Titanium vs Cobalt Drill Bits – What is the best?

There are many different types of drill bits available. There are advantages and disadvantages to each
option, therefore one is not always superior to the others. Making the appropriate choice is crucial to
completing any assignment effectively and accurately. You'll need to decide between titanium vs cobalt
drill bits for your applications. From this article, we will be comparing those two options, so that you can
decide which one is the best for you.

These two bits are more enduring and resilient than other drill bits since they are made to drill into
metal. But there are minute variations between them. As we previously said, none of these will always
be the ideal option. They are really situational, and you will choose based in large part on the tasks you
are working on.
What are cobalt drill bits?

In the first part of titanium vs cobalt drill bits comparison, we will help you to learn what cobalt drill bits
are all about. Cast iron and stainless steel are two common metals that cobalt drill bits may cut through.
We shall go into more detail about this momentarily, but they are not constructed entirely of cobalt.
They do, however, contain a little amount of cobalt, that is how they got their name.
Cobalt drill bits are created by adding a tiny quantity of cobalt to a base alloy (often steel). The amount
of cobalt added by manufacturers varies by brand and is typically between 5 and 7%. The basic alloy
becomes very strong and durable when cobalt is added. Additionally, cobalt melts at a temperature
greater than steel. Cobalt melts at around 2723 degrees Fahrenheit, whereas steel melts at about 2500
degrees F.

A greater melting point is significant because it indicates that the cutting edge will withstand more of
the heat produced during cutting. The drill bits can stay sharper for a longer period of time due to the
increased heat resistance. Additionally, they must be able to handle tougher materials without
becoming exhausted.
Comparatively to conventional HSS drill bits, cobalt bits offer a greater variety of useful applications.
They are most often employed to sever tough materials which steel alone might find difficult to cut
through.

Why are cobalt bits undesirable?

Cobalt bits can be used in softer materials, but I wouldn't suggest using them on items like wood or
plastic. Performance is not really at issue here; rather, it is cost. When a less costly substitute will work
just as well, there is no purpose in employing a pricey drill bit for natural fibres. Cobalt drill bits should
only be used for tasks where they perform better than less costly alternatives.
Cobalt pieces are fairly fragile, so that's something to keep in mind. You must take good care of, store,
and take special care to not drop them. Although they are exceedingly hard, they are also highly fragile
and are susceptible to breaking. If you're not cautious, this might get extremely pricey.

Although metal is their principal use, they may also be employed with softer materials. Because of their
extreme toughness, they may be used when other parts simply cannot.
-Temperature

Every metal-on-metal component will heat up. That is simply the result of fast rubbing two metals
together. Cobalt blades, meanwhile, are designed to disperse heat. Cobalt excels at distributing heat
evenly over the contact area. Even at high speeds, they can swiftly disperse heat.

-Sharpening

Sharpening cobalt bits is not difficult at all. Since they are uncoated, sharpening them does not result in
surface peeling. They live longer as a result, which ultimately saves you money. Cobalt bits may be
sharpened several times before they lose their usefulness.

Cobalt bits have the major benefit of being able to sharpen, enabling you to be get more use out of your
purchase. Within a bench grinder, you can quickly sharpen worn-out drill bits, but it's best to practice on
some used drill bits first though you understand what you're doing.

Sharpening the drill bit doesn't run the danger of removing any of the improved material qualities since
the cobalt is alloyed well with steel instead being merely a coating. Given the cost of a high-quality set, I
believe this to be a huge plus.

-Material

Cobalt as well as steel alloy are combined to create cobalt drill bits. They typically include between 5%
and 8% cobalt and the remainder is steel. As a result, they are very resilient and can cut through even

the hardest materials, like cast iron. As the bit spins against other metals, the cobalt also keeps it from
becoming too hot.
-Cost
Cobalt pieces are often fairly pricey. They are longer-lasting and more resilient than other choices, such
as titanium. They often enable you to save money over time as a result. Whether you choose to spend
more now or afterwards depends on your preferences.
Cobalt parts often provide decent value for the money despite being more expensive, mostly since you
can use it for such a long time.
What are titanium drill bits?
The next section of this titanium vs cobalt drill bits comparison is to understand what titanium drill bits
are all about. Cobalt drill bits and titanium drill bits are comparable. Additionally, they are designed to
drill through harder materials like metal. Although they initially have a very similar appearance to their
Cobalt relatives, they have a few little distinctions that distinguish them from them.
Titanium drill bits: what are they?
Most titanium drill bits are constructed from HHS steel and coated with titanium. Different titanium
alloys enable a range of applications. The 3 varieties are:
Titanium nitride is resistant to high temperatures.
Greater durability and resistance provided by titanium aluminum nitride.
The strongest alloy suited for heavy mechanical stress is titanium carbide.
By using a titanium coating improves the cutting edge's surface hardness while also decreasing friction
and offering corrosion protection. However, since their melting point is lower than that of cobalt, they
are often not as strong. Nevertheless, they are still more adaptable than a typical HSS drill bit. The steel
core is shielded by the titanium alloy covering, which also keeps it bit sharp for longer.

What Purposes Do Titanium Bits Serve?

Compared to traditional HSS bits, titanium carbide inserts have many more applications. Since you can
have them on both soft and hard materials, they are perhaps a little more adaptable than cobalt drill
bits.

