Handy with tools? This 20-piece carbon brush set is a lifesaver for fixing all sorts of electric motors in power tools, appliances, and more. Each brush measures 6mm x 10mm x 15mm, a common size for many devices. Carbon brushes are those little conductive blocks that wear down over time – when they get too short, your tool might run poorly, spark, or stop working altogether. Replacing them is often a much cheaper fix than buying a new tool. This set gives you plenty of spares. The brushes are heat-treated for durability and good conductivity. Just make sure to check the size of your old brushes before ordering to ensure they match. A must-have for any DIYer, hobbyist, or repair technician's toolbox. Keep your gear running smoothly and save money on repairs!
