1. Product Overview
Replacement carbon brushes for Bosch TE1, TE5, TE10 hammer drill models.
Essential wear parts for maintaining motor conductivity in impact drilling tools.
2. Compatibility
Applicable Models:
TE1 (1-26mm drill), TE5 (1-28mm), TE10 (1-32mm)
Function: Transmit current to rotor windings via commutator contact under impact loads.
3. Technical Specifications
Dimensions:
Thickness: 8mm × Width: 12mm × Length: 20mm (standard for TE series)
Material: Graphite-copper composite (20% Cu content) for high conductivity.
Wear Rate: <0.15mm/100 hours under normal operation (1,500-2,800 RPM).
4. Replacement Indicators
Carbon brush length < 10mm (50% wear of original 20mm).
Abnormal sparking, reduced impact force, or motor overheating.
Visible grooves on commutator surface (>0.4mm depth).
5. Installation Steps
Disconnect power and remove rear motor cover.
Extract old brushes and springs (note spring tension direction).
Clean commutator with alcohol, remove carbon dust deposits.
Install new brushes, ensuring arc surface matches commutator curvature.
Verify spring pressure (1.8-2.2kg using a force gauge).
6. Maintenance Tips
Inspect brushes every 30 hours of use (or 500 impact cycles).
Replace brushes and springs as a set to maintain uniform pressure.
Avoid using worn brushes to prevent irreversible commutator damage.
7. Purchase Notes
Confirm part number (e.g., Bosch 1600860250) matches tool manual.
Aftermarket options should specify "for TE1/TE5/TE10" compatibility.
Store in anti-static packaging to protect conductive material.
