I went today to pick up some cut off blades for my Makita die grinder. 1/4"
shaft. I found some larger 4" round discs, and some 3" ones. My Makita is
a 14,000 rpm unit. I have an air 25,000 unit.
I need to do some surgery on some wrought iron. Cut some pieces away that
have been MIG welded. I need nice controllable cuts, not like those you get
with regular 1/8" or so grinder wheels.
I couldn't find anything with a mandrel. And the sales geeks couldn't tell
me much about if they were fiberglass reinforced or not.
What am I looking for in name brand? Or size? Or mandrel? I think I need
fiberglass reinforcement so they don't fragment on me. I am going to cut
slowly, just so I can break the weld and separate the pieces, so won't be
bearing down a lot. I want something that won't blow up or turn to dust in
