Three grades of nodular cast iron (60, 80, and 100) were tested to determine the tool life of carbide and ceramic cutting tool materials. Tool life for all tools was much greater for grade 60 than for 80 and 100. Cast iron cutting grade carbide K6 was superior to steel cutting grade K3H, and at high speeds the ceramic was superior.
