It contains all the information you might need for a range of types. Of course, some people don’t need a durable bit that is going to last a long time. The downside to cobalt bits is that they tend to cost a bit more than their steel counterparts. With that said, titanium bits are best for wood and softer metals. But if you’re working with softer materials more often, titanium drill bits will be the better option. One is not necessarily better than all the others, but they each have their pros and cons. They’re very tough bits, making them suitable when others just won’t do. They’re most commonly used to cut through hardened materials that steel alone would struggle with. One thing to consider is that cobalt bits are quite brittle. Their better quality materials and ability to be sharpened means they’ll last you a lot longer than a standard HSS drill bit. In my spare time, I'm either fishing, playing the guitar, or spending quality time with my beloved wife. The addition of the cobalt allows for the drilling of hardened metals and also stainless steel. Cobalt drill bits can be sharpened many times over and far outlast a titanium coated drill. Learn more. Although 8% cobalt drill bits will drill harder metals than 5% cobalt drill bits it is important to note that the additional cobalt … You’ll see a wide range of different drill bits out there. The cobalt also prevents the bit from getting too hot as it spins against other metals. Despite their primary use for metal, they can also be used for softer materials. Cobalt bits are not designed for general purpose use. They do not have a coating, so there is no surface stripping when sharpening them. When you sharpen titanium drill bits, this coating comes off as well. Only using them every now and then for at-home jobs it’ll take quite a while to wear down the coating. 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. The Milwaukee Cobalt Red Helix Drill Bits performed flawlessly. I’ve covered all the important information about titanium drill bits, but here’s a summary of the pros and cons for convenience. And the advantage of titanium over cobalt is the initial price. What are cobalt drill bits used for? Although I’d always advise using coolant when drilling metal, it’ll always make them last longer. So, what is high-speed steel? High-speed steel is alloyed with 5-8% cobalt to create cobalt drill bits. Cobalt bits tend to be quite expensive. You’ll definitely get your money’s worth over time. To begin with, cobalt has a high resistance to massive heat. If you’ll use them regularly for hard materials, then I’d recommend a good set of cobalt drill bits.

Can’t be sharpened, meaning you’ll have to replace them once coating wears off. They are better suited for drilling metal due to high resistance to the massive heat generated when drilling through highly abrasive and/or hard materials such as treated stainless steel, titanium, and cast iron. There are also cobalt bits and high-speed bits. When it comes to cobalt vs. titanium drill bits, the main advantage is that the cobalt is alloyed into the bit rather than applied as a coating. If you work with a wide variety of materials, you probably want a set of cobalt bits. Instead, cobalt drill bits are generally made from high-speed steel which contains a certain percentage, usually 5% to 8% of cobalt. I can drill maybe 3 holes and the bit is still comfortable enough to hold, couldn't do that with the titanium bit and it cuts cleaner and quicker. However, there are a few slight differences that set them apart from their Cobalt cousins – though both do look very similar at first. As an Amazon Associate I earn from qualifying purchases. Titanium drill bits are also good in metal cutting machines because they can be used to drill very precise holes. Remember they belong to the HSS drill bit class. Hard wood, particularly if it’s full of knots. It depends on whether you want to spend more money now or later. This allows you to work on harder materials, like stainless steel and cast iron, without damaging your equipment. You'll also often find me in my workshop working on some new project! There’s little point using an expensive drill bit for soft materials when a cheaper alternative would do the job as well. The differences stem from the way these drill bits are made. Cobalt bits was doped with 5 or 8 percent cobalt. Healthyhandyman is reader-supported. My name is Adam and I write for HealthyHandyman. Sliding vs Non-Sliding Miter Saw – Which Is Best for Me?
