This Set consists of our well-tried 3-Jaw-Chuck.
A second set of metal jaws - these can be re-lathed to an arbitrary diameter, in order to raise the concentricity accuracy for work pieces with the same diameter and a set of polycarbonate jaws with the same diameter, and a set of polycarbonate jaws for extra scabrously work pieces (i.e. pearls)
• Outside diameter: 12mm - 65mm
• Inside diameter: 1.8mm - 56mm
