Advantages Of An Ejector Pin

The ejector pin or also called as the pilot pin has 3 major functions while using with an annular cutter:

Centering: The ejector pin is exactly positioned to the center punch mark. Switch the magnet on and the machine and annular cutter are in the drilling position.

Oiling: By means of the automatic internal lubrication, cutting oil is supplied via the ejector pin to the annular cutter in just the right quantity.

Ejecting: In the final stage, the ejector pin, pre-stressed by means of a spring, pushes the core out of the drill hole made by annular cutter.
