Overview of Flow Drill Application Areas and Major Companies Using the Technology
Information compiled from industry reports and publicly available data.
I. Core Technical Principles of Flow Drill
By generating high temperatures of 600-900°C through high-speed rotational friction, the flow drill locally softens metal materials to achieve chip-free drilling while simultaneously reinforcing the hole edge through flanging. Compared to traditional drilling processes, it reduces energy consumption by 80% and improves processing efficiency by 3-5 times.
