what is the comparative hardness of metals?
Cold rolled steel is only "5" on the Moh's scale. Copper is a lot softer. But what is the hardness ?
Brass is 3.5 and glass is 5.5, harder than CRS.
Stainless steel must be a lot softer than CRS, and cutting it may be closer to cutting copper than CRS.
Just brain storming.
On the other hand, i was trying to grind through a 5/8 square lathe tool bit, cut it in half on a cut-off saw (grinding disk) and could not get through it.
On the Moh's scale talcum is 1 and diamond is 10.
