Bosch 1617014122 — genuine Bosch carbon-brush set for rotary hammers and demolition hammers. Perfect if your Bosch hammer is sparking, losing power, or has hit the service indicator — this set restores reliable commutation and motor performance.

Key details: two carbon brushes (pair) manufactured to Bosch tolerances; nominal dimensions ≈ 6.3 × 12.5 × 22 mm (check orientation for your holder). Many listings note these brushes include the wear cut-off/auto‑stop contact used on models that support that safety feature.

Typical compatible Bosch tools (examples): GBH 5/40 DCE (GBH 5 DCE), GBH 5 series, GBH 38, GSH 4 / GSH 5 CE and various GBH 7 series hammers — confirm the part number on your tool’s spare‑parts list or the label before fitting.

Fit notes: this is the brush set listed in Bosch power tool parts diagrams for the GBH/ GSH (part 1617014122 / 1 617 014 122). If your tool’s brush size or holder differs, the stated dimensions will help verify fit.

Easy to install: replace the worn brushes with the motor de‑energized, insert the brushes into their holders and reassemble — this restores clean contact and quieter operation for these older Bosch hammers.
