For sale is a 4" X 7" Permanent Magnetic Chuck for use with EDM's, Surface Grinders, etc. 4.1" X 7.05" Actual surface area of chuck top. Approximately 2-1/4" overall height. I have performed a basic test on this magnetic chuck and it is in good working condition. The top surface is very nice and shows no signs of abuse. This chuck was use to hold EDM tools on top of the edm and has no surface wear whatsoever. It was not used for grinding.
