High Quality Tungsten Carbide Flow Drill

Tungsten carbide flow drill, also known as friction drill, is a type of drilling tool that can create holes quickly. Unlike traditional drilling methods that create holes by cutting through the materials, a tungsten carbide flow drill uses high-speed rotation and pressure to heat and essentially melt the material being drilled, which is then extruded to create a new section of material.

During the process, the rotating tungsten carbide drill bit creates friction with the surface of the workpiece, generating heat that softens the material around the drilling area. As the drill moves forward, it pushes the softened material aside and shapes it into a collar around the hole. The tapered shape of the drill helps guide this softened material into the correct shape for maximum joint strength.

Tungsten carbide flow drills are commonly used in a wide range of applications, including aerospace, automotive, and marine industries, as they can effectively join a variety of dissimilar materials such as aluminum, steel, and composites. They are highly efficient, produce minimal waste, and reduce the need for additional fasteners or adhesives, making them an attractive alternative to traditional riveting and welding.
