Why do 6x48 belt sanders/grinders for metal seem …
I haven't tried the 2x72 knife style grinders, but they seem to remove a lot of material. Just spendy. I am on my third 6 x 48/12 sander/grinder since the first one around 1965. The current one is Japanese, bought new around 1990 for about $500, which was cheaper than the big Rockwell machines at the time.
