Here's a review and comparison of the Harbor Freight warrior machinist 115 piece drill index sets jobber lengths. Cobalt vs Titanium Drill Bits – 2020 Review Learning proper use of tools is a handy investment. Only using them every now and then for at-home jobs it’ll take quite a while to wear down the coating. However, this coating does wear down over time. This means, the bits work with high-speed drills and pin at top speeds while powering through hard materials like metals without losing their … Popular for their tough design, cobalt drill bits are formed by alloying 5-8% cobalt with high-speed steel. © Copyright 2021 HealthyHandyman. When choosing the right titanium drill bit, consider the material you’re drilling. But if you’re working with softer materials more often, titanium drill bits will be the better option. The Pros and Cons of Cobalt Bits Titanium drill bits are capable of coping with heat since their titanium coatings enhance the dissipation of heat buildup more effectively compared to most drill bits, but they are quite expensive and don’t have the durability of cobalt 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. They are best for professionals, though DIYers, with lots of projects, will appreciate them as well. Cobalt bits are specifically designed for drilling very hard, abrasive materials such as treated stainless steel, titanium and cast iron. All in all, both of these bits dissipate heat well and can handle tougher materials. Yes, you can, but it will be an overkill. This can get quite expensive if you’re not careful. Cobalt drill bits can be sharpened many times over and far outlast a titanium coated drill. This will happen much faster if you’re only using the bits on hard materials. Of course, this is assuming that you have a bit of money to spend upfront. You can sharpen cobalt bits many times before they become unusable. Cobalt drill bits are designed for cutting through all sorts of metal, including stainless steel and cast iron. Can be used in both hand and drill presses. You should save your cobalt drill bits for jobs where they out-perform less expensive alternatives. It contains all the information you might need for a range of types. But this coating will still wear off over time even without sharpening. If you’ll use them regularly for hard materials, then I’d recommend a good set of cobalt drill bits. Also, cobalt has a higher melting point than steel. Learn more. When you buy via links on our site, we may earn an affiliate commission at no cost to you.

This makes them extremely tough and able to go through the most rigid materials out there, like cast iron. Best Cobalt Drill Bit Set – Drill Hog. High-speed steel is alloyed with 5-8% cobalt to create cobalt drill bits. Hopefully this article has helped you narrow down your choice of the best drill bits for your job. The cobalt also prevents the bit from getting too hot as it spins against other metals. The greater heat resistance means the drill bits will remain sharper for longer. Cobalt has many advantages that will be useful in the work. Importantly, a higher melting point means the cutting edge is more resistant to the heat generated by cutting. ; Aluminum, brass or copper: Choose an all-purpose bit … Yes, drill bits do not end with titanium and black oxide bits. When you sharpen titanium drill bits, this coating comes off as well. Over time, this coating will wear off. Ability to sharpen them extends drill bit’s life. Over the life of the bit, however, the extra initial cost of the cobalt drill bit evens out. 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. Cobalt Drill Bits. twist bits: a $2.75 high-speed steel bit, a $6 “black oxide” bit, a $7 cobalt bit and a $9.50 titanium bit. Less expensive than cobalt drill bits – good for home DIYers. Once again, neither of these drill bits is better than the other. Instead, they have a metal core and a titanium coating. I have a great passion for writing about everything related to tools, home improvement, and DIY. Cobalt and titanium drill bits have a few things in common and in most cases, are used for similar applications. Cobalt drill bits are a mix of metals plus either 5% cobalt (M35 drill bits) or 8% cobalt (M42 drill bits). Although 8% cobalt drill bits will drill harder metals than 5% cobalt drill bits it is important to note that the additional cobalt … 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. Black Oxide Vs Titanium Vs Cobalt: Differences 1. Titanium drill bits have a wide range of uses over standard HSS bits. While titanium is a pretty hard material, titanium drill bits are only coated with a thin layer of titanium nitride, which erodes quickly. As we said, neither of these drill bits is necessarily always going to be the best choice. A: Cobalt steel drill bits are ideal for use with hard metals, like cast iron or stainless steel, because they can be sharpened and have high heat resistance. Cobalt bits tend to be quite expensive. My name is Adam and I write for HealthyHandyman. The material with which the drill bit is made is an essential point of difference. Two of the best materials you can turn to are cobalt and titanium.

Cobalt vs titanium drill bits possess the resilience needed and won’t break or warp when making holes and drilling screws through the material. This titanium is essential for preventing overheating, as we discuss below. With harder materials, they will need more frequent sharpening, which can wear their coating down quickly. Sharpening them would therefore expose the steel core, rendering them nearly useless. You’ll definitely get your money’s worth over time. Harder materials wear the bit down faster by removing the coating faster. Their better quality materials and ability to be sharpened means they’ll last you a lot longer than a standard HSS drill bit. Titanium drill bits are also good in metal cutting machines because they can be used to drill very precise holes. This coating protects the metal core from the heat and dissipates it along the surface. One is not necessarily better than all the others, but they each have their pros and cons. That said, they’re still more versatile than a standard HSS drill bit. This drill bit is made out of an alloy of titanium nitride and high-speed steel.

These Drill Bits is unlike any cobalt drill bit and it composes of completely steel alloy with just a coating of Titanium. Cobalt bits are pretty easy to sharpen. While they’re very hard they’re also very brittle and can shatter easily. However, there are a few slight differences that set them apart from their Cobalt cousins – though both do look very similar at first. Can’t be sharpened, meaning you’ll have to replace them once coating wears off. Drilling with dull bits slows the process and causes overheating. Cobalt bits was doped with 5 or 8 percent cobalt. However, they don’t last as long because the coating comes off over time. And the advantage of titanium over cobalt is the initial price. So, what is high-speed steel? By doing simple and easy tasks around your home, you can not only become proficient in skills that will come in handy in life, but you can also save money by avoiding paying someone to perform these tasks for you. For example, you’ll want to use a titanium carbonitride bit for harder materials, but you’ll be fine using titanium nitride for wood or plastic. Basically, it’s just another type of steel. The result is a drill bit capable of withstanding extremely high drilling temperatures. Cobalt bits have no coating at all, which differs from titanium drill bits.
