I guess I must be a slow learner because I tried it again and the same thing happened after cutting only a few inches, it wasn't cutting worth a darn anyway so I gave up and used a Milwaukee sawzall.
Anyone else have this happen? I meant to ask about this a couple of weeks ago when that happened but just never got around to it so when I saw this thread I thought I would mention it.
Actually I use the thin disk all the time for cutting aluminum but the disk I use are the Metabo brand. I also cut slow and if cutting steel or aluminum sheet, I first make a shallow cut on my line then go back over it until it's cut through.
