Keywords: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. Temperatures can reach 900 C for the tool, and 700 C for the work piece.
The material is transformed into a "super-plastic" state, allowing the tool to displace material and form a bushing. The height of the bushing is roughly 3 to 4 times the original metal thickness.

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. The bushing can also be used as a support hole for welded, soldered or brazed connections as well as for a load-bearing surface.
