Ceramic

Ceramic

Ceramics inserts are capable of machining at high speeds. Recommended

for hard turning of hardened steel or rough to finish turning of cast iron and

heat-resistant alloys.

Features

  • Excellent wear resistance enables high speeds machining of cast iron
  • Ceramic maintains good surface finishes due to the low affinity to

workpiece materials

  • Silicon nitride ceramic can machine cast iron with coolant due to its superior

thermal shock resistance
