If you work in an industry that relies on tools to get the job done, you’ll already know just how important a drill is for your overall success. But what you may not know is that the drill bit is arguably just as important. You may have a top-quality drill, but if the drill bit is subpar, then your work will suffer. Fortunately, that’s not a problem that you need to deal with. Armed with the correct information, you can ensure that you always have a drill bit that’ll aid, rather than hinder your project. So what’s the best option? Most experts agree that carbide drill bits are the way to go. We’ve put together a handy carbide drill bits buying guide, so you can know exactly what piece you need for the job.

1. What are Carbide Drill Bits?
Let’s begin by looking at what a carbide drill bit is. ‘Carbide’ refers to the material that the drill bit is made from. There are plenty of different drill bit materials, but they’re not all appropriate for all jobs. The most common option is the HSS drill bit, which will likely have been the drill bit you used if you completed a home DIY project. They’re handy and effective, but only in certain situations; you typically won’t find HSS drill bits used in industrial settings.Industrial jobs typically used carbide drill bits because of their strength. They’re made from a mixture of tungsten and carbon, two very strong materials that combine to create a drill bit that can cut through items that would break an HSS drill bit, such as concrete, tile, and others.
2. Carbide Drill Bits Constructions
You don’t have to look at a carbide drill bit for too long before you notice that they’re not quite the same as other drill bits you may have come across. That’s because the way they function is slightly different to drill bits made of other materials. Carbide drill bits are used to drill holes in hard materials, and they do this by punching the material until it is crushed. The bit moves up and down repeatedly (at a rate too fast for the eye to see) and, in the process, transfers the debris of the punched hole outside.You can get carbide drill bits cut into a specific shape, custom-made for the intended use, but there are also plenty of standard options available, too — for example, twist, spade, hole saw, and step bit. It’s important to remember that carbide largely just refers to the material; if you see any drill shape, it’ll probably be available in carbide. You can also get carbide drill bits in virtually any size, anywhere from a few inches all the way to sixty inches. If you need a greater length than that, you can get one custom-made — there’s no limit to how long the bits can be.

4. Advantage of Carbide Drill Bits.
We’ve spoken a lot about the various kinds of carbide drill bits available. Now the question is why they’re worth your money. After all, there are plenty of different drill bits available. So what is it that makes these ones stand out from the crowd? Let’s take a look at some of the many advantages that they offer.-
They’re Strong
-
They Offer Excellent Precision
-
They’re Long Lasting
-
They’re Versatile
They’re Good For The Environment
We’ve already said that it’s hard to destroy carbide drill bits — and that’s an excellent attribute in relation to the environment! The majority of drill bits are made using recycled materials, and once the drill bit has reached the end of its life, it’ll likely be used to make other products, too.
5. Applications of Carbide Drill Bits
You’ll find carbide drill bits being used in a wide range of industries. They’re generally not used in domestic projects because they’re not needed. But they’re a mainstay in tool cutting, PCB manufacturing, woodwork, gas and oil projects, and masonry. Essentially, you’ll find carbide drill bits in any industry when strength and/or precision drilling is required. In PCB manufacturing, for example, they’re used for accurately drilling in small sizes; in oil and gas projects, they’re used to drill through some of the earth’s hardest materials; in masonry, they’re used to drill through concrete and brick.6.
