316046800 - Metabo W9-115 Replacement Carbon Brush Set

Keep Your Metabo Grinder Running Strong

There is nothing more frustrating than being in the middle of a heavy grind or a critical cut and having your trusty angle grinder sputter and die. If your Metabo W9-115 has stopped working suddenly, or if you've noticed it losing power and sparking more than usual, don't throw it in the trash bin just yet. In most cases, the motor isn't dead—it just needs a fresh set of lungs. The Metabo 316046800 Carbon Brush Set is the exact replacement part you need to bring your tool back to life and get back to work.

Think of carbon brushes like the brake pads on your truck; they are designed to wear out so that the more expensive parts of the engine don't. These genuine Metabo brushes are built with a smart safety feature called "auto-stop." When the brush gets too short to work safely, it automatically cuts the power. This might feel like the tool died, but it's actually saving you money by stopping the metal spring from grinding into the motor's spinning core. If you use cheap knock-off brushes, you risk ruining the whole grinder. Sticking with the real deal ensures your tool lasts for years to come.

Installation is generally quick and can be done right at the workbench. You don't need to be a certified electrician to swap these out. Simply open the access covers on your grinder, pop out the old worn-down nubs, and slide these fresh brushes in. You'll feel the difference immediately—the motor will sound crisp, the torque will return, and you'll be back to grinding welds and cutting pipe with full power. This kit comes with both brushes you need for a complete swap.

We know that in the welding and fabrication world, time is money. A dead grinder means downtime. We recommend keeping a spare set of 316046800 brushes in your toolbox or shop locker. That way, when your grinder eventually hits that auto-stop limit, you can swap them out in ten minutes and finish the shift without skipping a beat. Invest in the maintenance of your tools, and they will take care of you on the toughest jobs.
