I'm getting ready to purchase a 6" or 8" bench grinder, mainly for quick sharpening of my HSS turning tools. I have a slow speed wheel (Delta) which I'll keep because it works pretty well for honing flatter work (chisels, etc). I'll probably outfit the grinder with the nice white Norton wheel and a Veritas tool rest.
Some of the units I've been considering have a dust collection port out the back. This is new to me. My concern is that those flying sparks of hot metal may not be compatible with the sawdust already in the shop vac or DC bags. Would I have to use a dedicated vac for the grinder? I wonder if it's really worth the trouble. The thought of hot metal particles in any bag just doesn't sit well with me.
My experience (as you can tell) with working metal is minimal, so any comment would be appreciated.
