This insert is Metric.
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.
NOVA has the widest range of insert/adaptors of any chucking system, giving you maximum flexibility.
Warranty: 6-Year Full Replacement
FEATURES AND BENEFITS:
- 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 to ensure maximum adaptability and flexibility for the user.
HOW DOES THE INSERT SYSTEM WORK?
The insert fits into the back of the chuck and onto your lathe headstock spindle. We have the largest range of inserts to fit many different popular lathe models.
The inserts are threaded both inside and out. The outside thread is made to fit into the NOVA Chucks. The inside thread comes in a variety of sizes, which one you need will depend on what lathe you have.
See the insert thread listing below for more details.
