What Are Cobalt Drill Bits and What Are Cobalt Drill Bits Used For?

Cobalt drill bits are very popular because of their tough steel design; however, they are more than that. In addition to high-speed steel, they feature five and eight percent cobalt in their design, thus making them highly efficient and capable of withstanding a lot of abuse and applications. As a result, they are the primary choice when drilling through hard materials. Cobalt drill bits ensure that you get through materials quicker and easier where other standard bits fail.  

Another great thing about cobalt drill bits is that they are highly resistant. They are capable of enduring hot temperatures without breaking or shattering. Moreover, sharpening them in case they get dull is not a problem.

What Are the Different Qualities of Cobalt Drill Bits?

Cobalt drill bits are highly efficient and are ideal for working with hard metals. Dealing with cast iron or stainless steel is not a problem for them, either. Moreover, they are durable and can be sharpened many times before being replaced. 

What Are Titanium Drill Bits and What Are Titanium Drill Bits Used for?

The core of titanium drill bits is made from high-speed steel with an exterior coating of Titanium-Nitride. They are ideal for working on plastic, wood, and soft metals, such as aluminum or magnesium. The Titanium-Nitride or TiN coating helps reduce friction which, in turn, decreases the chances of high heat production, thus ensuring the durability of these bits.  

In addition, these bits work well with harder types of wood, including knotted wood, copper, brass, steel, and PVC. Moreover, they work well in metal cutting machines and help to drill precise holes.  

Cobalt vs. Titanium Drill Bit Similarities and Differences

Although cobalt and titanium drill bits are used for a number of similar applications, it is their differences that make them suitable for a particular project. Here’s a rundown of their similarities and differences to make things clearer. 

Cobalt and Titanium Drill Bit Similarities

The similarities between the two drill bits are as follows:

Dissipating Heat

Both cobalt and titanium are made from metal and do an excellent job of dissipating heat, thus protecting your bits or materials from damage.  

Cobalt and Titanium Drill Bit Differences

The most notable differences between titanium and cobalt drill bits are:


Titanium bits are coated with titanium nitrate, or titanium carbonitride, which comes in bluish-gray or gold color. These coatings, while increasing the strength of these bits, prevent excessive wear and tear when operating at high speeds. Meanwhile, cobalt drill bits do not have any coating. They are made with cobalt and steel alloy, with the former enhancing the overall bit strength and preventing it from becoming too hot.   

Sharpening the Bits

Using the bits regularly can cause them to become dull, and you will have to sharpen them in order to ensure their efficient use. It is important to be careful when sharpening titanium bits as they have a coating you might rub off when you use a sharpener to maintain their top shape. 

There’s no coating on cobalt drill bits; therefore, there is no risk of any coating stripping away when sharpening. Consequently, they may have a longer life span as compared to their titanium counterpart. 

Compatible Materials 

Both titanium and cobalt drill bits work with plastic, metal, wood, and other materials. However, the former is a much better choice when working with softer materials, while the latter works best with tough materials like cast iron and other particularly abrasive materials. 

Top Pick Between Cobalt and Titanium Drill Bit

So, which drill bit will be right for you? After discussing the merits of both these drill bits, we can see that cobalt drill bits are ideal for heavy-duty procedures. Their high resistance and durability make it easier to drill through most materials. Titanium drill bits, on the other hand, are not highly durable but provide excellent performance throughout their lifespan.    

Which is Better, Cobalt or Titanium Drill Bits?

Investing in the right drill bits is essential to successfully complete your project. Make sure that you keep your project details in mind when checking the drill bits’ specifications so that you get the ones that are best suited to the job. Otherwise, you may spend money on a product that may not be suitable for you.
