A heavy-duty construction for drilling in tough materials and a 135 degree split point that helps with self-centering to reduce thrust and improve penetration. Highlights the exceptional oxidation resistance and extreme hardness provided by the material. It compares TiCN coating to TiN coating, stating that TiCN is harder and has a lower coefficient of friction. Recommends using TiCN coating in situations where moderate temperatures are generated, as it greatly increases resistance to wear.
