These transverse bar pole chucks are specially designed for smaller, thinner workpieces and tool steel. The magnetic poles and coils run across the chuck, creating more pole area. This chuck, being special in design, offers superb holding power, but because they are custom made, we would only recommend them when careful investigation has shown that one of our standard chucks will definitely not fit the application. Selection of this design should only be made with the assistance of our Engineering Department. Model Smart Controls are recommended for all Walker Electromagnetic Chucks.
