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.

Applications of flat type tungsten carbide flowdrill include: Workpieces where need to lengthen the thread; Multi-layer heat exchanger; Bearing support; Screw connection of stainless steel construction or metal furniture, etc.
According to the thickness of the workpiece to be drilled, there are two length specifications of flat type tungsten carbide flowdrills:
Short drill: Suitable for penetrating the workpiece having thickness of 0.8mm-3mm.
Long drill: Suitable for penetrating workpiece having thickness greater than 3mm-12mm.
