Whether you’re renovating a client’s house, simply refurbishing your own home, or working on a DIY project, a good drill bit is the need of the hour. 

Drill bits come in a variety of sizes and shapes for use in construction projects and DIY works. For dealing with metals or other such tough materials, you need a good drill bit. A standard drill bit will not perform as efficiently as you will want it to. 

While cobalt drill bits can efficiently cut through abrasive metals, titanium bits are sturdy enough to cut through any metal, including metal sheeting. Cobalt bits are also highly durable and can even withstand hot temperatures. On the other hand, titanium bitscan drill like the wind and are ideal for general drilling purposes. 

Without further ado, let’s hop on to the deets of the two. 

What Are Cobalt Drill Bits?

If you are on the lookout for drilling hard and abrasive materials, then cobalt ones are the perfect option for you to consider. 

Featuring about 5 - 8% cobalt, this is a highly efficient drill bit. As it’s made of steel along with cobalt, it is sturdy enough to last almost a lifetime. Also, its high-speed steel (HSS) is what makes this drill durable. And because of this cobalt bits are resistant to a variety of uses and damages. 

Why Prefer Cobalt Drill Bits?

Cobalt drill bits can easily drill through metals which standard drill bits fail to penetrate. Furthermore, because they are robustly built and are resilient enough, they will not wear down quickly. But, you can also sharpen them from time to time and use them for as long as you want. 

Also unique is its gold color, which lets you spot this tool even amidst the pool of your tools. Drilling requires sturdy bits, and these bits can withstand up to 1,100 degrees Fahrenheit. As such, you do not need to worry as this bit won’t shatter or break while working against other metals, thanks to its high resistance to heat. 

These drills are ideal for all kinds of usage, thanks to their versatility. Be it commercial, engineering, home, or any DIY projects, you can easily use these drill bits to complete your task without a hitch.

And because they are highly versatile, you can use them on cast iron, stainless steel, and any other material. You can also use them on soft materials but must be cautious while working, so as to ensure that you don’t damage the work material. 

What Are Cobalt Drill Bits Good For?

Cobalt drill bits have a number of advantages that make them stand out from other drill bits. 

  1. Durability

What Are Titanium Drill Bits?

Made up of steel with a titanium coating, you would find titanium bits in different forms. They are capable of resisting high temperatures, thanks to their strong, heat-resistant Titanium Nitride coating (TiN).

Apart from this, you can even find them in titanium aluminum nitride (TiAN), and titanium carbonitride coating (TiCN). A TiAN coating can effectively double or triple the span of your drill bits, while TiCN is strong and sturdy and performs efficiently in appliances that are subjected to a lot of mechanical stress.

Why Prefer Titanium Drill Bits?

Titanium drill bits can withstand temperatures of up to 1500 degrees Fahrenheit, thanks to their toughened coating, which acts as a protective wall between different metals. Because of their durable coating, they can drill through tough materials efficiently. If you are looking for an extremely robust and long-lasting drill bit, then this is an ideal option for you to consider. 

These bits are highly versatile. They can easily and quickly drill through those toughened surfaces, which are difficult to penetrate with the regular drill bits. The titanium bits are an excellent choice for drilling into toughened woods.

Cobalt vs. Titanium Drill Bits- How To Choose Between The Two?

Be it DIY, construction, or any other project, drill bits have become a necessity for all those complex drilling work. Both titanium and cobalt variants are strong, sturdy, and durable. But how do you choose between the two?

To answer this question effectively, let’s explore the features of the two drill bits to help you understand how to make a better choice.

  1. Uses

Both the cobalt and the titanium bits perform exceptionally well for drilling through materials. However, they are designed to cater to different drilling purposes. 

If your next project involves dealing with hard and abrasive materials, then cobalt ones are excellent. They can drill through such materials effortlessly and efficiently. Be it stainless steel, cast iron, or any such hard materials; you’re good to go with cobalt drill bits.

On the contrary, titanium bits are perfect for drilling through soft materials because of their titanium coating. If you are a DIY person and have drilling projects at hand, then this type is excellent for meeting all your drilling needs. Soft metals, wood, plastics, or any such materials - you can complete all the tasks in a breeze with this drill.

  1. Composition

Both the cobalt and the titanium variants are composed of different materials. A combination of steel and cobalt alloy goes into the making of the former kind of drill bits. And the cobalt alloy is what makes them highly efficient.

On the other hand, titanium bits are composed of high-speed steel along with a layer of titanium nitride on the exterior. And this is what makes them strong and resistant to damage. 

  1. Durability

Cobalt bits are robustly built to last long. And, if you take proper care of these bits, they can last for more than 20 years. Also, if you keep sharpening them, you can make them last a few years more. So, if you are a professional in quest of robust and sturdy drill bits, your search ends here.

On the flip side, titanium variants are not as durable as cobalt drill bits, mainly because of their titanium coating. But, it is this titanium coating that makes it resistant to heat and ensures superior performance as compared to other drill bits. It is highly durable than the regular drill bits available on the market. 

  1. Sharpening Of The Bits

The good news is that the cobalt drill bits can be sharpened over time. In case you notice the drill bits getting blunt due to heavy usage, you can sharpen it with a drill bit sharpener. This ensures that the drill will last long. 

However, titanium bits can’t be sharpened. But, this does not mean they are lower in quality than cobalt drill bits. The drill bits with Titanium Aluminum Nitride (TiAN) coating extends the life of the drills four or five times as compared to those with regular titanium coating. Thus, they don’t need to be sharpened. 

  1. Types

Cobalt drill bits come in 2 variants. Featuring 5% of cobalt alloy, the M35 drill bit is an excellent handheld drill. This will allow you to work efficiently and will also last longer. At the same time, the M42 contains 8% of cobalt and can withstand high temperatures. 

The titanium drill bit comes in 3 varieties. You can go for the one coated with Titanium Nitride (TiN) if you are looking for a drill with resistance to higher temperatures. But, if you want a long-lasting drill, then nothing can surpass the one with Titanium Aluminum Nitride (TiAN). 

However, there’s a third variety too that can withstand significant mechanical stress, and that is the one coated with Titanium Carbonitride (TiCN). If you are a professional looking for a drill that can perform impeccably with abrasive materials, then just go for this one. 

  1. Price

Well, the prices of both the drill bits vary, for both of them are designed for different needs. Because of their durability, resistance, and versatility, cobalt drill bits fall slightly on the expensive side. 

On the flip side, the titanium bits come with a friendly price tag. They, too, are durable, can withstand high temperatures, and can last for years.  

So, if you are a professional or a contractor looking for a drill that will last you almost a lifetime, then nothing is better than cobalt. But, if you are just a beginner venturing into the drilling field or a DIYer, then titanium ones are the best for you. They perform drilling jobs impeccably and are also easy on your pocketbook.
