        The Three Main Types Of Carbide Drills

        Carbide drills sound boring, but for DIY enthusiasts or commercial contractors, the type of bits used in the project is as important as the project itself.

        There are many kinds of drills, not only cemented carbide drills, but also steel bits, brick and stone bits and wood bits. In this article, I will explain the basic principle of steel bits and different types of drills.

        The first kind of bit is steel bit

        Steel drills are the cheapest in this range because they are used for very basic applications such as plastics and cork. This kind of bit is not suitable for any other application because its service life is very short and it is easy to break when it keeps sharp enough to continue working. Basically, in this case, you will get what you pay for.

        The second type of bit is coated bit

        In this case, the drill manufacturer produces steel drills and then coats them with tungsten carbide coating, one of the hardest coatings on the market, which allows the drill to stay sharper for longer and allows you to handle more challenging projects, such as hardwood and thin metal.

        The third bit is tungsten carbide bit

        Cemented carbide bits are the best on the market. They are made of the hardest carbon and minerals and can be used in almost every application area, from super wood to heavy metals. They are much more expensive than other bits, but because they have a longer life, they are actually cheaper than other bits
