Based on our own experience these titanium nitride coated carbide cutting tools are the perfect solution for industrial drilling needs... The sharp edges and high-quality material make the bits last longer, even with heavy-duty use. The titanium nitride coating provides an added layer of protection, which minimizes friction, and reduces wear and tear. However, the only downside to these bits is that they may be slightly pricier than other industrial-grade bits. Overall, we highly recommend these bits for anyone looking for a reliable and durable industrial drill bit..
