Fein 30711129009 — genuine Fein carbon motor brush for MultiMaster / MultiTalent oscillating tools; a direct replacement carbon brush that restores reliable commutator contact and electric braking.

Fits many Fein oscillating models including FMM 250 and FMM 250 Q (MM250Q), FMT 250 (and Q/SL variants), MSx 636 II / MSxe 636 II and similar MultiMaster tools.

Sold individually (order two for a complete repair) — the brush is a small rectangular carbon block (approx. 5 × 8 × 12 mm) with the spring/lead arrangement used in Fein brush holders; replacing both brushes is the typical remedy for intermittent motor operation or loss of power.

Easy to fit: this original Fein brush slips into the holder, is retained by the brush spring and lead, and is a commonly replaced wear item among power tool parts — swapping both brushes and checking the commutator will often bring a tired tool back to normal.
