Round Type Tungsten Carbide Flowdrill

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.

The processes of stamping, or riveting or welding a nut are relatively cumbersome with high cost and low efficiency. Later, a process that changed the traditional drilling and tightening process - flowdrilling process appeared, making the previous processing problems (tapping and fastening of thin plate or thin tube) easily solved in seconds. The round type tungsten carbide flowdrill is just one of the drill bits required for this process, and the other is flat type tungsten carbide flowdrill. Tungsten carbide powder is a proper raw material for fabricating flowdrill as it has high hardness to make the drill bit have long working life.
