The counterbore drills a hole of the same length as the screw upto the screw head. Counterbore Drill BitsĬounterbore drill bits are used for enlarging an already existing hole to make the screw stand firmly at its position. They are mostly known to be great performers when cutting metal.Ĭheck out one of my favorites here. These bits can do a great job drilling through wood, plastic, steel, and even concrete. Twist bits are one of the most used drill bits out there as anyone can utilize them, be it a regular craftsperson or a professional. 25 Different Types of Drill Bits and Their Uses 1.
Although they are exceptional performers, you will still have to think twice before purchasing as these cost a lot.
Diamondĭiamond bits coating will prove a fantastic choice if you drill on hard materials such as glass, tile, or metals. Ultimately, the flow of material will also improve. Black Oxideīlack oxide coating will minimize the friction while cutting, which will prevent the extreme heat up in the drill bit. It is also essential to provide a heat build-up solution and let little friction occur. These bits will stay flexible for more time than the other bits because of their high durability. TiN provides a variety of speed ranges to work with. Coatings of Drill BitsĪfter discussing the materials, now comes the coatings of the drill bits, which is another way of distinguishing between certain kinds of drill bits. The carbide-tipped drill bits can help drill to tile, masonry, and other hardened materials. So, to reduce the market price, the bits are only tipped with carbide. It is because carbide is one of the most rigid materials, and it costs just as much. The only difference is that these are not wholly produced by carbide except for their tips. These drill bits are somewhat similar to the solid carbide bits as they are also made out of carbide. These drill bits are entirely made from solid carbide, which is the crucial point here. Solid carbide drill bits will prove a perfect fit for stiff materials. It can resist a tremendous amount of heat which is why it stands perfect on any surface of any resistance. CobaltĬobalt drill bits are specially designed to drill hard and stiff materials like stainless steel and other rigid substances such as cast iron or titanium. You can use high-speed steel for wood, iron, and other metals like brass and aluminum. It is specifically designed to handle the rising temperature and allow the drilling process to occur at higher temperatures. High-speed steel is well known for drilling into hard surfaces because of its wear resistance and increased hardness. They also come with finer durability than low carbon and are more favored. These have better reliability and require little maintenance. These are relatively cheaper but require good maintenance.Īt the same time, high carbon steel will be best for cutting into woods and metals. You can use low-carbon steel to cut or drill into softwood and plastics. The two kinds of carbon steel, both high and low, can work differently. Suppose you want low or no heat generated while drilling carbon steel might be a good choice for you. Here are some materials that you should know before purchasing a suitable drill bit Carbon Steel The suitable material will save a lot of your time, energy, and money for sure! You would come across many different drill bits with other purposes, so there is no hindrance while completing a task. The material of a drill bit plays a major role in making sure that you are working with as much efficiency as possible. Choose the Best Wood Boring Bits For The Job
