How to find the right drill bit for your job?

Drill bits help you in getting the most out of your tools. They are made up of different materials, and each drill bit is meant to serve a different purpose. For specific tooling requirements, it is necessary to select the right drill bit which is curated for the task. Understanding different types of drill bits, materials used to make them and design variation is, therefore, significant in making informed decisions while choosing the right drill bit for your job.

  • Drill bit materials: High-Speed Steel (HSS), Cobalt(HSCO)and Carbide are used to create drill bits. Each one of them caters to different requirements.
  1. High-Speed Steel (HSS): Drill bits made of high-speed steel are used to drill into soft steel, plastic as well as wooden materials. It is the preferred drill bit choice for a majority of drilling applications.
  2. Cobalt(HSCO): Cobalt is regarded better than high-speed steel drill bits because it can help in drilling precise holes into tougher steel as well as softer stainless steel materials.
  3. Carbide: Carbide is the most robust drill bit material and is the most brittle as well. These drill bits are perfect for drilling into the toughest materials. It is not advisable to use them in hand drills and drill presses.
  • Length of the drill bit: Depending on the accuracy and precision of drills required for the job, you can choose drill bits of shorter or longer length. Shorter drill bits can do the precise drilling. They do not break down quickly and can be used for long periods even in tighter spaces.
  • Coatings on drill bits: Drill bits are coated with TiCN (titanium carbonatite, blue-gray color) for better wear resistance and Black Oxide (surface treatment) for mainly non-ferrous materials. Black oxide treatment aids in minimizing frictions and helps in abetting the chip flow.

You can maximize productivity by investing in drill bits which can complement in fulfilling your project requirements. Selecting the right drill bit can also help in improving the longevity of the tool as it helps in increasing tool's performance without putting any unwanted stress on the tool.
