The disk is flat and quite thin. It looks to frail to cut steel, but walks right through it!
The cutting disc is designed for cutting stainless.
Maybe. But probably will basically burn through the wood. There are many better tools to make cuts similar to how this works in metal. Circular saws, wood blades for drills, multitools (very good) and dremel tools, jigsaws, table saws, hand saws.
