Using the Bosch WBX318 cup brushes is easy. First, if you're using an X - Lock grinder, simply snap the X - Lock wheel onto the grinder. You'll hear an audible click to confirm it's properly attached. There's no need for tools like a spanner wrench or flange nuts. When you're done and want to change the wheel, just pull the lever on the grinder. These brushes are great for removing weld scale, burrs, and corrosion on metal surfaces. When using them with a small angle grinder, hold the grinder firmly and move it smoothly over the surface. As for maintenance, after each use, clean the brush to remove any debris. Store it in a dry place to prevent rusting. Always make sure the grinder is turned off and unplugged before attaching or detaching the brush.
