Compact replacement carbon brush designed for Fein angle grinders and polishers. Identified by Fein part number 30711154000, this is the original Fein carbon brush intended for use in 220–230 V (50/60 Hz) tool variants.

Key details:

- Carbon-block nominal dimensions: approximately 5 × 10 × 17 mm. The brush typically uses a pigtail/connection lug of roughly 23 mm.

- Intended electrical spec: for 220–230 V, 50/60 Hz Fein machines.

- Function: spring‑mounted carbon contact that presses against the commutator; replaces worn brushes to restore motor contact, reduce sparking and return normal performance.
