Last update on 2022-01-05 / Affiliate links / Images from Amazon Product Advertising API
Confused between which type of cutting tool you need to expertise your technical skills. People often use a drill bit to remove materials or to create holes or even to cut through any workpiece. But, there’s a lot of confusion while choosing a Cobalt Drill bit or a Titanium Drill Bit. They have different purposes and different benefits for opting for any one of them. Still, a lot of people do get confused while selecting the best drill bits for metal and their usage. Here is a comparison between Cobalt vs Titanium Drill Bits that you can always choose as your favorite choice.
What Exactly a Cobalt Drill Bit?
Do not go for the name if you are thinking that a Cobalt Drill is completely made up of Cobalt. In fact, it is a steel alloy which has 5 to 8 percent Cobalt. The 5 percent alloy is known as M35 grade while the 8 percent alloy is known as M42 grade. Cobalt actually helps to increase the strength as well as makes it more heat resistant. The Cobalt Drill is one of a kind and it surely helps a lot to drill hard materials quickly. It is basically because of the friction of metal against metal which increases the temperature and makes frilling easy.

What is Titanium Drill Bit?
Titanium Drill Bit is composed of a metal formation which includes Titanium Nitride and an alloy of High-Speed Steel Metal. This Drill Bit has a high surface hardness which makes it very corrosive resistant. This type of drill bit is ideal to cut through hard metal in no time. Titanium Drill Bit is mostly used by professionals who look for fast drilling through hard metal. Basically, if you go through the specifications, the Drill Bit is actually a coating of Titanium on hard steel.

Cobalt vs Titanium Drill Bits [Comparision]
Compositional Difference
Cobalt
- Cobalt Drill Bit is a composition of metal alloy along with cobalt.
- It composes of 90 percent metal alloy along with just 5 percent Cobalt.
- This composure allows the blade to resist high temperatures and high friction
Titanium
- Titanium Drill Bit is a composition of high-speed steel along with Titanium.
- These Drill Bits is unlike any cobalt drill bit and it composes of completely steel alloy with just a coating of Titanium.
- Titanium Drill Bit can easily resist up to 800 degree Celsius
Drilling Mechanism
Cobalt
- Cobalt Drill Bit is efficient to drill stainless steel, cast iron easily.
- The material is heat resistant and it can help the professional to drill for a long time.
- You do not have to use any kind of lubricants while the metal gets heated.
Titanium
- This Drill Bit can easily drill stainless steel, cast iron, and other metals. But they are more preferred on woods or soft metals.
- The friction is low, so it produces low heat. However, for long time usage, the heat may build up strong.
- This one requires cooling lubricants to cool down the body.
Durability Factor
Cobalt
- Cobalt Drill Bits have high friction but this does not reduce the durability of the metal alloy.
- Since it is a mixture of allowing with cobalt, the only way to reduce the lifespan is corrosion.
- Cobalt Drill Bit can easily stay strong for 20 years, but if anyone can bring the sharpness back, it may last for many more years.
Titanium
- The Titanium Drill Bit is composed of high-speed steel body and Titanium Nitrate coating.
- The lifespan completely depends on the coating present. It is not a mixture so once the coating is gone, there is no more of Titanium left.
- These types of Drill Bit has low friction. Thus, it involves high chances of corrosion.
Obviously The Price factor
Cobalt
- The Cobalt Drill Bit is generally far more expensive because of the material itself.
- It composes of 8 percent cobalt which makes the drill bit more expensive to re-gather.
- There are no chances for restoring a Cobalt Drill Bit once the metal is lost.
Titanium
- Titanium Drill Bit is less expensive on the other hand. It is also easily available on the market for better use.
- This Drill Bit has only a Titanium Nitrate Coating. So if it is lost, one can easily treat the product with Titanium coating.
- Refilling Titanium Coating on the drill bit is easy and it cheaply available on the market.
Comparison By Types
Cobalt
- The M35 type of Cobalt Drill Bit is a great option for heavy-duty drilling. It includes 5% cobalt as metal and great for castings and forgings.
- The M42 type of Cobalt Drill Bit includes 8% cobalt in the body. It is specifically designed for machine work and other hard metals. Most of the commercial chambers use such.
Titanium
- The TiN resists friction and it is a Titanium Nitrate Coating on the high-speed steel drill bit.
- The next type is the TiCN or the Titanium Carbo-Nitrate. It is much harder and durable than most other coatings.
- The third type is the AlTiN or the Titanium Aluminum Nitride. This is specifically designed to increase the temperature or resist high heat.
Wrap Up: Better Choice
Both the Cobalt Drill Bit and the Titanium Drill Bits comes with different properties. However, there are different purposes for each of them. If you are looking for professional work for commercial chambers or for regular drilling, you may opt to choose the Cobalt Drill Bit. However, if you are willing to opt for home uses and soft drilling purposes, you can also go for the Titanium Drill Bits. It is a bit cheap and will definitely solve your purpose for drilling metals and soft materials.

Frequently Asked Question [FAQ]
Q1. Will this work with Impact Drill?
Well, I’ve tried this concept not once but a lot of times. For me, all the attempts were successful as I could use the drill set properly. But, while trying for the first time, I felt that using the 1/4 impact along with the drill will work better. So tightening up the nuts and bolts should not be a problem for you.
Q2. Can these be used to drill in concrete?
If you understand the mechanical properties of concrete, you’ll be able to know that the drill is equipped for drilling lightweight material. A friend of mine suggested going for concrete almost two months back. I tried to do it twice and both of the time I faced the same result- the tip is gone! But when I used the Drill Hog 29 Pc Cobalt Drill Bit Set, I must say that I was very convinced.
Q3. Are the bits themselves labeled with the size?
It’s both, yes and no! By this, I mean to say that you won’t get any separate labels with the bits regarding the sizes. So you won’t be able to understand what the size of the bits is. But you can get a size measurement written on the bits holder. So in this way, you can label them manually.
Q4. Can the box be wall mounted?
Of course, they can be. In fact, to mount it, you don’t even have to drill and create a proper loop. You can do this without having nails and hooks. Just get the help of a wall suction tube and it can be enough to mount the box. Mounting the box of bits means that it could get easier for me to work on my garage!
Q5. Can these drill titanium?
Of course, they can and if you want the DEWALT Titanium Drill Bit Set, it is specifically designed for such activities. Moreover, it becomes important that you choose the product wisely as speed is not the key but the bits set are. So you need to make sure that the product you choose must have proper types of equipment.
