Teknatool uses an easy and inexpensive insert/adaptor system on all its NOVA chucks (apart from the Compac). 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.

• Adapts any NOVA chuck to almost any lathe spindle at low cost.
• The insert/adaptor versions of NOVA chucks all use the same insert/adaptor system
