Hello, I am finally giving up and asking for suggestions to solve my delima.
I have a 1/4” Dewalt trim router. In order to get the bit shaft into the collet I have to drive a small screw driver into the collet slot to slightly open it so I can start it on the shaft then put the bit/collet in my vice and squeeze the collet on. To get the collet off I fully loosen the collet nut, use a small screwdriver and hammer to tap under the bit to drive it out of the router. Then, back to the vice and clamp the collet nut upside down and use a small punch and hammer, drive the bit out of the collet.
This has made using my router totally unenjoyable :((

The solutions I have tried – - and none of them worked . . . .
Bought a new Porter Cable trim router – -
Bought several new router bits – -
Bought 4 new collets – -
Used fine emery paper to polish the bit shafts – -
Coated the bit shafts with Dri-Slide – -

Looking through a 10 X microscope there are zero scratches on the bit shafts as there should be if burrs were the problem – I am throwing in the towel.

Thank you for your suggestions
Randy

Are you saying you have the same problem
with the Porter Cable router?

I’ve noticed over the years that some 1/4”
router bits are harder to get in and out of
collets than others. I have chalked this up
to minor variations in shank size.

Same problem with the Porter Cable.
I have 6 ea. 1/4” collets and around 25 1/4” shank bits and have the same problem with all of them in any combination.
I am retired from the new kitchen installation business so about the only thing I use these small routers for is round over bits on small projects – at least that is where I would like to use them if they worked :(

I know that one thing you are not supposed to do is tighten the collet nut down without a bit in it. Not sure if this is the result but perhaps that caused your problem?

Most new routers have safety collets. When you loosen the nut it will only back off a couple of turns before hitting a ‘stop’. The bit is tight and cannot be removed until the nut is turned past the ‘stop’ releasing the bit for removal.

If the collet nut is removed it will not easily go on unless the replacement procedure is followed.

Hi Randy I think your router bits are oversize as far as having to open all the collects to make them fit, having problems getting them out, it may be that you’re bottoming out the router bit in the collect. Because router bits have tapered shanks and the last 1/8” or so is wide enough that many times router bits get stuck in the collet when shoved all the way down and have to be pounded out from the bottom to release the router bit.

Hi Randy,

Do you have access to a micrometer? Check the bit shaft. Sounds like they may be over-sized.
Is it a particular bit or set of bits? Check them all. I have had an issue with a small set I picked up at one of the large home centers in the past. If you find they are over-sized, return them.

I stick to Amana bits. They cost a bit more, but they seem to last longer & have not had any issues.

Never had that prob w/ my USA-made PC, but my Freud has the “safety” feature that Madmark2 described. Check it out.
Yep! I know that the Freud router is a dinosaur, but it still works like new. Hope it stays that way.

My Dewalt has that safety feature as well and is described in instructions that came with it. It sort of feels like there is something wrong with it if you don’t know it is supposed to do that.

Thanks to all who have replied so far. I will try to answer each suggestion -
I build experimental biplanes so I am very familiar with mic’s. My bits, which are a mixture of Freud / Amana / Sears bought over the last 20 years, all check out fine as per shaft size.
I have never tightened a collet without a bit in the machine.
I am familiar with the safety collets as I have a plunge router with one. My trim routers do not have safety collets
When installing bits I do not bottom them out. I always stay away from the radius at the top of the shaft next to the bit itself.
I am getting discouraged. I fully expected to read a reply and immediately slap my forehead and yell, “why didn’t I think of that?”
I don’t know what improvement a new router could make, I am sure it will have the same collet size as the two I have now but I may be visiting Amazon in the next couple of days.
For everyone who has spent all day thinking about how to solve my problem – THANK YOU :))
Randy

You might try taking of the bits you know has a problem in your router and try it in some else’s router of even to a store where they will let you chuck one of yours in theirs and see if it has the same problem.

You mentioned that you bought 4 new collets. Did you have the same problem mounting mounting the bit the first time you used them? If you remove the collet from the nut, do you have the same problem with having to pry it open to slide a bit into it? Did the collets come with new collet nuts or did you use the original nut with the new ones. Just wondering if the nut is the problem and is deforming the collet somehow.

That is a good suggestion. I will take a bit along with me tomorrow to the lumberyard and see if they will open up a new router.
I did have the same problem with the new collets from the very first time I tried installing a bit. In order to use a bit I have to remove the collet and nut, slide the nut on the bit then pry open the collet to get the bit shank started then to the vice to squeeze the bit further on to the shaft.
The new collets did not come with new nuts, I am using the same old ones.
Thank you,
Randy

Is it possible you may have bought metric router bits. 8mm shank bits are just slightly larger than 1/4”.
I use the PC trim router and I don’t have that problem.
Are the collets you got compatible with your router. I have different collets from other routers and they are not interchangeable.

Hope all works out for you

An 8 mm bit is larger than a 1/4” bit by .065” or 1/16” in diameter. I don’t think that is the problem.

Maybe it has something to do with the INSIDE of the collet, itself? Like dust & rust build up in there. That alone would make things too tight for the shaft to slide in. Plus, the more you pry on things, to “open them up” the greater chance it will break off…...

It might be a good Idea to check with one of the router’s manufacturers and see if they have an idea what the problem might be?
