EXXTRAL-Plus

EXXTRAL-Plus – For high-performance cutting

EXXTRAL-plus, a coating based on aluminum-titanium nitride, for the highest requirements in the cutting of hardened steel, M case of high performance cutting with or without cooling lubricant.

The anthracite-colored EXXTRAL-plus is characterized by a very high hardness. The properties are retained up to high thermal and mechanical loads. EXXTRAL-plus is highly inoxidizable and is provided with a low heat conduction coefficient.

  • Especially smooth and dense.
  • High resistance towards oxidation (800°C)
  • High hot hardness
  • Enhanced toughness
  • Chemical resistance
  • Low thermal conductivity coefficient
  • Higher cutting speeds
  • Longer service life
  • Improved surface quality
  • Dry machining
  • No cooling lubricant required
