The monoset collet system on my Cincinnati Toolmaster is starting to be a pain. When
I am going back and forth between tool and dial indicator .. its painfully slow ..
unscrewing and screwing that big nut. I was thinking I could get another collet
nut and mill it down to where there is just a couple of threads .. so I could get it
on quick ... just for the indicator. Of course I would leave enough threads to
get a good seat for accuracy. Then use the full nut for actual tools.

So any Cincinnati junk boxes out there ... ?

At least with my old MT system .. I could just jam it up in there .. and just not
tighten the drawbar.

Unless someone has a conversion suggestion ...

What about making your own nut with a couple of threads?

lol ... I really suck at thread making ... and thats outside threads let alone inside ...

Point taken .. its just a weird nut .. with a swiveling insert on the end so that it doesn't
rub the collet.

There's not a Cincinati group is there .. ?

I was just roaming around and found your thread on this. Since I live in
Bridgeport country nobody here knows what im talkin about. Ya there is
a lot of threads on the big nut but thats good and ridgid. I am stuck with
a half inch collet I would like a 3/8 and 5/8 for my many end mills. I found out
they are "monoset" and I just found out to just loosen or crack the nut
and move quill up and that realeases the end mill. Before I was unscrewing
the nut (off) and slightly tap the collet to release. So where do Toolmaster
people find these collets spring type i think. Thousands on Ebay just confuse
me even more. Then I came upon a real life pic of one in a Hardinge Box on
ebay $40 looks real close but if not Im stuck with it. sam

Hey Big Job

Don't be confused .. you are looking for Monoset C collets. As you mentioned ... there are several
on ebay .. here is a seller for $35 shipped:


Wow .. I'll have to try that method to release the collet. Not sure how that works though .. I always
mill with my spindle all the way up and locked. Not sure how I can raise it any more .. but I'll look at
that today. I usually unscrew the nut till it is almost all the way off .. then tap the nut.

Saying you live in bridge port land .. just means that you live on planet earth .. lol. Fear not thouigh
what we give up in convenience and availability .. we get back in rigidity. That american made still of
yours can out perform most of those bridgeports.

BTW .. you should update your profile to say where you do live.
