Ideas??

Have the retaining nut off, but the collet is seated really well---I'd rather not break it with a pliers--any tricks I don't know about?

Dremel brand and battery power, if that matters.

Ed wrap the collet tightly with masking/painyrts tape to compress the jaws. then use the crook (round gripping part) of the pliers to work it loose. It's worked for me in the past.
 
Ed:
Let is sit overnight with the collet facing up with a shot of Liquid Wrench or PB Blaster penetrating oil in the collet. In the morning, it'll slip right out. If it is really rusted in enough that PB doesn't completely loosen it, after it sits overnight, pull the collet end with hemostats.
 
Before you take a pair of pliers to it slip a bit back into the collet. It may prevent you from breaking off one of the jaws if you squeeze too tight.
 
I have also used a light tap on the end of the collet with a plastic headed hammer to catch it loose,

If it is a repeating issue -- replace the collet -- of if it is a problem with the socket, use the dremmel 3 jaw chuck to replace the collet. The three jaw chuck replaces all the collet sizes.

Usually a light application of lube and a cleaning takes care of the problem.
 
I used to put a drill bit back in (don't tighten) and rock it back and forth to
loosen the collet. But eventually I took Ken's advice.. get the keyless chuck
and ditch the collets altogether. The chuck is pretty cheap, maybe $7-8
 
Thanks to all!!!

I walked past a pair of lead snips (like very sharp wire cutter, made for stained glass artists), we have dozens that are not as sharp, they have been "not so gently" used.

So, inserted a bit to keep the jaws from bending, put lead snip as low as possible on the jaws and "pried" it up. Even after getting it "free" initially, the jaws did not want to come out (no, it was not rusted), seems the collet itself is very slightly oversize.

But, it is out and the replacement is IN, and I thank everyone for the different ideas. Always marvel at how many ways we can find to solve a problem----

THANKS!!!
 
Ed :
Being made in Racine IS the problem! It's so cold there that when they make the collets there, that they expand and stick when exposed to "normal temps"! If they were made in South Georgia (currently 104 degrees and 95 percent humidity), we could ship them to the South entrance of hell's asphalted parking lot and they STILL wouldn't expand.

Steve.. have you ever had a tooth drilled? That's just what these are,
although they're modified. (don't need that angle to reach the back teeth)
