Nova Chuck Jaw Sets

Item #
98% of 100

Choose the jaw set that best fits the needs of your turning project! Nova jaws boast superb holding power when matched with the appropriate workpiece. They cut into the wood, grip firmly in both contraction and expansion mode and provide high tear out strength. These jaws fit all of the Nova chucks, allowing you to interchange the jaws across all chuck models to achieve different capacities. Some jaws, however, are not recommended for use with certain chucks.

NOVA 100mm (4'') Jaw Set - JS100N (#: 46860)

The 4'' NOVA Jaw Set is designed for expanded dovetail or reverse dovetail use. Ideal for gripping footed bowls and mounting false (custom) wooden jaws. Not recomended for square spigot work.

NOVA 130mm (5'') Jaw Set - JS13ON (#: 49646)

Designed as the jumbo versio nof JS100N. Ideal for handling large work of up to 750mm in diameter. Suggested for use with both the Titan chuck and the SuperNOVA 2. Sugggested for use with centre saving systems.

NOVA 50mm (2'') Jaw Set - JS50N (#: 48239)

This versatile jaw is a standard with all Teknatool chuck versions and is ideal for those starting out before they move on to more specialized jaws.

NOVA 35mm (1.37'') Jaw Set - 6019 (#: 47711)

Designed for holding large bowls or moderate hollow forms it features dovetail walls that are three times the thickness of conventional jaw types. Allows for a gentle but firm hold.

  • Nova chucks give you the same jaw fixing system and same insert/adapter system across all chuck models.
  • All accessory jaws in the range will fit all the chucks in the range for optimum flexibility. Some, however, are not recommended. See individual jaws for recommendations.
  • Nova chucks are specially designed so the jaws cut into the wood, grip firmly in the contraction mode and provide high tear out strength.

Great addition to the nova chuck
The basic nova chuck was a great addition to my small lathe but the larger chuck jaws give a much stronger hold to larger pieces.

I have a king lathe with the base in iron and adjustable speed. Is this chuck with inserted or screwed on and also good for my lathe?
lucas on Feb 25, 2016
I have a Delta 46-461 chuck. Will these jaws fit to replace the smaller ones that came with my chuck?
Jim M on Sep 25, 2016
Will this chuck fit my shop smith?
Jay L on Apr 18, 2018
BEST ANSWER: Nova sells adapters that fit in the chuck and over the headstock of your base. You have to know what diameter is the threads of your headstock, then call Rockler and ask f there's an adapter for that size headstock
Can i put this on any lathe or no?
Blake P on Jul 12, 2017
BEST ANSWER: Probably. I don't know what type of lathe you have, but Nova makes many different types of threaded adapters that will adapt the thread on a Nova chuck to the head stock treads on different lathes. It is likely there is a combination that will work with your lathe. Look in your owners manual to find out what the drive threads are. Then find a Nova adapter that will fit that. The adapter will fit the Nova chuck. Then almost all Nova jaws sets will fit the Nova chuck.
Will these fit Barracuda Chucks?
S M on Apr 23, 2017
BEST ANSWER: I don't think so. Most brands are not interchangeable.

I have a SAGAR lathe with what I have tentatively identified as a 1 3/4 inch BSW thread on the headstock. Would the NOVA chucks be suitable?

William Martinson
William on Mar 31, 2017
BEST ANSWER: Hi William,
The Nova Chuck is threaded for 1", 8 t.p.i.
Best I can offer you I'm afraid.
Will these jaws fit an existing 100mm K11 chuck? (I'm planning on using them to mount cylindrical blanks on the 4th axis of my mill and no turning machine)
Marcus on Dec 20, 2016
I'm not familiar with your chuck but the mounting screws on the jaw sections are 18mm apart and the diameter of the hole through the jaw is 6.4mm
Hope that helps.
can i get a #3 chuck jaw for a "c" series chuck ?
H O on Nov 26, 2016
BEST ANSWER: I feel the correct contact with this question should be Nova. I am concerned about replacing one of four jaws in the set. they could also inform on availability. Rockler is a great store and Nova has fine quality products,

Will this work with Excelsior Mini Lathe?
A shopper on Aug 24, 2015
BEST ANSWER: With a nova chuck and the proper spindle adapter, yes.
do you have a chuck that will clamp onto the outside of a one inch plus ring that i can chuck into my half inch electric hand drill so i can polish the inside of the ring ?
chuck m on Apr 6, 2020
BEST ANSWER: No, we do not have a chuck that will do that.
will this chick work on a harbor freight mini lathe?
Ducksway on Feb 6, 2020
BEST ANSWER: It all depends on the size threads you have on your lathe. If it is normal standard threads you can buy an adapter, but if it’s some oddball thread that cannot be identified, probably not.
Will they fit on a shopsmith lathe? Mark V
David S on Feb 25, 2019
BEST ANSWER: The Shopsmith adapter is available for under $30 on this page. It must be 5/8" bore with a set screw to fit the Shopsmith spindle. To fit most chucks, you need the adapter to fit 1" X 8 tpi to fit into the chuck. Nova makes an adapter for the G3 which will fit both the Shopsmith and most other chucks. Happy turning.
I need a chuck that will fit a 1" 8 tpi set up, will nova chucks adapt to this? My lathe is a model 3420 by Wen.
Donald S on Jan 3, 2019
BEST ANSWER: Nova chucks are sold without inserts that match up to the drive spindle on your lathe. Nova has a wide selection of inserts. If you are buying the chuck used and the insert doesn’t match your spindle, you can either buy a different insert from Novaor buy an aftermarket spindle adapter. Ralph L 1/7/19
Would this Chuck jaw fit on a cheap tool shop benchtop wood lathe?
Patrick R on Dec 11, 2018
BEST ANSWER: These chucks connect to the lathe via insert, so it should, so long as you can cofirm the TPI & diameter of your benchtop lathe and buy the correct insert.
Will the 5” jaw set fit my Nova G3 chuck?
WHarrison on Dec 10, 2018
BEST ANSWER: I do not know about the 5" jaws, I do know the 4" jaws work.
I have a woodtek midi lathe will this fit on my lathe....and what else do I need to purchase?
David T on Oct 29, 2018
BEST ANSWER: I bought only the jaws to go on a Nova chuck. The Woodtek midi has a 1"-8tpi spindle I think. You need a Nova or Record chuck with the correct thread for your spindle; then the jaws will fit right on.
Will the 5 inch jaws work on a Nova G3 chuck?
Michael G on May 21, 2017
BEST ANSWER: 3 G chuck will only handle up to 4" jaws. you will need to get the next bigger chuck to use the 5" jaws
are the sizes the minimum jaw opening or maximum? i plan on turning pen blanks and am having trouble deciding.
A shopper on Aug 24, 2015
BEST ANSWER: The sizes indicated are usually the maximum opening. Generally, the minimum is around 1" smaller. I wouldn't recommend turning a pen with a 4 jaw chuck, however, I would recommend a pen mandrel. The will insure better alignment and stability.
