Tungsten carbide shield cutter is a type of tungsten carbide cutter applied for tunnel boring machines. Such a cutter is made of carbide materials (WC, TiC) of high hardness and high melting point, together with cobalt (Co), nickel (Ni) or molybdenum (Mo) as binding phase. Generally, the heads of these cutters is made of coarse-grained WC-Co cemented carbide.

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.

Tungsten carbide flowdrill is also called tungsten carbide fdrill that is environmentally friendly, wear resistant and high temperature resistant to drill hole with stability, high precision and beautiful surface. It provides a perfect solution for thin-wall drilling connection. Well, do you know what are advantages of tungsten carbide flowdrill?

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.
