Overview

Transform how you adapt your Nova insert-type chuck to a different lathe with the NOVA ILNS 1-1/4-Inch 8TPI Chuck Insert/Adaptor. Instead of purchasing a new chuck for every machine, you swap the insert/adaptor to fit a 1-1/4" x 8 TPI spindle. The adaptor uses external M38 x 3.5 threads to mate with Nova insert-type chucks, making installation straightforward and repeatable.

Crafted for consistency, this adaptor preserves your existing accessories and keeps alignment tight during turning tasks, helping you move between machines with less downtime and more confidence. It is backed by a two-year replacement warranty for added assurance.
