Ideal for mini, midi, and smaller lathes or for smaller turnings on a larger lathe. The Nova Precision Midi Chuck is packed with features and uses the same accessories as the Nova, Super Nova, Super Nova2 and the Nova Titan Chucks (without the need to use an adaptor plate as required with older Compac Chucks). Fast action, only one turn to tighten makes it ideal for production turning of smaller pieces. Comes standard with 25mm and 50mm jaws (automatic jaw safety stop) and includes Woodworm screw.
