What is working principle of tungsten carbide flowdrill? You know, tungsten carbide flowdrill is a wear-resistant and high-temperature resistant drill bit for flowdrilling processes. The flowdrilling process is a chipless machining technology that processes holes and bushes on a metal sheet or tube at one time. Such a process has completely replaced the process of welding and riveting a nut on a thin-walled workpiece. Therefore, it is necessary for us to understand the working principle of flowdrill.

Tungsten carbide center drill bit is made of high quality tungsten carbide with the advantages of high hardness, wear resistance, corrosion resistance, high temperature resistance, etc., so that the drill bit has the advantages of accurate positioning, quick cutting, good chip removal, and high efficiency. And therefore the center drill bit is mainly used for center hole processing on the end faces of shafts and other parts. More specifically, it is mainly applied for precise positioning of prefabricated holes and guides twist drills for hole processing to reduce errors.

Welded tungsten carbide drill bit is composed of a steel drill body and a cemented carbide shank welded to the rear of the body. Adopting tungsten carbide powder and cobalt powder as raw materials, the drill bit is fabricated by cold pressing, vacuum sintering and other processes. The surface of the hole processed by such a drill bit has a good surface finish, high dimensional accuracy and positioning accuracy, and there is no need for subsequent finishing.

Tungsten carbide microdrill bit refers to a type of tungsten carbide drill bits having a diameter of less than 3.175 mm. In order to make the microdrill bit have an effective drilling effect, a series of factors must be considered: such as various elements of drill itself, processing parameters, hole depth, installation completeness, and the structure of workpiece.
