NOVA IXNS Chuck Insert 1″ x 8tpi Reversible Thread
NOVA IXNS Chuck Insert 1″ x 8tpi Reversible Thread uses an easy and inexpensive insert/adaptor system on all its NOVA insert chucks (apart from chucks that are directly threaded). The insert has different lathe spindle thread sizes internally and simply screws into the back of your NOVA chucks. Once the insert is in place, you can then put your chuck onto your lathe.
