Titanium Vs Cobalt Drill Bits | Which Is Great for Metal

You’ll find a large variety of drill bits on the market. There isn’t always a better option than the rest, but each has its advantages and disadvantages. Of course, any project must be done correctly and efficiently for it to succeed. Most of the time, you’ll have to choose between titanium vs cobalt drill bits and for more complex undertakings.

Designed for drilling into metal, these bits are more robust and complex than most drill bits. However, there are some minor changes. As previously stated, neither of these drill bits will always be the ideal option. They are very dependent on the projects you’re working on, and you’ll have to make a decision based on that.

What are Titanium Drill Bits

Bits with a titanium nitrite coating are known as titanium drill bits because they are constructed of high-speed steel. Some advantages of titanium coated bits over steel are excellent wear resistance, the capacity to endure higher temperatures, and enhanced durability.

Titanium coatings are most usually seen in three distinct forms.

  • Nitrided Titanium
  • Tungsten Carbo-Nitrification
  • Aluminum Nitride

What are the differences between these coatings?

TiN is a titanium alloy.

As an entry-level coating, these are the most typically utilized options. The vivid gold hue may recognize them on their skin. The TiN coating is found on the majority of golden-yellow wood drills. However, This material is coated with countersink bits, router bits, milling cutters, and other cutting tools.

Carbo-nitriding of titanium

In comparison to the standard titanium nitride coating, TiCN is superior. In addition, the coating is more durable and resistant to wear.

Consequently, drill bits coated with blue/purple TiCN perform better than those coated with TiN.

What is Titanium Drill Bit

The titanium aluminum nitride coating may sustain temperatures up to 800°C (1450°F). As a result, an aluminum oxide layer forms at high temperatures, reflecting heat into the chips. Increased productivity and cutting speed are possible because of this.

TiAlN-coated bits are ideal for drilling with interrupted cuts because of their gray-colored coating’s increased flexibility. In short, TiAlN-coated drills outperform TiN, TiCN, and black oxide drill bits in terms of performance.

But they are the most costly and cannot be used for drilling aluminum because of the high aluminum concentration in the coating. Additionally, there is AlTiN (Aluminum Titanium Nitride), a somewhat stricter layer than TiAlN, and several additional proprietary coatings to choose from.

The Feature of Titanium


This does not mean that Titanium Drill Bits are entirely constructed of titanium. In place of a titanium coating, they contain a titanium core. As we’ll see in a moment, titanium is critical in preventing overheating. Cobalt, on the other hand, is absent from these pieces.

Although the material differences between cobalt and titanium drill bits are significant, it’s unlikely that you’ll see much difference in actual use. Rarely does the content act as a distinguishing factor between individual parts.


A coating is applied to titanium blades. This layer will eventually peel off. The bit will have lost most of its heat resistance after removing the coating. This is difficult when drilling metal since metal-on-metal may get extremely hot very quickly.

This coating is also removed when you sharpen titanium drills. Because of this, titanium drill bits can only be sharpened so many times until they’re no longer functional. They only live for a brief period.


As soon as you start piercing metal, things will get heated. Most drill bits built for more complex materials are equipped with some design feature to disperse heat. However, the titanium coating makes titanium drill bits so unique. Protecting the metal core and dissipating the heat along the surface is done by this covering.

However, with time, this layer will begin to flake off. Do you know how to utilise a cobalt drill bit?.


To put it another way, titanium bit drills are more affordable.. However, the coating wears off over time, making them less durable. That was a bad deal that turned out to be far more expensive than you expected..

Of course, a long-lasting bit isn’t necessary for everyone. For example, a titanium drill bit may be sufficient if you only need to drill a few holes. On the other hand, the cost of replacing titanium bits may quickly pile up for people who often dig into metal.

However, with time, this layer will begin to flake off. Being overly thin will prevent it from doing its job properly..

What Are Titanium Bits Useful For?

Exceptionally Flexible For those looking for a drill bit that can easily penetrate soft materials, titanium is the best option. Drilling through wood or soft metals is a breeze with this drill bit. In addition, it is effective and accomplishes its work without a hitch.

Economical, to say the least titanium drill bit is an excellent choice for a drill bit that won’t break the bank. There’s no need to panic about the cost.

Over time, the parts lose their luster due to wear and tear. However, given their low cost, they are a good investment. Exceptionally Long Lasting abrasion-resistant coating on titanium makes it extremely long-lasting. Bits like these are built to last longer than on the market. So when it comes to drilling, this is the most significant drill bit you can get your hands on.

What Can’t You Use Titanium Bits For?

You can count on this drill bit to meet all of your do-it-yourself demands. This drill bit, on the other hand, is not resharpened. And because the coating wears out more quickly on more rigid materials, this isn’t a good option for them.

If you plan on using it to drill through cast iron, stainless steel, or other comparable materials, be prepared for the coating to wear off sooner than expected. But, aside from that, the valuable features of this device make it well worth purchasing.

