Old Eaton tools can be surprisingly durable, especially if they’ve been stored properly. My grandfather’s impact wrench is over 40 years old, and it’s still one of the most reliable tools in my garage. The only tricky part is knowing the exact model, because Eaton made small design changes over the years that can affect which parts you need. Sometimes the model number is hidden under layers of dust or worn-off paint, so I always recommend giving the tool a good clean first. That alone can make your search for the right information a lot easier.
