I have a bunch of old tool steel. I would like to know what some pieces are, and what they would be used for.
- I have REX MM which I cannot find info on.
- REX AAA I found was : Rex AAA combines high red hardness, moderate abrasion resistance, and good toughness. This grade is frequently used for more severe cutting applications than M2, such as machining stainless steels. Rex AAA makes an outstanding tool bit for general purpose applications.
- I have something that looks like Super M I think super mo-max, but it's not shinny like my other mox max. including a pic.
