Advanced Coating Technology
The implementation of state-of-the-art coating technology significantly enhances the performance capabilities of these carbide drill bits. Multiple layers of advanced PVD or CVD coatings, often including combinations of titanium nitride, aluminum titanium nitride, and diamond-like carbon, provide exceptional protection against wear, heat, and chemical reactions with workpiece materials. These sophisticated coating systems reduce friction coefficients, enabling higher cutting speeds while maintaining tool life. The enhanced surface hardness provided by these coatings, often exceeding 3000 HV, creates an additional barrier against abrasive wear and built-up edge formation, ensuring consistent performance in demanding applications.
