When it comes to choosing the right drill bit for your project, there are a lot of factors to consider. Do you want a bit that is durable and long-lasting? Or perhaps one that can cut through metal quickly?
In this article, we will compare black oxide drill bits, titanium drill bits, and cobalt drill bits to help you decide which is best for your needs.
Black Oxide Drill Bits
When it comes to drill bits, there are a lot of different materials that they can be made from. Depending on the project you’re working on, one type of drill bit may be better suited than another.
Black oxide drill bits are made from high-speed steel that is coated with black oxide. This makes the drill bit more resistant to wear and less likely to break or chip. Black oxide drill bits are best used for drilling in soft materials, such as wood or plastic.
While black oxide drill bits are less likely to break or chip, they are not as heat resistant as other types of drill bits. Because of this, they should not be used for drilling in metals or any other hard materials. [1]

Black Oxide vs. Titanium vs. Cobalt Drill Bits
Quality
There are three main grades of the drill bit on the market today: black oxide, titanium, and cobalt. Which one is best for your project? It depends on what you’re drilling and how often you plan to do it.
Black oxide bits are the most common type of drill bit. They’re made of high-speed steel (HSS) and coated with black oxide. HSS is a durable material that can withstand high temperatures, making it ideal for drilling into metal.
Titanium drill bits are made of HSS that’s been coated with titanium. Titanium is a harder metal than HSS, so it can stay sharp longer. It’s also less likely to break or chip.
Cobalt drill bits are made of HSS that’s been coated with cobalt. Cobalt is a harder metal than titanium, so it can stay sharp even longer. It’s also less likely to break or chip. [1]
Performance
The main difference between black oxide, titanium, and cobalt drill bits is their performance.
Black oxide bits are the most common type of drill bit and they’re good for general drilling. Titanium drill bits are better for drilling into hard materials, and cobalt drill bits are the best for drilling into extremely hard materials.
There are different drill bits for different materials. Black oxide bits can be used for drilling into wood, plastic, and metal. Titanium drill bits are better for drilling into hardwoods, metals, and stainless steel. Cobalt drill bits are the best for drilling into cast iron, hardened steel, titanium, and other difficult-to-drill materials.
Cost
The cost of black oxide, titanium, and cobalt drill bits varies depending on the size and quality of the bit. Black oxide bits are the most common type of drill bit and they’re usually the least expensive.
Titanium drill bits are more expensive than black oxide bits, but they’re still less expensive than cobalt drill bits. Cobalt drill bits are the most expensive type of drill bit.
There are three types of drill bits- black oxide, titanium, and cobalt. They each have their own advantages and disadvantages. It is important to choose the right type of drill bit for your project.
Consider what material you will be drilling, how hard the material is, the size of the hole you need to drill, and how much the drill bit costs. With so many factors to consider, it is important to do your research before making a purchase. With the right drill bit, you can complete your project quickly and easily.
Black oxide drill bits are the most affordable option of the three, costing an average of $ 0.03 per drill bit. Titanium drill bits are more expensive, averaging around $ 0.05 per drill bit. Cobalt drill bits are the most expensive option, averaging about $ 0.08 per drill bit. [1]
Hardness
Black oxide drill bits are made of high-speed steel (HSS), which is a type of steel that contains carbon. HSS is strong and can withstand high temperatures, but it is not as hard as cobalt or titanium.
Titanium drill bits are made of a steel alloy that contains titanium. Titanium is harder than HSS, but not as hard as cobalt.
Cobalt drill bits are made of a steel alloy that contains cobalt. Cobalt is the hardest of the three materials, making it the best choice for drilling through tough materials.
Material
Differences:
There are three types of metal-based drill bits: black oxide, titanium, and cobalt. They each have their own unique benefits that make them good for different types of projects. Let’s take a closer look at each type to see what makes it special.
Black Oxide:
Black oxide drill bits are made of high-speed steel that has been coated with a black oxide finish. This finish not only gives the bit a sleek appearance but also helps to protect the bit from corrosion and wear. The black oxide coating also helps to dissipate heat, which keeps the bit cooler during use.
Titanium:
Titanium drill bits are made of high-speed steel that has been coated with a titanium nitride finish. This finish is extremely durable and helps to protect the bit from wear. Titanium drill bits also have a tendency to run cooler than other types of bits, which helps to extend their life.
Cobalt:
Cobalt drill bits are made of high-speed steel that has been coated with a cobalt alloy. This coating helps to improve the bit’s wear resistance and heat dissipation. Cobalt drill bits are also designed to be used in high-temperature applications.
Lifespan
Purpose
Black oxide drill bits are used for a variety of purposes. They are most commonly used for drilling through metal, but can also be used for other materials such as wood and plastic.
Black oxide drill bits are designed to be more durable than standard drill bits and can withstand more wear and tear. This makes them ideal for use in high-speed drilling applications.
Black oxide drill bits are also more resistant to corrosion than standard drill bits. This is due to the black oxide coating that is applied to the bit. The black oxide coating helps to protect the bit from rust and other corrosion that can occur during use.
Durability
One of the most important factors to consider when choosing a drill bit is durability. All three materials are quite durable, but there are some key differences to keep in mind.
Black oxide is the most affordable option and is typically used for general-purpose drilling in wood and soft metals. Titanium bits are more expensive, but they offer better heat and wear resistance. Cobalt bits are the most expensive but offer the best heat and wear resistance of the three options.
Speed
Another important factor to consider is speed. Black oxide bits are the slowest of the three, but they’re still fast enough for most general-purpose drilling applications. Titanium and cobalt bits are both faster, but cobalt bits are the fastest of the three.
Wear Resistance
Titanium and cobalt drill bits offer superior wear resistance when compared to black oxide drill bits. This is due to the fact that titanium and cobalt are much harder metals than black oxide.
This means that they will retain their sharpness for longer, and will be able to drill through tougher materials without dulling as quickly.
Heat Resistance
Titanium and cobalt drill bits offer superior heat resistance when compared to black oxide drill bits. This is due to the fact that titanium and cobalt are much better at dissipating heat than black oxide.
This means that they will be less likely to overheat and cause damage to your workpiece, and will also be able to drill through tougher materials without issue.
Color
Titanium and cobalt drill bits will both typically be silver in color. Black oxide drill bits, on the other hand, will be black in color.
This is due to the fact that black oxide is a coating that is applied to the metal, whereas titanium and cobalt are the metals themselves.
Similarities
All three types of drill bits are made from high-speed steel (HSS), which is a form of tool steel that can be hardened and tempered to create various levels of hardness. HSS is known for its durability and resistance to wear, making it an ideal material for drill bits.
Black oxide, titanium, and cobalt drill bits all have a coating that helps to extend the life of the bit by preventing wear and tear. The main difference between these coatings is the material that they are made from.
Black oxide is the most common type of drill bit coating. It is created by combining iron with oxygen to create a black film on the surface of the drill bit. This film helps to protect the drill bit from rust and corrosion while also reducing friction.
Titanium drill bits have a coating made from titanium nitride. This helps to increase the hardness of the drill bit, making it less likely to wear down over time. Titanium drill bits are also more resistant to heat than black oxide or cobalt drill bits.
Cobalt drill bits have a coating that is made from cobalt chromium. This coating makes the drill bit harder so it does not wear down as quickly. Cobalt drill bits are also more resistant to heat than black oxide or titanium drill bits. [2]
Useful Tips:
- Black oxide bits are good for general drilling into wood, plastic, and metal;
