Is your AEG SB2E720RX power tool starting to spark or lose power? It might be time for new carbon brushes. This set includes two replacement brushes specifically designed for the AEG SB2E720RX model (they replace original part number 4.931.392.605). Each brush measures 5x8x12.5mm and comes with a spring, cable, and connector for easy installation. They feature an automatic stop function – when the brush wears down to a certain point, it cuts power to protect your tool's motor from damage. These are made to last longer than the original brushes (since this is the seller's specialty), and they're shipped in a bubble mailer that fits through your letterbox so you don't have to wait around for delivery. Always replace both brushes at the same time for even wear. Keep your AEG tool running smoothly without the cost of a professional repair!
