Dremel 4000 repair...

Check out Dewalt on St James. They usually carry most brands. Also Athena on Empress ( not sure if they carry it but will order for you). Switch is usually the culprit as they are always low quality. The bearings also don't last very long in these if you abuse it too much so if there is a large amount of play order bearings as well.

Thanks Bill,but i went to home Depot where I bought it and they told me to bring it back for exchange,it's only about 5-6 months old,I think.8)
