Thermal drilling is a process that uses friction to produce bushings in metal tubing and flat stock.
The combined rotational and downward force of our special Thermal Drilling tool bit creates frictional heat. The material is transformed into a "super-plastic" state, allowing the tool to displace material and form a bushing. These bushings are ideal for threaded applications, as the number and strength of threads is significantly increased. It is an excellent alternative to weld nuts or threaded inserts.
