shifting or falling off due to tool vibration, ensuring stable current conduction.

• Protects internal motor components by reducing contamination from carbon dust generated by brush wear.

• Extends the service life of both the carbon brushes and the motor, maintaining the tool’s power output and operational stability.

4. Replacement Needs:
   Replacement is required when the original brush holder is damaged (e.g., cracked, deformed, or with a broken spring), as this causes poor contact of the carbon brushes. Symptoms include reduced drill power, abnormal motor noise, or excessive sparking. Timely replacement of the brush holder prevents further motor damage and restores the tool’s normal performance.

In summary, this is a dedicated carbon brush holder spare part for the Bosch GBM500RE electric drill, critical for ensuring normal motor operation and extending the tool’s service life.
