Flow Drill Technology in Modern Manufacturing

Introduction to Flow Drilling Flow drilling, also known as thermal drilling, is an advanced machining process used to create strong, wear-resistant holes in metal materials. This method is widely used in industries requiring high-strength connections, such as automotive, aerospace, construction, and manufacturing. How Flow Drilling Works Flow drilling involves the use of a specialized conical drill bit, often made of tungsten carbide, which rotates at high speeds while applying pressure to a metal surface. The frictional heat generated softens the material, allowing the bit to penetrate and form a bushing without removing any material. This results in an extended, reinforced hole ideal for threading or fastening components. Benefits of Flow Drilling Increased Strength — The process forms a bushing, providing additional material thickness that enhances the load-bearing capacity. Material Conservation — Unlike traditional drilling, flow drilling does not produce waste chips, ...
