Fein 30711140000 Spare Part - Carbon brush

Fein carbon brush — part number 30711140000. Direct replacement motor carbon (graphite) used in Fein brushed motors to restore reliable contact with the commutator when your tool has stopped running or is sparking. This is the same Fein part number found in Fein parts lists and specialist spares catalogs.

Key details:

- Carbon block visible dimensions: approximately 5 × 8 × 13–14 mm.

- Insulated stranded copper lead with a flat crimp terminal (suppliers list terminal widths in the ~3 × 5–7 mm range) and an automatic cut-off/autostop feature on the brush lead.

- Typically sold as a pair (two brushes).

These physical specs let you compare the replacement directly with the worn brush in your tool to confirm fit.

Example Fein models this part is listed as fitting (use these as a compatibility check, compare the brush shape/measurements before installing):

- Fein AS TL 638 / AS TLXE 638 and AS TLXE 639.

- Fein FSN 400 and FSN 404 E.

- Fein KBM 32 (KBM 32 Q).

- Fein WSS 6.5‑115.

These model matches are taken from Fein parts listings and multiple spare-parts suppliers; verify against the brush in your machine to be certain.

Why this part matters: replacing worn carbon brushes with the correct Fein part number restores motor performance, reduces arcing, and prevents further damage to the commutator. When replacing, swap both brushes at the same time, confirm the lead/terminal orientation matches your brush holder, and observe the autostop connection arrangement shown on your old brushes.
