Got a power tool—like a circular saw, miter saw, or other electric motor—that's acting up? Maybe it's sparking, running intermittently, or the electric brake isn't working right? Worn-out carbon brushes are a common culprit. This uxcell set gives you 10 pairs (that's 20 individual brushes) of replacement carbon brushes. Each brush measures 13.6mm long, 5.8mm wide, and 4mm thick. They come with wire leads and brush springs already attached, so they're ready to install. Replacing old, worn brushes can often restore smooth operation, fix intermittent power issues, and bring back proper electric braking in tools that have it. The brushes are made from quality carbon material designed to handle the electrical contact in motor commutators. Installation varies by tool—usually you need to access the brush holders, remove the old brushes, and slot these new ones in. Make sure to disconnect power before working on any tool! This pack is great if you're a DIYer who fixes tools often, or if you have multiple tools that use similar-sized brushes. Having spares on hand saves time when a tool suddenly quits. A practical, affordable maintenance part for keeping your workshop running.
