Original Bosch brush holder — part no. 2609004170 — replacement brush-holder assembly designed to secure the carbon brush in the motor of compatible Bosch sanders.

This genuine Bosch item is listed for use in models such as the PEX 300 AE, PEX 400 AE and the PSM 200 AES (check the 10‑digit type number on your tool to confirm fit).

Sold as a single brush‑holder unit and shown on Bosch exploded parts diagrams and lists, it installs into the motor housing to hold the carbon brush in the correct position and make the electrical contact needed for the armature to run.

If your sander’s type number matches the models above, this original Bosch brush holder is the exact replacement called out in Bosch power tool parts diagrams.
