The low friction coefficient of the titanium nitride coating helps reduce the buildup of heat and friction on the surface of the drill bit. Rather than needing to replace them regularly, they can last for many years, even with daily use. Thanks to their significant hardness and wear resistance, titanium drill bits have a much longer lifespan than uncoated high-speed steel drill bits.

The following are just some of the benefits that titanium drill bits offer. What Are the Main Benefits of Titanium Drill Bits? Overall, they are incredibly capable of drilling through most surfaces you would encounter with basic drilling tasks, which is why they are considered to be an all-around drill bit. The titanium coating also changes the color of the drill bits, which is why titanium drill bits have a distinct gold color. Since titanium nitride is strong, it increases the overall hardness of the drill bits, as well as their heat resistance and durability. Instead, the high-speed steel is coated with a layer of titanium nitride. Titanium drill bits are also composed of high-speed steel however, the steel is not combined with another metal, which is the case with cobalt drill bits. This explains why they are among the more popular choices for professionals and DIYers. While they are more expensive than a basic high-speed steel drill bit, cobalt drill bits are relatively affordable and can function as reliable, general-purpose drill bits. While they are often used for drilling through hard surfaces, a cobalt bit can also handle tasks that are not quite so demanding. You can also use them to drill various surface materials, including metal, plastic, and even wood. Since cobalt drill bits have high heat resistance and incredible strength, they are versatile. Not only can they handle drilling through much harder surfaces, but cobalt drill bits also tend to last much longer than softer alternatives. This means that cobalt bits can maintain their sharpness for much longer than a basic high-speed steel drill bit. Hardness of the Drill BitsĪdding cobalt to the high-speed steel makes it much stronger. This reduces the risk that the drill bit will warp or fail when exposed to high temperatures. The cobalt content within the drill bit helps dissipate heat throughout it, so it is not concentrated in one area. This heat resistance makes them a practical choice for any type of drilling application where high temperatures will be generated, like drilling through thick, hard surfaces. High Heat ResistanceĪs mentioned, cobalt bits can withstand an impressive amount of heat. To help you choose the type of drill bit that comes closest to meeting your needs, we have highlighted the most prominent benefits that cobalt drill bits offer. What Are the Main Benefits of Cobalt Drill Bits? Not only does this ensure that they last longer, it means that cobalt drill bits can handle hard materials, like stainless steel surfaces, cast iron objects, and other metals and alloys that would be difficult to drill through with a softer drill bit. The cobalt is added to the high-speed steel to increase the resulting drill bits' overall strength and durability. When an HSS drill bit is combined with cobalt, the result is a drill bit that is incredibly durable and impressively resistant to heat. Typically, a cobalt drill bit is made from high-speed steel (HSS) blended with cobalt to create a high-strength alloy. What Are Cobalt Drill Bits?Ĭobalt drill bits are incredibly popular, as they offer plenty of qualities needed from a long-lasting drill bit. We will also explore what they are designed for, which will help you choose the right drill bit set for your unique needs.

We will not only explain the differences between these two popular drill bit types but also dive into the characteristics and advantages they offer. We have created this complete guide to cobalt vs titanium drill bits to help you choose the right drill bit for your needs. While they are undoubtedly top choices, many people do not know their differences or what each type of drill bit is used for. Not only is it essential to invest in high-quality drill bits to achieve accurate and efficient drilling results, but you also need to ensure that the drill bits you use can handle the material you are working with.Ĭobalt and titanium drill bits are usually considered among the best options. No matter how often you need to use a drill, you must use the correct type of drill bit for the task at hand.
