The SMD is an armored diamond which is usually used for carbide and steel
          applications in a 50/50 ratio. The 110 grit is on the course end of the
          spectrum for a super abrasive and should give a finish of around 32RA. This
          wheel has an R grade resin. This wheel was purchased with a machine and is
          still in it's original factory crate.
