The chuck has a strong holding power because the tools lay directly onto the magnets and so you can re-sharpen very small pieces. The upper part of the chuck is made of BRASS, and that grants a longer life of the tool. The magnetic chuck can be both secured to any type of magnetic chuck and mechanically bolted by means of the four holes around the edges, aligning or flanking a number of chucks.

CMC magnetic chuck do not have two-layer switchable structure, that means the magnetic holding force always exists. So, if we want to remove the wordpiece from the surface, we should slide them to the edge and then take them away one by one.