Why are Titanium Bits Unsuitable?

Although tougher materials such cast iron may be drilled through with titanium bits, cobalt drill bits
eventually become more advantageous. Harder materials accelerate the removal of the coating, which
wears the bit down more quickly.

Consider the material you're drilling while selecting the ideal titanium drill bit. For tougher materials,
you should use a platinum carbonitride bit, although wood or plastic will work just fine with titanium
nitride.

-Temperature

Things will become heated while drilling into metal using a metal bit. The majority of drill bits on the
market today that are built for harder materials contain some kind of heat-dissipating design element.
It's the titanium coating on drill bits made of titanium. This layer disperses the heat along the surface
while shielding the metalcore bands from it. This covering does, however, deteriorate with time. Once it
becomes too thin, it won't function properly.

-Sharpening

Titanium blades can be sharpened because of the coating. This coating will deteriorate over time. Much
of the bit's heat resistance would have been lost by the time the coating was totally gone. This is a
concern when drilling metal because metal-on-metal may heat up quickly and very hot. This coating is
removed along with the titanium drill bit when it is sharpened. Because of this, the titanium drill bits can
only be sharpened so much before they lose their use. They have brief lives.

-Material

Drill bits made of titanium are not totally composed of titanium. Instead, they feature a titanium
covering over a metal core. As we will see later, this titanium is crucial for reducing overheating. These
chunks do not, however, contain any cobalt.

While the material differences between cobalt as well as titanium drill bits are a noticeable difference,
in actual use you generally won't notice a substantial difference. The substance only distinguishes the
bits in a select few circumstances.

-Cost

Cobalt drill bits are often more expensive than titanium drill bits. They do not, however, endure as long
since the covering gradually wears off. This may ultimately cost you more money, as you can expect. Of
all, not everyone need a sturdy item that will endure for a long period. A titanium drill bit should be
enough if you just need to punch a few holes. However, titanium bit replacement costs may mount up
for people who often drill into metal.

Titanium vs cobalt drill bits – What is the best option?

Again, there is no superior drill bit among these two. It depends on the material you're using and the
goal you're attempting to achieve.

-Pick titanium when you work with wood and soft metal

Select titanium when working with soft metal and wood. Having said that, titanium bits work best with
soft metals like wood. When compared to these softer materials, they will cost you fewer up front and
last longer. Harder materials need more frequent honing, which may rapidly wear down their coating.

Overall, both of these bits are capable of handling harder materials and have good heat dissipation.
Depending on how much cash you have to invest up front, how often you expect to use the bit, and the
material you need to drill, you will need to decide which choice is best for you.

-Choose Cobalt for Versatility

You need a collection of cobalt bits if you deal with a range of materials. This is clearly explained in this
titanium vs cobalt drill bits comparison. They may be utilized with even the hardest materials and will
simply endure longer. Although DIYers with many of tasks will find them useful, they are better for
specialists. Obviously, this assumes that you have enough cash on hand to spend up front. Cobalt bits
cost far more than titanium ones. However, since they last longer, you'll ultimately save more money.

What Sets Cobalt Bits Apart from the Competition?

As already indicated in the titanium vs cobalt drill bits comparison, the increased heat resistance of
cobalt bits is their principal benefit over materials like high speed steel.
This prevents equipment damage when working with tougher materials like cast iron and stainless steel.
Furthermore, drilling may be done without cooling fluid for extended periods of time. While I usually
suggest using coolant while drilling metal, it will always increase their lifespan.

You should expect them to last you a long time than a typical HSS drill bit because of their superior
construction and sharpening capabilities.
The primary benefit of cobalt drill bits over titanium drill bits is that cobalt is alloyed further into bit
rather being applied as a coat. Cobalt drill bits can be repeatedly sharpened, but titanium drill bits burn
out more slowly.

What Sets Titanium Bits Apart from Competition?

Titanium bits have better heat strength and good than high speed steel, which is their major benefit.
They are thus a better option for softer fabrics since you will use them a lot more. We helped you to
learn more about it in this titanium vs cobalt drill bits comparison.

Additionally, titanium has a lower beginning cost than cobalt. Although it'll take some time, eventually
you could wind up spending more on titanium bit replacements.
Titanium will be an excellent option if you're simply a regular DIYer who wants a set of reasonably
durable and adaptable drill bits. It will take a long time to degrade over time the coating if you just use
them occasionally for tasks around the house.

Which Drill Bit Is Best for Me: Cobalt or Titanium?

In this titanium vs cobalt drill bits comparison, you were able to gather a lot of useful information about
these two different types of drill bites available int the market. So, titanium or cobalt is superior, right?
Since the answer varies on what your needs are from your drill bits, there just isn't one right answer. We
will advise investing in nice cobalt drill bits if you plan to use them often for hard materials. Over time,
you'll unquestionably receive your money's worth. But titanium drill bits is a better choice if you often
deal with softer materials.
Overall, cobalt bits provide pros and DIY enthusiasts more options. But for softer materials like wood
and soft metal, titanium is a more economical option. Hopefully, this article has assisted you in reducing
the number of drill bits you need to choose from for your project. Follow what you learned out of this
titanium vs cobalt drill bits comparison, and make sure that you spend your money on the best drill bits
