KYOCERA’s ceramic grades are designed to resist oxidation and maintain hardness at elevated TOOLHOLDERS SMALL TOOLS G
temperatures. H
J
FEATURES
• E xcellent wear resistance for high cutting speeds
• C eramic maintains good surface finishes due to the low affinity to workpiece materials
• S ilicon nitride ceramic has improved thermal shock resistance allowing cast iron cutting using coolants
