Nova SuperNova 2 Insert Chuck

Item #
94% of 100
The SuperNova 2 is a solid, powerful chuck, perfect for use on lathes with up to a 20" swing. It's an excellent, all-purpose geared chuck, suitable for a majority of users, and is packed with exciting, innovative features such as a fully sealed composite indexing backing plate and copper - infused jaw slides. Its patented gearing system delivers incredible gripping power. You'll find yourself turning longer, more delicate stems, as well as larger, rougher work that was difficult to handle before. The SuperNova 2 requires only one hand to operate. Using a ball-nosed hex wrench with a large handle, its easy to tighten. This is an insert chuck, and requires you to purchase a dedicated Insert/Adapter for mounting on your lathe. Includes a set of 2" (50mm) jaws.

Features of the SuperNova2 Insert Chuck:
  • Fully sealed composite indexing backing plate. Made from ultra tough Duracon composite, reinforced with stranded glass fibers for extremely long life in tough conditions.
  • Self-lubricating properties.
  • Unique indexing function built into backing plate.
  • Holographic sticker for NOVA authenticity.
  • Powerful geared grip with Tuff Lock™ Technology delivers incredible smooth, solid, vibration-free clamping.
  • Single-handed operation for fast, convenient mounting.
  • Captured pinion and ball-nose Allen key with large, easy grip handle.
  • Body made from precision machined 1045 high-tensile steel.
  • Able to take all Nova accessory jaws (except Titan Power grip, which is specially designed for the Titan Chuck).

Features standard on all Nova chucks:
  • All Nova chucks are four-jaw, self centering scroll chucks for fast, secure setups.
  • The four jaw design firmly grips both round and square wood.
  • Quality materials.
  • Precision machined in one operation from a solid steel block for optimal accuracy.
  • Polished self metal finish to allow for closer tolerances and accuracy.
  • Common accessory jaw fixing profile - compatible across all Nova chucks and accessories.
  • Jaw slides made from high-tech copper fused steel for maximum hardness, wear, and self-lubricating properties.
  • Special woodturning dovetail profile on jaws.
  • Auto safety stop feature - jaw slides can't protrude past the chuck body.
  • Comprehensive instructions.
  • Common insert/adaptor fitting is compatible across all Nova chucks.
  • Safe Lock™ Woodworm screw included for fast mounting of rough timbers.
  • 6-Year Warranty.

This chuck does what it’s been designed to do...hold well. Built strong, and the t handle tool fits without having to jockey it around like on some models.
Here’s the first bowl turned using the chuck.
Nice chuck...strong and smooth operation.

Great products!
This is my second Super Nova II insert chuck. They are great products for a decent price. Why insert type? I like to keep my options open? Who knows, some day I may be able to afford an American Beauty? Until then, I am very happy with my Teknatool Nova products.

Using bigger and heavier blanks.
Claude R on Feb 21, 2020
I needed a substantial chuck to handle larger projects on my Laguna 18/36 and this fits the bill nicely. I have used other Nova chucks with great success, and decided to keep it within the family.

I purchased the super nova chuck. This is the first time I have used this type of chuck, so what adapter will I need to purchase to fit my Rigid wood lathe? Thanks for your help.
Tony H on Feb 23, 2016
I have a Jet 1221 lathe. Will this work and what adapter do I need?
Paul P on Apr 12, 2017
BEST ANSWER: Yes it will work, get a Nova 1x8 adapter.
I have a powermatic 90 with a 1 1/2 x 8 tpi. Will this fit my lathe?
Chris on Dec 27, 2017
Will this chuck work on the excelsior mini lathe? If so, what special instructions, if any, need to considered?
George B on Feb 5, 2016
BEST ANSWER: Works great. Make sure to get the right adaptor, which screws into the chuck and over the lathe spindle. I use it to turn the lathe into a drill using a drill chuck where the tail stock live center would go.
Will this work on jet1642evs?
Jerry W on Mar 5, 2018
Will this chuck fit my excelsior mini lathe?
Marty F on May 30, 2017
BEST ANSWER: This will fit on the Excelsior lathe with the correct insert. However, it is a heavy chuck and you might think about the G3 series. They are a bit smaller and will put less strain on your lathe.
The G3 reversible is already threaded for the Excelsior and the G3 insert will need an insert
Is there a M33 x 3.5 spindle thread adapter for this chuck?
Hookdaddy on Nov 22, 2016
BEST ANSWER: No, although Teknatool lists 28 different adapters available for their chucks in their current catalog, this size is not listed, nor are all sizes stocked by all retailers.
Will this Chuck fit a craftsman 12 inch wood turning lathe model number 113.23850 circa 1972 spindles three quarter-inch 16 TP ?thank you
John G on Dec 5, 2017
Did this chuck work on general lathe ?
Bruno F on Dec 18, 2016
BEST ANSWER: Not knowing which model you are asking about, all I can say is that if your lathe has a threaded headstock all that would be necessary would be the SN2 & the appropriate insert, e.g., if the headstock is 1"-8tpi get the 1-8 insert, if 1 1/4 -8, get the 1 1/4-8 insert etc.
Can I fit this chuck on my Shopsmith?
Pat P on Oct 14, 2016
BEST ANSWER: I do not have any ShopSmith equipment therefore I am not sure what thread Shopsmith uses on your spindle nose. But that is the key question that must be determined.

