Drill bits come in many shapes and sizes to meet the needs of every type of project. Micro drills require bits that are particularly small, which allow the user to finely drill the exact hole they need. In this video, you will learn all about the process of how micro drill bits are made. You will be able to see how different sizes and shapes can be created, and the entire process from start to finish.
The process begins with a blank, which is simply an uncut piece of metal that serves as the foundation for the bit. After it has been carved down to the desired sized, rough edges are smoothed out before getting cut down even more to exact specifications. The bit then finally gets carved to the exact desired shape, which can be as thin as human hair. The machines involved in this process need to be precise, and there are quality control checks. If you would like to watch this process for yourself, be sure to watch the video.
