There is a new blade on the Cold Cut Saw that has much larger and fewer teeth. Thank you Tim @tb for installing.
Got a piece of Mild Steel 2" square tube and did a test cut. Went through mild steel a lot faster with no apparent problem. Cut is just a little bit rougher, but not much. It is clean and left no burrs. So blade works fine.
WARNING: I would not cut thin flat stock in the vertical position as the blade is likely to catch on material and rip material or snap blade.
