NAGU 4-inch Jaw Set Fits all NOVA & Record Power SC3, SC4 Chuck

Seems well made. Fits my G3 Nova chuck perfectly.

I can't tell the difference between nagu and my novas. I've got three now, they all work great. From what I've read, the machine shops overseas that make name brand parts/tools, sell the same parts/tools without that brand at lower prices. Probably the case here. Either way, the chucks and jaws are good.

Perfect fit on Nova Chuck. Well made, fast shipping.

Don't expect machined steel, they're cast aluminum (?), so they don't run completely true but they work for sanding the bottom of a bowl after removing the tenon. I just got them so I haven't tried actually removing a tenon but it looks like they'll tolerate light cuts.As for the 2 sets of screws, the slotted machine screws are for attaching the rubber "bumpers" to the jaws and the inset hex machine screws are longer than the screws for attaching jaws to the (Nova G3) chuck, so use them to attach other jaws on top of the Cole jaws so you don't have to replace jaws a couple of times to turn a bowl, if you're brave enough to have all that spinning at once that is. I've tried fitting 2" jaws on top of the Cole jaws, and that works, but I haven't tried using them that way. Given that the Cole jaws don't run completely true, I doubt that I'll do that normally. Good reason to buy a second chuck, but changing the jaws for a hobbyist like me isn't that big of a deal and I can always batch turning steps to use the jaws that are currently mounted. Also depends on whether the bowl mounted with the Cole jaws has enough clearance for the added jaws. The Cole jaws say 600 RPM max but it isn't clear if that's always or just for when the Cole jaws are holding the workpiece.My first question was "How far do I tighten the bumper screws?" I arbitrarily chose to bring the end of the screws flush with the back of the jaws. That gives them full thread contact and brings the bumpers tight against the jaws without unduly deforming them. Seemed to work OK and nothing came loose sanding a couple of test bowls.Actually that was my 2nd question: the jaws have "Read manual before use" cast into them but all I got in the box was the jaws, rubber bumpers, and 2 sets of screws, but no manual, so my 1st question was where's the manual I'm supposed to read?

works very well

I needed to grip a larger socket than the 70mm jaws on my Nova G3 chuck could handle. But I couldn't justify the $75 or $80 for the few times it would be required for me - I just don't turn large bowls all that often. So this looked like a good option for me.These seem to me to be machined just as well as my smaller Nova jaws - I'm very impressed. Haven't used them to turn a bowl but beyond machining jaws aren't that complicated so I'm sure they will work fine.Others have said that the jaws didn't close properly, that doesn't seem to be the case for me - see photo. One thing that I do, even with the Nova jaws, is to install all 4 jaws with the screws loose, then tighten the jaws together on the chuck before the final tightening of the screws. That way any slight imperfections in the alignment will be corrected.

I bought these jaws after struggling to drill a centers hold on my drill press. I read the review and for the price I figures what the heck.After drilling 30 dead center holes in 5/8” pen blanks, I will say I’m impressed! Remember to drill SLOWLY, cleaning out the bit as you drill. And I’ve found that a short 135 degree jobbers bit works best.

Great product! Fit finish and operation are great!

Great product

Both products I ordered are of the highest quality and fit my lathe and chuck perfectly. Really happy with my purchases.

Great set of jaws for holding bowls. Wasn't able to use the supplied 20mm counter sunk bolts to also hold my other bowl jaws on top as advertised as they were 5mm too small. 25mm bolts would have worked better.

only one jaw type is included, all the other jaws on the product images: long once etc is a lie

Does what it supposed too. Well made. Will get a lot of use.
