I'm going to make some speaker stands using Dexion Speedframe. It is 25mm square steel tube and will need many just ordinary right angle cuts. Obviously, the neater the better.
I have an angle grinder stand which turns a 4 1/2" one into a sort of chop saw. And an old B&Q 8" wood chop saw. Would the angle grinder give a decent cut using the appropriate disc? Is there a diamond or whatever one that would be best?
Or a metal cutting blade for the B&Q one? It's almost certainly an odd size. ;-)
