9% grade for drilling and end milling. One of our hardest and most wear-resistant grades making it excellent for hardened die and mold applications, high silicon aluminum, Kevlar, CFRP, and graphite. High cutting speeds and dry cutting in steel. Adding a Hard Carbon coating makes this an outstanding combination for aluminum applications.
GC060F / DK120
6% premium grade for drilling and reaming CFRP, graphite, hardened steel, and grey cast iron. Also approved for CVD-Diamond coating. Excellent choice for reaming applications.
