Flat type tungsten carbide flowdrill is a type of cemented carbide flowdrill that is divided according to the surface requirements of the workpiece. The characteristic of such a flat type flowdrill is that the flowdrill stretches through the workpiece to form a bush while cutting off the convex ring on the surface of the workpiece with smooth surface. Such a flowdrill is long lasting, stable and solid as the tungsten carbide is the most suitable raw material.

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.

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 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.

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.

Tungsten carbide hole saw is a special drill bit for processing circular holes in modern industry or engineering. The hole saw is attached to a drill, and used to cut large holes in wood, plastic, plaster, organic glass, or metals such as copper, iron, and stainless steel.

Tungsten carbide masonry drill is used to make holes in concrete and other hard, brittle materials, with characteristics of high precision, good wear resistance and high processing efficiency, and is often used in building construction and in some home improvement projects.

Tungsten carbide PCB drill is a tungsten carbide drill bit used for PCB drilling machine. Wherein, PCB, the short for Printed Circuit Board, is an important electronic component. Electrical or electronic components are generally soldered onto the PCB to both electrically connect and mechanically fasten them to it. The material of such a drill bit - tungsten carbide - has the properties of high rigidity, high strength, high hardness, high wear resistance, high hole position accuracy, good bending resistance, good breakage resistance, good hole wall quality and long life.

Tungsten carbide flowdrill is environmentally friendly, recyclable and solid to drill steel, stainless steel, copper, aluminum, brass and other metals. Such a flowdrill provides strong threaded connections for metric, imperial and gas threads.

Tungsten carbide twist drill is an excellent option as it starts drilling on contact for clean, accurate holes and are unlikely to lock-up on breakthrough. Such a solid twist drill can drill through a variety of materials, including plastic, acrylic, wood, aluminum, iron, copper, stainless steel, steel and other materials. It is suitable for electric hand drill, cordless drill, bench drill and magnetic drill. Here are some characteristics of tungsten carbide twist drill.
