I must have gotten a good unit then. I have beat the ******** out of it for years. Ported multiple engines with it. :dunno:
I have given up on dremels. I get almost no use out of the thing before it breaks. Its not like I am using the thing like a hammer either. They just are not intended for serious cutting, grinding or the like. If I grind - air die grinder. If I cut - 4" angle grinder with cutoff wheel.
I firmy beleive that Dremels are intended for socker moms to sand the spindles on their shaker - style kitchen chairs. That was reinforced when they came out with a rechargeable.
Now the full size roto-zip tool is another story that thing can make some dust and lasts too.
