The MK Morse has worked out the best compared some of the other blades I've used. I've used about 10 of them so far. I generally cut 1/4" to 1/2" mild steel. I cut 2 by 2 tube with a 3/8" wall and it's no problem. I get a couple of hundred cuts before it becomes dull. I do not use it for rebar, however, because I've seen warnings about hitting hard spots. I also find that while it can cut 1" solid square stock, it's a little hard for it, so I use my abrasion saw.
I have been buying cheap blades for years
And then I thought I would try one made in
USA? Boy what a difference! Cuts so much
Better and last longer! Money well spent!
