High precision tungsten carbide flowdrill is well known as a drilling tool that can process holes on thin workpieces such as thin plates and thin tubes with advantages of high accuracy, high speed, beautiful surface, and low cost. Such a drill bit is wear-resistant and high-temperature resistant to be used at bad conditions. This drill bit uses the basic principle of generation of heat by friction to drill holes with bushings in tubular or plate metal workpieces, which is a preferred solution for thin-wall drilling connections.

High precision tungsten carbide flowdrill has five advantages - chipless, no need to weld nuts, enhance load bearing strength, save processing time, save production costs. Therefore, such a drill bit has been widely used to fasten thin-walled materials in manufacturing of automobiles, lighting, metal furniture, sports equipment, household appliances and bicycles currently. As the tungsten carbide flowdrill uses friction to generate heat, which is different from the traditional drill bit, so it requires high-speed machining. And it means that flowdrill bit cannot be used for low-speed and unstable equipment such as electric drills.
