REGO-FIX HK clamping nut?

Mitch Alsup said:
From the interior nut machining--it is clear that the new nut is designed just to clamp the collet and not to hold the collet as it is being inserted or removed from the collet chuck.

The front taper will push and align the collet on the axis of the chuck.
The only issue I see is that the collet may become bound in the chuck itself whereas the std nut would <help> pull the collet off the back taper as it is unscrewed.

I, myself, would give it a try. IF it works great, if not, you probably did not spend too much on it anyway.

I might try tightening down the clamping nut onto the collet chuck. I can imagine the collet, which is tapered, compressing enough to snap past the ridge that runs around the friction bearing inside the nut. To remove, I can even imagine unscrewing the clamping nut from the collet chuck. What I can't imagine is how I would get the collet out of the nut since the collet would be held tightly in by the friction bearing's ridge.
 
I was kind of teasing you but who better would know? I think we are all stumped

Many thanks for this video. It gets me closer to a solution, but no brass ring just yet.
My REGO is clearly labeled "HK/ER 32". It is just like the one he shows in the first series of nuts. It has a "friction bearing", but UNLIKE THE ONE HE SHOWS, MY ER 32 COLLETS DON'T "SNAP IN". They are a tad too large. I can't get the collet to "snap in" by hand. I would have to tighten the nut down over the collet chuck, forcing the head of the collet to contract enough to snap past the ridge of the friction bearing. If I did that (without breaking something), I've no idea how I'd retract the collet from the clamping nut.

What brand collets do you have. You should be able to stick one side in and pull it straight. Some imports may be a little over size on the od.
 
Mark suggested I contact REGO, and I took his advice. Here is the very classy response from Jon Harvey of REGO:

Good morning,

The HK/ER series of nuts is pretty old, we are thinking they came out in the late 90s or so. It is entirely possible that the design didn’t quite hold up over the years to match what we are not producing as far as collets go. Unfortunately we can’t really help as far as that specific nut goes since we really have no way to check and see the issue ourselves.

That being said, could you give me your shipping address? We’ll ship you our current friction bearing nut free of charge. It’ll have the same internal coarse threads and all that, however it would be the most current product and we would be able to guarantee it working with your collet. Hell, you’ll likely see an increase in clamping force with the newer design as well!

Let me know and we’ll get a nut shipped out asap.

Thanks, KD. My collets are by Maritool. They fit into clamping nuts with an eccentric ring but not into clamping nuts WITHOUT an eccentric ring.
 
That is how a good company should respond. Sadly, it is an uncommon thing nowadays but its nice to see. Thanks for sharing.
 
I am sure that the posting of the kind act by Rego-Fix here on H-M will be returned many times over by new customers looking for that kind of customer service. You reap what you sow...
 
Today I received the new Clamping nut from REGO-FIX. It is their latest: Hi-Q ERB32 for ER 32 collets. Just like the one that did NOT work for me, the new one has a friction bearing ring. UNLIKE the one that didn't work for me, the the lip of the friction bearing ring is ECCENTRIC and is marked with a dimple where you insert the tilted collet. Then the collet just snaps in. Then is closes down onto the threaded collet chuck. To get maximum gripping, REGO suggests using a torque wrench. For my LMS collet chuck hitched to a Grizzly 7X12, my pin-spanner works fine by hand. I tried it on some of the small diameters (like 0.083"), and I could not make the rod budge in the collet no matter how hard I tried.

Happy ending. My tool envy syndrome now has acquired a top-of-the-drawer swiss-made clamping nut.
