Cobalt Vs Titanium Drill Bits: Are They Same?

Drill and set of drill bits

The world of DIY projects has evolved over the years, thanks to a number of technological advancement in the tools involved. Undoubtedly, this trend of advancement has caused and stirred a number of confusion in craftsmen. Many of times, people find it hard to identify the best tool, let alone attachments for them. That is why we put this post together on Cobalt vs Titanium drill bits to further assist you on the projects at hand.

From the name, drill bits are attachments alongside your drills that can wreak havoc on metals, hardwood, and plastic through holes. However, these drill bits come in different types just as we have different types of drills. The most durable types include the cobalt drills bits and the titanium coated drill bits. Unfortunately, there exists a number of differences between these two drills bits more than meet the eye. In the Cobalt vs Titanium drill bits, we will take a look at both drill bits types and put a clear distinction between them.

These drill bits perform similarly, which makes differentiating between their performances hard to identify. It takes a pro who has worked with the drill bits and has enough familiarity to put a clear distinction between the two types. However, you need to know the differences so as to end up with the right drill bit for your impact driver. This sole decision will ultimately affect the quality of your projects.

In the Cobalt Vs Titanium drill bits, we will identify some similarities. Of course, we won’t leave out the difference, which remains quite more important than the already known similarities. At the end of all the sections in the Cobalt vs Titanium drill bits, you should identify which drill bit is best for you.

Applications of the Cobalt vs Titanium Drill Bits

We’ll kick off the in-depth review of the Cobalt vs Titanium review with a few similarities. This way we move from known to known. Firstly, you should know that you can use both drill types with the same type of power drills. This means upon purchase of either drill bit type, you wouldn’t have to purchase a special tool to use a drill bit over the other.

Furthermore, the drill bits look alike except for the noticeable difference in color. In addition, they serve many of the same purposes and useful for almost all project needs. Both Cobalt and titanium bits belong to the high-speed steel (HSS) bits class. The HSS bits are made from steel. However, there exists a thin line between the cobalt vs titanium drill bit even though they come from steel.

The build quality of these two drill bits types is such that, they can cut through hard materials including metals, unlike other drill bits. They stand with the best bit types and remain some of the most durable bits on the market. Due to their sheer performance and strength quality, you can use them on metals and even hardwoods.

Metal Workpieces

Still talking about the similarities observed in the cobalt vs titanium drill bits, we take a look at their functionality in drilling metal workpieces. Undoubtedly, metal projects including materials iron, steel, and aluminum remain the most common application for both drill bits. When making holes through metal materials you will need to use tough and durable drill bits. Cobalt vs titanium drill bits possess the resilience needed and won’t break or warp when making holes and drilling screws through the material.

Remember they belong to the HSS drill bit class. This means, the bits work with high-speed drills and pin at top speeds while powering through hard materials like metals without losing their shape.

Wood Pieces

Still talking about the similarities observed in the cobalt vs titanium drill bits, we take a look at their functionality in drilling wood workpieces. Some woodworkers decide to make use of these drill bits on their projects, unfortunately, they sometimes have more than the required drilling power.

Talking about the build design, they resemble the familiar twist bits made for wood. Furthermore, they have similar corkscrew design seen on the twist bits. This helps the bit create important guides and holes in different materials.

However, when you take a close look at the tips of both drill types (Twist & cobalt vs titanium drill bills) they have different tips. In the twist bits, there exists a sharp pointed piece on the tips commonly referred to as a brad. The brad allows the bit to pierce the work material without slipping.

However, in cobalt and Titanium cobalt, you only have an angled tip with no brad. This means when you use these bits them on wood surfaces, there exists a high tendency for the bit it slips as you drill. This singular risks can case your wood piece to become splintered or split.

Consequently, you can use cobalt vs titanium drill bits on wood workpieces. But due to the drilling power, you should not make it your run to bits.

Cobalt vs Titanium Drill Bits Differences

Having discussed the similarities between the two bits, and the applications, we move to the differences. There exist slight differences that may have a huge impact on the outcome of your projects.

The most significant difference stems from the build design of the two drill bits. Remember they belong to the HSS class and their build material includes high-quality steel. Although they take on similar projects, function like every other drill bits but these two don’t act in any similar way. Apparently, cobalt and titanium coatings can case your drill bits to function differently.

The high-quality steel used in making titanium bits becomes coated with titanium nitride or titanium carbonatite. This actually brought about the name "Titanium bits." These coatings have gold and bluish-gray colors respectively. Unlike in cobalt bits without coatings, the titanium layer helps to increase the resilience of the bit. In addition, it helps to resist wear and tear, even at mind-boggling speeds at which these bits spin.

