For sale is four Collet EDM Chucks. Also included are Jacobs wrenches that fit those collets. Two of the wrenches seem to be covered by some hardened goo, that looks like perhaps it is the original preservative, or maybe something else. Also included are an extra threaded cap and more rubberflex collets. These chucks came from a cabinet with EDM supplies, so I think that they are for EDM.
