HC Type II Rotary Electromag Chuck
This is the Type II - rotary electromagnetic chuck with a removable center cover designed to carry the magnetic holding derived from the chuck's innermost coil to provide holding action down to a 2 1/4" diameter. The height of this chuck is greater than a Type I chuck and there is an entirely different construction used around the innermost chuck body ring. Because of this, it is not possible to convert a Type I rotary chuck to a Type II rotary chuck.