What is Cobalt Drill Bit ?

However, with time, this layer will begin to flake off. Thinner material will not be able to perform its intended purpose..

What is a cobalt drill bit, and how are they used? Alloy steel with a cobalt concentration is used to make them. With a 5–8% cobalt content, this material is an improvement over standard high-speed steel.

These pieces are classified according to the quantity of cobalt they contain. For example, cobalt content in the alloys varies from 5% in grade M35 to 8% in grade M42.

These are not coated in cobalt like titanium drill bits. Instead, cobalt is used as a secondary alloying metal in alloy steel. Only one significant advantage can be gleaned from this.. The cutting edges may be resharpened without affecting their quality.

How to Use a Cobalt Drill Bit

Hard alloy steels, tool steels, spring steels, and aluminum alloy may be drilled using cobalt drill bits. However, extreme heat does not affect their cutting-edge sharpness. Therefore they can survive extremely high temperatures.


The drill press and cordless drills can utilize both types of drill bits. As a result, selecting between the two materials needs no specialised equipment or knowledge.. Titanium and cobalt have similar strengths and are frequently utilized in the same applications. The only thing that sets them unique visually is their color.

Both are designed to cut through hard materials that regular drill bits, such as those made of high carbon steel, cannot perform. Although they are primarily designed for metal, both may be used with hardwoods. Because they are so similar, there isn’t much distinction between them.

The Feature of Cobalt Drill Bit


Alloy steel and cobalt are used to make cobalt drill bits. Cobalt makes about 5 to 8 percent of the alloy, the remainder being steel. This makes them incredibly durable and able to break through cast iron and other hard materials. Additionally, the cobalt protects the bit from overheating when spinning against other metals.


Sharpening cobalt bits is a snap. There is no stripping of the surface when pointing them because they do not have a coating. The longer they last, the more money you save in the long run. Before they become useless, cobalt pieces can be sharpened numerous times.

Metal-on-metal pieces are likely to get hotter and hotter as time goes on. That’s precisely the way it is when you’re rubbing two pieces of metal together at high speed. Cobalt blades, on the other hand, are designed to disperse heat. Over the contact surface, Cobalt dissipates heat exceptionally well. So even at high speeds, they can swiftly disperse heat.

One of these blades won’t get too hot to touch.

The price of Cobalt pieces may be pretty high. Although titanium is a long-lasting alternative, it is not as sturdy and durable as other possibilities. As a result, they can help you save money over the long haul.. Is it better to spend more money now or wait till later?

For the price, cobalt bits are a fantastic investment because they last so long and can be used for so many projects.

What Are Cobalt Drill Bits Useful For?

Compared to other types of drill bits, cobalt drill bits offer a few features that make them stand out.


As a result of their solid and robust construction, cobalt variations are incredibly long-lived. As a result, you can keep using them even if the pieces are worn out by regularly sharpening them. This is an enormous advantage in terms of not needing to spend a lot of money on new bits every time one wears out.


It is possible to utilize a cobalt drill for various applications. As a result, you can put it to any purpose you like.. Drilling through hard materials isn’t an issue, but you must be a little more careful when working with soft ones.

Resistance Increased

When cutting through abrasive materials, no drill bit can match the effectiveness of these varieties. Drilling stainless steel or cast iron is a common request. This drill bit doesn’t have a problem with it.

What Can Cobalt Drill Bits Not Do?

Cobalt bits are lovely for drilling because of their exceptional performance, but they also have limitations, just like any other suitable product. The most significant negative of this drill bit is that it’s a little price’s.

We don’t expect you to toss this away as soon as it becomes dull due to its high cost. As a result, they must be continually improved if they are to remain successful.. You will need to invest in a proper sharpening device to get the most out of this bit.

For those on a restricted budget, this may be out of reach. But on the other hand, this cobalt drill has several valuable features that make it well worth the price.

What is the Difference Between Titanium Vs Cobalt Drill Bits

When looking for the perfect drill bit for a specific job, it’s essential to examine its form, size, and substance.

It’s also important to know if the solution you’re considering is appropriate for the material you’re working with. Another thing to consider is that certain components are better suited to specific materials than others.

It was using the incorrect bit on a surface other than the one for which it was designed can have fatal results. In addition to the risk of destroying the drill bit and maybe the drill itself, you could also injure yourself by using the wrong tool. Not to mention that the finished product wasn’t up to snuff.

What to look for when selecting drill bits if you don’t have a lot of time or money to play around with different types and materials?.


The way a drill bit drills through various materials are influenced by the geometry of the drill bit itself.

Wood drill bits, starting with the softer wood, are made to produce precise holes in the wood without causing it to break or split. They are less effective when used on non-wooden materials, such as metal or concrete. Many common types of bits include Brad point, auger, and paddle.. A new nook or crannies is created in the wood by each one of these tools.

