These jaws are designed to handle very large work up to 750mm in diameter. With these jaws you don't run out of capacity using Nova Chucks. An ideal companion to the SuperNova2 chuck as the extra power of the SuperNova2 matches the big capacity of these jaws. No need to consider larger chucks or faceplates.
Provision to mount false wooden jaws (so that customised jaws can be made for special purposes).
Jaw Travel Expanding - 127 - 147mm
Jaw Travel Contracting - 107 - 128mm
*Please Note - sizes listed above are when jaws are mounted to the Supernova2 Chucks - not recommended for G3 Chuck
