10% grade with a 0.5 grain size used for milling hard material in the 45-70HRC range, hard cast materials and tempered aloys

9% cobalt making it one of our hardest and most wear resistant grades making it excellent for hardened die and mold applications, high silicon aluminum, Kevlar, CFRP, graphite. High cutting speeds and used for dry cutting in steel. Adding an Hard Carbon coating makes this an outstanding combination for aluminum applications.
