The edge



Stainless steel is often used in aerospace and automotive industries because they are durable and corrosion-resistant. However,

Stainless steel is hard to process and hardened


  • machining hardening requires high cutting force to reduce tool life.
  • high strength performance leads to chip breakage.
  • low thermal conductivity leads to high temperature of cutting tool tip, leading to tool wear.
  • high chemical reactions lead to jamming and clogging during wafer evacuation. This results in the erosion of the rake surface and the destruction of the cutting edge

Exxtral + (AlTiN)

Aluminum and Titanium Nitride

It is ideal for high performance processing of hardened materials. Its chemical composition makes its hardness high, is a kind of characteristic

It requires cutting hard material. In addition, Exxtral + coating corrosion resistance increase temperature up to 1470 ° F; The temperature is significantly higher than that of tin.
