CNC bit is a type of metalworking tool that can be used for engraving and milling. It is like a drill bit, but instead of drilling holes, it cuts away material from the surface of the material being worked on. CNC bits have tips that are made from different materials, such as tungsten carbide or cobalt-chrome-molybdenum (CoCrMo) steel. These tips are either ground or machined to create a variety of shapes that can be used to cut different types of materials
CNC bits will cut through most metals with relative ease, but they do require specialized lathes to operate effectively. You can use a standard wood lathe with some modifications, but you'll need to purchase an adapter for your machine if you want to attach an HSS (high speed steel) collet chuck. A common way to attach HSS chucks is with a swivel handle attached to the chuck itself, which allows you to easily change out collets without interrupting your work flow.