Cobalt bits on the hand, have no coating at all, just pre steel alloy and cobalt. Instead of drawing strength from additional coatings, the cobalt bears the responsibility for the overall strength of the bit. Furthermore, it helps to keep the bit spinning at the barest minimum temperature. Even as it spins against other metal materials.

The most notable differences between the cobalt vs titanium drill bits include the following:

Sharpening The Bits

Drill bits can never remain sharp forever. Eventually, you will need to get the bits back in shape by sharpening them. In fact, you will need to do this often especially when you use them on hard and unforgiving materials. When sharpening titanium bits, you might end up rubbing the coating off. This stands as a huge downside to the functionality of titanium bits.

On the other hand, cobalt bits have no coating. This means there exists no risk of surface stripping when sharpening cobalt drill bits. For craftsmen who engage in regular drilling duties, you might have to consider your options well before opting for titanium drill bits. Remember the titanium coating stands as the selling point of this bit type and once you lose that you lose the bits.

Therefore, you will have a longer life span of cobalt drill bits, contrary to the titanium drill bits that loses its coating over time.

Compatible Materials

Earlier we mentioned that you can use both cobalt and titanium drill bits on materials like hardwood, metals and even plastic. Even though these two bits appear to act like a jack of all trades, they have their area of specialization. This means they have materials they work better on even though they can drill holes through most materials types.

When it comes to softer materials like wood, plastic, and soft metals, titanium drill bits work perfectly. However, you also have to consider the coating type as titanium carbonitride coating can handle tougher materials unlike its counterpart: titanium nitride coating.

On the other hand, cobalt drill bits remain the best choice for tougher materials. For example, when working with materials like cast iron and other abrasive metals, use cobalt drill bits.  particularly abrasive.

Temperature

During the drilling process, the temperature that rises due to the metal to metal contact raises concerns. Fortunately, when it comes to the dissipation of heat you can hardly differentiate between the cobalt vs titanium drill bits.  Both drill bits do an excellent job in distributing the heat over the surface of the bits. This ensures you do not damage either the bits or the workpieces.

Cobalt drill bits dissipate the heat from the metal to metal contact by distributing it over the contact surface. This makes it possible for the bits to resist the damage from this tremendous heat production. Similarly, the titanium drill bits dissipate the heat effectively keeping the bits as intact as possible. The coasting stands as s barrier between the steel bit and the metal work surface.

In fact, you will find out that the coated titanium drill bits dissipate heat way better than the cobalt bits. Unfortunately, this fact only remains credible so far the coasting doesn’t become damaged or miss in some spots. This means the efficiency of the titanium bits revolve around the amount of coating it can retain after each sage.

Cost

The price factor has always been a major distinguishing criterion. It helps to put a huge gap between the DIYers and the industrial professional workers. In fact, when it comes to power tools, you cannot neglect the effect of respective tags. Industrial workers tend to spend more than the occasional DIYers. Because DIYers just want to complete a few projects and not taking in craftsmanship in the long run.

Similarly, how much you are willing to spend on cobalt vs titanium drill bits will be a determining factor in whatever you end up with. As expected, there exists a major difference in the cost of the two bit types. The manufacturer and the actual materials used in the making of the bits determine the eventual cost. however, you should prepare to pay more for cobalt bits.

Cobalt bits offer more durability and this comes at additional cost. However, you will have the value for your money when you keep using the bits even after several sharpening cases. Unlike the titanium bits, you have to be selective with its application and sharpening because once you lose the coating you lose the bits.

Conclusion

As a craftsman, you should be able to see beyond the present needs. this way you will save yourself the cost of having to purchase different tools over a short period of time. since you won’t purchase for the current need alone but also keep the future goals in view. Although the cobalt vs titanium review has been as in-depth as possible, we believe it should help you make the right decision.

The materials you will work on play a huge role in the type of bit you will end up with. For craftsmen who will work on harder materials like cast iron and stainless steel, the cobalt bits remain the best selection. Due to its superior durability, efficient heat dissipation and the ability to sharpen the bit, you already have enough reason to back up your decision.

On the other hand, if you will have to work with softer materials like hardwood, you should invest in the best titanium bits.

Also, the duration of your project plays a vital role in your decision making. If you want to have a long lasting bit, you had better invest in the best cobalt bit. Definitely, because you can sharpen it a number of times before it eventually becomes thin or breaks off. However, you can get the titanium bit for cheaper prices and if working with a budget has more importance, then you should opt for the titanium bits. For a far lower price than the cobalt bits, titanium bits will serve you for a long while too.
