About Us

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
