15 () TiN (Titanium Nitride) coating Titanium Nitride gives the ol a higher performance in comparison traditional noncoated drills. TiN coating, with good allaround properties, is recommended for the general application, i.e., attack by abrasive, adhesive and chemical wear in equal proportions. () TiCN (Titanium Carbon Nitride) coating TiCN coating should be employed when severe thermodynamic stress is expected, for example when drilling in high hardened steels or in mild steels with high speed and feed. () TiAlN (Titanium Alumium Nitride) coating The addition of Aluminum the Titanium Nitride produces an increase in hardness and an exceptional increase in resistance oxidation at high temperature. TiAlN coating is applied drilling with severe thermal stress on cutting edges when continuous nonstep feed, dry cutting or high speed cutting.