Look up the specification sheet for your model shopsmith to see if they use a standard Acme thread such as 1" x 8. That refers to a thread O.D. of one inch with eight threads in on inch of length. Then locate a matching Nova Chuck thread on Rocker. Rocker also sells Acme thread adapters.
Enter an answer to this question.
is this super nova 2 1-1/4" x 8 tpi ?
Ray M on Jan 29, 2016
BEST ANSWER: I gave you the wrong answer yesterday. The chuck is 1-1/4 and I had to buy a bushing to make it 1". Sorry for the mistake.
will this fit a Rockwell/Delta 46-200?
Rumplestilskin on Jul 9, 2019
BEST ANSWER: Yes it will. You will just have to get the correct insert for your lathe. I have several of these chucks and have been very happy with the quality.
Is this a 4" chuck or 5" across. ?
Ronny on Mar 5, 2018
BEST ANSWER: The body of the chuck is around 4" across.
I have a Central Machine 12in x 36 Lathe what chuck would match up i am looking at Nova super 2---- what else will I need to turn pens and bowls ???---Thank you for your help
Billy on Oct 18, 2017
BEST ANSWER: Billy, The chuck will help with making bowls, but not with pen making. If you want to make pens, you'll need a pen mandrel (I use a mandrel that works with 7 mm pen tubes), bushings, and a tail pen unit which allows the 1/4 "rod of the mandrel to slide inside the tailstock.
will this chuck work on a lathe with reverse?
steven j on Sep 28, 2017
BEST ANSWER: Yes with a double threaded insert
I have a 1 1/4 shaft on an Oliver lathe. 8 tpi is this a fit or do I need some adapter?
Richard D on Dec 19, 2016
BEST ANSWER: Looks like you need the adaptor, the threads in the chuck are larger.
Hope that helps
What adapter do I need for a jet 1236?
Dennis S on Nov 22, 2018
BEST ANSWER: You need to know the thread size of your headstock spindle. Check your lathe manual, or look it up online.
I just made an order on the Delta 46-460 and want to know will this chuck fit? If not what adapter?
Dennis A on Nov 11, 2017
BEST ANSWER: In this question about the insert, you don't mention if you are using the super nova 2 (SN2) chuck nor do you mention the size of the insert. The Delta midi lathe has a 1" x 8tpi headstock. There is a "Delta" version of the nova chuck that is "only" 1 x 8, but I'm not sure R* carries it. I know I've seen it online @A*z*n though. If the chuck you are looking at is a SN2 then an insert is required (for the delta use the 1x8). Hope this helps!
If I purchase a Super Nova 2 and a set of Pen Jaws will they hold a 7mm Mandrel to turn the pen after I have made the blank ready in the chuck ???? Thanks for your time
Billy on Oct 18, 2017
BEST ANSWER: No, the Super Nova with the pen jaws will allow you to drill the blank out on the lathe.
The mandrel will have a #1 or #2 morse taper that will slip into the hole in the head stock spindle on your lather. You will not have the chuck on the lathe when you use the mandrel.
I have a 1.5 inch 10TPI spindle.Will this chuck fit my spindle?
Marshall T on Sep 10, 2017
BEST ANSWER: Marshall, My spindle has a different TPI and I'm not sure the Nova SuperNova 2 chuck you're considering will fit your lathe. You might have to ask another source to get more information. Dustin
How do you set it up for use?
Albert on Jun 9, 2017
BEST ANSWER: First thing you will need to do with this is get an adapter that fits your lathe. That is the threaded portion on the headstock. The most common is 1"-8TPI and 1-1/4"-8TPI. You will need to check your manual for the spindle size.
I purchased a ns2 chuck I have Jet 1014 what spindle adaptor do I need?
