Query: Works -- but not for long

This bit worked for less than two hours before the bearing broke off. I took it in to my bud at the lumber store to see if he had parts to possibly fix it, but he had another broken one sitting on his desk, that some other customer had returned because it broke after only a few hours. It started out cutting well, but it just doesn't hold up. If you only need it for very light use, it might be fine, but I can't recommend it.
