SL 808

SL 808

Maximum toughness combined with excellent wear resistance make the new silicon nitride ceramic SL 808 the universal grade for rough milling of gray cast iron and ductile cast iron in high-performance applications. High machining speeds ensure high material removal rates with extraordinary process reliability even under rough cutting conditions. Removal rates can increase by 40% or more compared to conventional cutting ceramics.
