This is a common problem with sears tools. They make a tool for a specific time then change and quit making parts for it. My feeling about this is they do it because you will be forced to purchase something else. Way back when I bought a cordless drill from them after a couple years the battery charger quit and like you I was told they were no longer available so now I have a perfectly good drill, perfectly good batteries, just no way to charge them. Needless to say I quit buying craftsman power tools.
