NOVA CHUCK INSERT/ADAPTORS

 

IMPORTANT NOTE

We only recommend the use of authentic NOVA accessories on your NOVA chucks.

Using copies or other brands and products on your NOVA chucks could lead to issues like run out, detachment or product failure. 

Doing so will invalidate the comprehensive NOVA warranty and most importantly, use of unauthorised accessories may be unsafe.

 

 

 

 

 

 

 

 

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

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. 

 

Features & 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. If you are not sure what lathe thread you have, see our FAQ on how you can identify this thread

In order to help you find the most suitable adaptor, we provide the following table for you.

The first refers to the list of insert/adaptors that we manufacture.  Check with us if your lathe is not listed, we update our inserts all the time.   The second table refers to the thread sizes which we direct thread into the chuck body - as such, these do not require insert/adaptors.  A directly threaded chuck body cannot be altered to an insert type body or another thread size once threaded, so it pays to be sure that your lathe thread size is not covered by the insert/adaptors first!  

OPTIONAL ACCESSORIES

Insert Spanner. Makes it easy to get inserts off and onto your chuck and lathe. Dual ended, sizes useful for other applications on Nova lathes.
