Tungsten carbide screw tap is the most mainstream tool for processing internal threads (tapping) as it has characteristics of high hardness, high strength, precise thread, sharp and wear-resistant cutting edges, fast processing speed, high precision, good chip removal effect and durability. And therefore, it has wide range of applications in tapping stainless steel, die steel, cast iron, alloy steel and carbon steel, etc. More details, please visit: http://www.tungsten-carbide.com.cn/tungsten-carbide-blade-bar.html Tungsten carbide screw tap can be divided into tungsten carbide straight flute…

Flat type tungsten carbide flowdrill is also called flat type tungsten carbide fdrill, which is an indispensable wear-resistant and high-temperature resistant drill bit with three cutting edges for fdrilling process. In just a few seconds, a fdrill made of high-quality tungsten carbide powder can process a drill hole with a bushing on a thin metal workpiece. The bushing can be used as a tapped hole or a bearing fulcrum. It can also be used for brazing bushings, or connecting gas…

Tungsten carbide fdrill is also known as tungsten carbide flowdrill, which is used in a revolutionary new technology – fdrill technology. Well, such a technology is well-known as a tapping and fastening solution for thin tube or thin plate where requires properties of high hardness, wear-resistance, and high-temperature resistance. Tungsten carbide flowdrills are divided into round-type tungsten carbide flowdrill and flat-type tungsten carbide flowdrill. And they can also be divided into long and short fdrills.

Round type tungsten carbide flowdrill is a standard flowdrill. The characteristic of the round type flowdrill made of high-quality tungsten carbide powder by certain processes is that the flowdrill penetrates the workpiece and stretches to form a bush while forming a convex ring on the surface of the workpiece. And the convex plate is suitable for thread sealing or nut washer. More details, please visit: http://www.tungsten-carbide.com.cn/tungsten-carbide-drill.html The processes of stamping, or riveting or welding a nut are relatively cumbersome with…

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. More details, please…

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…

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. More details, please visit: http://www.tungsten-carbide.com.cn/tungsten-carbide-drill.html Tungsten carbide microdrill bit is made of a tungsten carbide based cemented carbide which contains a binder…
