Coating Description Technical data
TiN
(Titanium)
Proven, cost-effective all-round layer for significantly improved performance.
Colour: gold
Vickers pyramid hardness: 2200 HV
Layer thickness: 1.5–7 μm

TiNAlOX
(aluminium oxide)
Stands out for high wear volume and temperature resistance,
for extended tool life.
Particularly suitable for rough cutting.
Suitable for medium cutting.
Colour: blue
