One is not necessarily better than all the others, but they each have their pros and cons. Cobalt Drill Bits. Drill bits can be classified in two viewpoints- the size and the materials. This is a great option for drilling into harder steel as well as stainless steel grades. Cobalt is another type of coating for the drill, cobalt drill bit is … The addition of the cobalt allows for the drilling of hardened metals and also stainless steel. Cobalt drill bits are designed for cutting through all sorts of metal, including stainless steel and cast iron. They are also made to drill through tougher materials, like metal. While titanium drill bits wear more slowly, you can sharpen cobalt drill bits again and again. Hardness. Hi there! This can get quite expensive if you’re not careful. Also, cobalt has a higher melting point than steel. The Cobalt bits come in 15-, 19-, 25-, and 29-piece kits while the Titanium set is offered in 10-, 15-, 23-, and 29-piece kits. twist bits: a $2.75 high-speed steel bit, a $6 “black oxide” bit, a $7 cobalt bit and a $9.50 titanium bit. But if you’re working with softer materials more often, titanium drill bits will be the better option. High Speed Steel & Cobalt Drills Speed and Feed Recommendations ...

Basically, there are three types of drill bits in the market-Black Oxide Drill Bits. In general, despite their higher price, cobalt bits tend to provide pretty good value for the cost – mostly because you can use them for so long. Hopefully this article has helped you narrow down your choice of the best drill bits for your job. High-speed steel is alloyed with 5-8% cobalt to create cobalt drill bits. Because of this, they can often save you money in the long run. ; Aluminum, brass or copper: Choose an all-purpose bit … Range of coatings means you can use titanium drill bits for both hard and soft materials. Instead, they are made of an alloy of high-speed steel and cobalt. The result is a drill bit capable of withstanding extremely high drilling temperatures. That said, they’re still more versatile than a standard HSS drill bit. However, there are a few slight differences that set them apart from their Cobalt cousins – though both do look very similar at first. When you sharpen titanium drill bits, this coating comes off as well. These Drill Bits is unlike any cobalt drill bit and it composes of completely steel alloy with just a coating of Titanium. © 2020 ToolToAction, All rights reserved. Cobalt and titanium don’t act quite the same, so cobalt and titanium coatings can make your drill bits behave differently from one another. It depends on whether you want to spend more money now or later. The downside of this type of drill bit is that the cobalt and steel alloy coating makes it a bit brittle. Remember they belong to the HSS drill bit class. Sharpening them would therefore expose the steel core, rendering them nearly useless. The Main Differences Titanium Drill Bits vs Cobalt Drill Bits The Main Differences Titanium Drill Bits vs Cobalt Drill Bits are: Titanium Drill Bits are made of steel and coated with either titanium nitride or titanium carbonitride, whereas the Cobalt Drill Bits are made from a mixture of cobalt and steel alloy. ; Cast iron: Choose a cobalt bit with a 135-degree flute.

As we said, neither of these drill bits is necessarily always going to be the best choice. Because the cobalt is alloyed with the steel rather than just a coating, you don’t risk losing any of the enhanced material properties by sharpening the drill bit. If you work with a wide variety of materials, you probably want a set of cobalt bits. They’re most commonly used to cut through hardened materials that steel alone would struggle with. There’s little point using an expensive drill bit for soft materials when a cheaper alternative would do the job as well. Importantly, a higher melting point means the cutting edge is more resistant to the heat generated by cutting. Cobalt drill bits are a combination of a base alloy (usually steel) and a small amount of cobalt. As mentioned, the main advantage of cobalt bits over something like HSS (high speed steel) is the improved heat resistance. Instead, they have a metal core and a titanium coating.

Light metals, including sheet metal: Choose a 135-degree flute bit made from any material but cobalt.A 118-degree bit works in a pinch. I have a great passion for writing about everything related to tools, home improvement, and DIY. In contrast, the cobalt bits are made of cobalt and steel alloy. Hard wood, particularly if it’s full of knots. The differences start from the production of the bits. Titanium drill bits have a wide range of uses over standard HSS bits. Cobalt bits have a wide range of practical uses compared to standard HSS drill bits. Popular for their tough design, cobalt drill bits are formed by alloying 5-8% cobalt with high-speed steel. To begin with, cobalt has a high resistance to massive heat. I’ve covered all the important information about titanium drill bits, but here’s a summary of the pros and cons for convenience. However, the melting point isn’t as high as cobalt, so they’re often not as durable. Titanium Drill Bits. Over the life of the bit, however, the extra initial cost of the cobalt drill bit evens out. My name is Adam and I write for HealthyHandyman. In this article I’ll look at the differences of cobalt and titanium drill bits, including their most suitable uses. Cobalt bits are quite a bit more expensive than titanium ones. Most drill bits out there designed for tougher materials have some design feature that is made to dissipate heat. Harder materials wear the bit down faster by removing the coating faster. Don’t last as long as cobalt if used regularly. The material with which the drill bit is made is an essential point of difference. Cobalt is particularly good at dissipating heat over the contact surface. They’re usually around 5% to 8% cobalt, with the rest being steel. Cobalt drill bits are made of steel and cobalt while titanium drill bits are made of high-speed steel and titanium nitride. With that said, titanium bits are best for wood and softer metals. Their better quality materials and ability to be sharpened means they’ll last you a lot longer than a standard HSS drill bit. You can read more about the topic in my article comparing black oxide, cobalt, and titanium drill bits. This is because, unlike cobalt drill bits, titanium bits are only coated. This makes them extremely tough and able to go through the most rigid materials out there, like cast iron. Black Oxide Vs Titanium Vs Cobalt: Differences 1. When the coating is completely gone, the bit would have lost much of its heat resistance. So, what is high-speed steel? If you have the funds and the patience to sharpen drill bits by yourself, we recommend going with cobalt drill bits. Yes, you can, but it will be an overkill.
