What are the strongest drill bits made of?
What is the strongest material for drill bits? If you want to get a seriously powerful drill bit, then opt for carbide. Carbide is considered to be the strongest material that drill bits can be made from, and drill bits made with it are typically used in high-grade, commercial-level projects. However, there’s a caveat with carbide.
What is better high speed steel or cobalt?
High speed cobalt (HSCO) tools are an upgrade from high speed steel (HSS) due to increased heat resistance because of 5-8% Cobalt in an alloy. Cobalt drill bits are better if you need to make a hole in hardened or stainless steel. Drill bits made of carbide (Carb) are the hardest and in the same time most brittle bits.

Is cobalt stronger than titanium?
Hardness: As mentioned in the detailing of cobalt and titanium's scratch resistance, both metals have a similar hardness. But it was noted that cobalt was just a bit harder than titanium. As a result, it is able to have a much higher polish applied.
What is the strongest metal for drill bits?
CarbideCarbide (Carb) is the hardest and most brittle of the drill bit materials. It's used mostly for production drilling where a high-quality tool holder and equipment is used.
Is titanium drill harder than cobalt?
Titanium drill bits are harder than cobalt, but because they are coated, they can't be sharpened. Cobalt drill bits are made of cobalt steel, and they can be sharpened. They are also highly resistant to heat and are very hard and abrasive.
Do cobalt drill bits break easily?
Like other HSS bits, they are corrosion-resistant, which means they should retain their condition in all storage and usage conditions they're likely to experience. However, cobalt can be brittle. If your cobalt drill bits aren't cared for properly or are dropped, they can break – which can prove costly.
What drill bit is stronger than titanium?
Cobalt drill bits are made with a mixture of cobalt and steel alloy. They're usually around 5% to 8% cobalt, with the rest being steel. This makes them extremely tough and able to go through the most rigid materials out there, like cast iron.
What's better than cobalt drill bits?

Can titanium drill bits be sharpened?
If you sharpen a titanium bit its performance will drop because the coating is gone on the tip; however, you still have the benefit of the titanium coating in the flute of the bit and on the sides of the bit. It will still perform better than a standard bit.
What drill bits stay sharp the longest?
Titanium (Coating) This type of drill bit lasts longer than black oxide. Titanium drill bits tend to drill faster than black oxide and chips move through the flutes better. One of the downsides is that the titanium nitride is just a coating and you lose the benefits as the coating wears off the cutting edges.
Is titanium or black oxide better?
I'm sure that you won't be surprised when I say that titanium bits have a significantly longer tool life than black oxide ones. Compared to a bright finish bit, a titanium bit lasts up to 6 times longer. In other words, if you want to get the most value for your money, titanium drill bits are the way to go.

Does cobalt dissipate heat?
All metal-on-metal bits are going to heat up. That is just the nature of rubbing two pieces of metal together very quickly. However, cobalt blades are made to dissipate heat. Cobalt is particularly good at dissipating heat over the contact surface. They can dissipate heat very quickly, even at top speeds.
