As a general rule of thumb, your bench grinder will require the same kind of maintenance as any of your power tools do. Additionally, it will have one very special requirement, and that’s the wheel dressing. Wheel dressing is important to reduce wobble and to expose fresh grit so that you can continue to get the best results from your purchase. It’s always a good idea to routinely check your bench grinder and to ensure that it is always stowed away safely plus remove any dust and debris each time you’ve used your machine.\r
