How the Rare Earth Compact Milling Chuck Works:

This type of magnetic chuck is a manually operated permanent magnetic chuck. It is turned ON or OFF by turning the actuator shaft 180 degrees by means of an Allen key. The chuck is independent of any external power supply during operation. This offers safety, constant holding power, accuracy and no heat development causing expansion.
