I just recent switched over to a spiral bit for trim work and jointing with my router, but I discovered an unexpected problem as I went to change bits for another piece of work. Unlike most other bits, a spiral bit has no shoulders at the bottom; in the past when removing other bits I’ve placed a wedge of hardwood under the bit and levered it up and out of the collet. Without this shoulder for leverage I’m having a hard time removing the spiral bit without actually putting a plier on it and running the risk of breaking its thin blades. My router is a 25 year old Craftsman model 315. Does anyone have any suggestions for removing spiral router bits?

I use spiral bits too on occasion and what I do is whack them on the side with a piece of wood, trying to avoid the citting blades, until it comes loose from the collet.
Not a real elegant approach, but it works and I really couldn't think of another way to do it. I am not familiar with the model you have, so I don't know how easy it will be to get at the bit from the side.
Anyway, I hope this helps.
Indeed that collet will keep its cutters, expect this to get worse.
Get that cutter out:
Stabilize the router, vise or whatever.
Clamp the cutter with a hand screw, hold the collet and squiggle up & down.
No handscrew? C-clamp the bit on the flutes with too thin pieces of wood on either side and yank on that for awhile. Sometimes you have to break the cutter too!

Usually the problem with Craftsman collets is that the bit wants to wander out, not hold them. 25 years old ! How often do you take the collet off and thoroughly clean and lightly oil it. Some WD40 and 0000 steel wool may work wonders.

Hate to say it, break down and buy a new router. The new ones have great collets that don't get stuck bits, much simpler to adjust, speed controls, etc. When I replaced my 20 year old router a couple years ago I was very pleased...
I ultimately took the step DanFromDetroit recommends, but I used to take the collet wrench and give the collet a sharp whack. I found that would usually make the collet loosen enough to make the bit come loose. Just don't miss and hit the carbide on the bit.
Thank you all:
With your advice and some effort I was able to remove the collet and bit by applying some penetrating oil, tapping the collet around the base and then rocking it back and forth against the stops applied by the lock-up.