Metal drill bits are meant for metalwork. HSS bits, also called high-speed steel bits, are more vital because of the steel they are comprised of. This prevents the drill bit from overheating while drilling through metal. They may be used on softer materials, such as wood, but you run the danger of splitting them because they are constructed of a more stiff substance.

The variety of materials that a multi-purpose drill bit can effectively penetrate makes it particularly useful. People who only use their drill on wood, ceramic, plastics, and even heavy metals choose this drill because of its flexibility. On the other hand, it does not produce as clean a finish as a specialized drill bit.

In other words, masonry drill bits were created with masonry in mind. Because drilling into masonry is more complex, diamond-tipped drill bits are used. If you’re working with porcelain or brickwork, these drills will ensure that the material doesn’t shatter or crack when drilled.

Also unusual is using unique drill bits developed for a specific task precisely. Unfortunately, drills aren’t often used for jobs like securely and neatly cutting through glass, so you’ll need a specialist.


Recess-making outcomes will vary greatly depending on the length and breadth of the drill bit. Therefore, you must supply these two parameters to drill a specific depth and breadth hole.

Those who need to use their drill more frequently for specific jobs may want to consider investing in a model tailored to their needs. Moreover, drill sets don’t usually come with a particular bit size you’ll require.

When drilling, a set of drill bits is the best option if you just use your drill for occasional tasks. Any project can benefit from its availability in a wide range of sizes and shapes.. This is a good option for average families and do-it-yourself.


There is a wide range of drilling performance depending on the drill bit material and coatings. However, three significant aspects affect the bit’s longevity, strength, and heat resistance: the material it is constructed of.

A tungsten carbide bit is suitable for drilling into hard materials, whereas a low-carbon steel drill bit is more commonly used for softwood. However, using a harsher bit risks harming and even fracturing the surface on softer surfaces. The same holds for devices constructed of sensitive materials when used on rough surfaces.

With more complicated materials, drill bits have a longer life expectancy than those constructed of softer materials. However, its long-term usefulness is contingent on proper upkeep and the tasks it uses.

Temperature resistance is a significant consideration when it comes to drilling. Excessive heat is generated when a drill bit comes into contact with the substance it’s drilling through. The probability of the bit slipping is another danger that a heat-resistant device may decrease..

Due to the use of coatings on the underlying material, drill bits are no longer damaged by overheating and have an extended lifespan as well. As a general rule, this is the way to go when using materials that would be too expensive to turn into an entire solid drill bit..

HSS is typically used for the underlying section of coated bits since it is less expensive. In addition, the covered item will benefit from the pricey material’s heat resistance, hardness, and long-term durability.

How To Extend The Life Of A Drill Bit

With a few simple steps, you can maximize the life of your drill bits. Maintaining the drill bits over time will make them less prone to breaking and ensure they operate at a high level with every use.

Storage in the Correct Manner

Keeping your drill bits in a dry location will help prevent rust from accumulating.


Another way to prevent rust is to apply machine oil after removing dust. It contains the drill bit from deteriorating before it is used again. The oil will ensure the drill is clean and free of any leftover material. It’s going to be around for a while.

Proper Cleaning

Smoother cuts and fewer scratches on the material and the drill bit may be achieved by cleaning the drill bit periodically as you work. In addition, dust may be kept at bay by rubbing a cloth along the bit.

Adjusting the speed

Using the right speed for the material you’re dealing with is critical to reducing the stress on the bit. Faster rates are needed for some materials, but not all. Speed is an essential factor in preventing the drill from sliding, as well as ensuring that the bit doesn’t become dull.


If you want to extend the life of your drill bit, lube it before using it on any surface.. When drilling at a fast speed, the bit’s frictional heat can cause damage to the substance it’s shot through. So using the wrong lubricant for the material you’re dealing with might end up causing more harm than good.\


Which is a better drill bit, cobalt or titanium?

Cobalt drill bits are more costly than titanium drill bits, but they have a longer life expectancy and are better able to withstand heat. It is also more durable and can drill holes in rigid metals using a cobalt-coated drill bit. However, titanium and cobalt drill bits are very different, and this comparison table shows the fundamental distinctions.

What are harder cobalt or titanium drill bits?

Coated titanium drill bits are more durable than undercoated cobalt drill bits. However, titanium drill bits cannot be sharpened. It is possible to point cobalt drill bits due to the steel used in their production. In addition to their excellent heat resistance, they are also harsh and abrasive.


Cobalt drill bits are more durable and can handle more challenging materials. This is the longer-lasting alternative between the two because of its capacity to be sharpened and its durability. As a result, you should consider this an investment.

If you’re looking for a more affordable option, titanium drill bits are excellent for drilling into soft materials. Unlike their cobalt counterparts, this bit’s covering will survive for multiple uses, but it will wear out much sooner.

In terms of performance, which one is superior? Again, the material you’re working with is the sole determining factor in which drill bit you should use.
