i broke the wrench from the first break..thats when i decided to plug the hole. that does answer my question about that happening a lot though..Why else would testors make a tool for you to push a broken piece out unless they new that it was an issue..
I wish I thought about a drill bit when the fiirst one broke...at least I know now.
Thanks for the advice. I'll remeber it from now on.
I've already scrapped it for parts and tossed it now.
any suggestions on new brush? single/double?
thanks again
