This is an ultra-fine cemented carbide grade with WC particle size of less than 1μ, and with excellent chipping resistance.
Its high hardness and transverse rupture strength provide excellent performance in applications where sharp edges are required.
This grade’s wear resistance is higher than EF05 due to lower Co content, however fracture toughness is reduced by one rank.
