Extra strong, has high heat resistance. Used for cutting toolsteels of RC 45 and higher.

CTS - TiCN
(Titanium Carbon Nitrate) Excellent wear properties in Aluminum, Kurtzite and other non-ferrous materials.

CTD - Diamond
Diamond coatings are used when milling Graphite.

CTA - AlCrN
(Aluminum Chromium Nitrate)
AlCrN based coatings are more oxidation resistant and have markedly greater hot hardness than conventional coatings, thus ensuring stability under extremely high thermal load.
