For a precise and fast drilling of light metals, you need a resistant and efficient drill bit. Before settling on a model of drill bit, you must consider many criteria such as the type of drill used, the finish material, and the workpiece.
Drill bits are characterized by the shape of their tip (conical, concave, cylindrical, and round) and their diameter. Each has its specifics. For example, a conical-shaped bit is more suitable for digging, notching, shaping, and sculpting non-ferrous metals and plastic. Depending on the model, it is also used for working with wood, rubber, tin, and fiber. To ensure the lifespan of the sander bit models, they are generally made with highly resistant materials such as steel and tungsten carbide. This is the case, for example, with drill bit models offered by Maxicraft and OutiFrance. Moreover, their teeth have an excellent chip extraction power.
