Hey there! If your HILTI TE 15-C is acting up or making weird noises, it might be time for new carbon brushes. This set includes everything you need: two high-quality carbon brushes with automatic stop (so your tool shuts off before the brushes wear down completely), plus springs, cables, and connectors. Each brush measures 6.3x10x19mm (about 0.25x0.39x0.75 inches), and it's always a good idea to replace both at the same time for even wear. We specialize in carbon brushes, so ours actually last longer than many original parts. Shipping is simple and letterbox-friendly - no waiting around for delivery, though tracking isn't included to keep costs down. Got questions or need a custom size? We've got over 50,000 brushes in stock and a workshop ready to help. Keep your HILTI running smooth!
