![]() ![]() They are generally made from HSS and are suited to general household DIY tasks, as well as professional applications like maintenance and engineering.Masonry – The TCT drill bits are the best to use when drilling brick, block, stone and mortar and are most commonly used in the construction industry. TiN coated drill bits are best suited for drilling more stubborn materials like iron, steel, aluminium and more.Common types of drill bitsTwist – The most common type of drill bit and ideal for drilling wood, plastic, and metals. It is a more expensive coating than others but helps to increase production rates and tool life. It can also be used with black oxide to better identify higher grades of HSS.Titanium Nitrate – This coating increases the hardness of the bit, whilst providing a thermal barrier for high friction applications. It is normally used on its own so that it is easy to identify cobalt steel. It also helps in retaining drilling lubricants for longer and is most suitable when drilling iron and steel.Bronze Oxide – This coating increases the stress relieving of the bit. Carbon steel can withstand higher temperatures and is more suitable for harder materials.HSS (High-Speed Steel) – HSS can withstand higher temperatures without compromising the hardness of the bit and is able to cut faster with more accuracy and efficiency.Cobalt Steel – The cobalt content increases the strength of the bit and aids in the resistance to heat and friction, so it can be used for more stubborn materials.Tool Steel with Tungsten Carbide Tips – TCT provides a longer working life for the bit while allowing for a more stable and solid tip and enabling it to withstand more rigorous drilling applications.What coatings are used to enhance drill bits?Black Oxide – An economical coating that prevents corrosion and increases stress relieving at the bit. Learn more in our complete guide to drill bit sets.What materials are used for drill bits?Carbon Steel – This material provides a drill bit with better durability and hardness, therefore increasing the life of the bit. Having the right size and the right type of bit is key in ensuring the highest standard of work and ensuring that you can drill with confidence and accuracy. If you are looking for more than one type drill for your workbench, consider investing in a combo kit that offers a standard power drill, a specialty drill, a charger, batteries and carrying case.Drill Bit Sets Drill bits are cutting tools that are used to remove material in a piece to create a circular hole. Should your DIY projects require high-level usage and maximum performance, consider a drill with a brushless motor. If you use the wrong drill bit, your drill will have to work harder and may provide subpar results.īrushless motor drills offer more torque and a longer lifespan than standard power drills. Wood, metal, plastic and masonry each require different types of drill bits. To ensure your drill delivers the ultimate performance, pair it with the right drill bit for the material you are using. Electric screwdrivers also speed up the process of driving screws in and out of various materials. They are primarily used for drilling into concrete, stone and masonry. Specialty drills include hammer drills, impact drivers and rotary drills. The most common are drilling holes and driving screws Handheld power drills can perform a variety of tasks. Cordless drills offer unlimited range and maximum power with a fully charged battery and are available in 12-, 18- and 20-volts. Some electric drills have power cords and require an electrical outlet and steady supply of electricity for proper operation. Drills are key power tool staples for every DIYer and homeowner. ![]()
