Daves,
I only use the Dremel cutoff when it's absolutely necessary. I also have
some diamond wheels that come in handy from time to time.
The rest of the time, (whenever it will fit), I use the big angle grinder.
For most of my sheetmetal work I have a 3/64 cutoff wheel. When there's
big stuff I switch to the 1/8" cutoff wheel. The thick wheel has the
fiber reinforcement whereas the thin one doesn't. I burn through a thin
wheel in a couple of days when going full steam. I imagine that a full
time shop would buy them bulk, I burned out one in one session once (4
feet of cutting, and I went a bit too fast... those wheels really stink
when they burn!!)
The dremel is great for fiddly things but I would leave it alone for
anything bigger than 1/4" (unless you're REALLY patient)
