Flow punch forming with centerdrill is a process in which high-strength bushes or eyelets are produced in thin-walled metals using a simple operation without cutting. Instead, friction and feed pressure are used to heat and form the material. The bush can then be threaded using a Thread Form Fluteless tap.
