This is an update to let people know what happened the original post is here:

I just broke out my new bosch router with plunge router base. It of course comes with 1/2 and 1/4 inch collets. Bits fit fine in the half inch but my 1/4 inch won’t fit at all. Even a 1/4” drill won’t fit in it. Anyone ever have that issue? I called Bosch and they’re going to send out a new one. The collet looks fine just a tad to narrow. I tried expanding it with a tapered punch but no luck.

The update:

The second collet was also too small. I was beginning to wonder if it was me or my router bits. I had split the first one with a pin punch and the inside split cleanly and allowed me to insert and work with a router bit.
So, I called Bosch and they were flummoxed. “We sometimes have a non fitting collet but the second one solves the problem. We’ve never had two not fit”. I said, “Well then it’s finally happened”. I had even brought the collet to the local hardware store to try a new router bit.. Maybe 1/4” had changed since I had purchased the last 1/4” bit?
They sent me a third collet, one that he had in stock at his desk and personally tried a bit into before he sent it out. My bits slide perfectly into it. They sent me a pre-addressed return label for the other two. I am gladly sending back the two bits to prove that murphy’s law strikes twice no matter what Bosch says.

BTW…. Bosch was gracious and kept sending them out.. kudos to them. And the plunge/fixed router with the attachments kit has been a dream to use after hanging up my 1970’s era craftsman router.

Every once in a while you will see a bad collet from different manufacturers, not just Bosch, but not very often. Glad they are sending you a replacement one.

Daniel,

I got my new Bosch 1617EVSPK kit about a month ago. Had not had time to begin using it until this week. Tried to install a 1/4” router shank into the 1/4” collet. Same problem as yours. I measured the opening and it measured 15/64” making 1/64” too small in diameter. Like you, I contacted Bosch and they are sending a new 1/4” replacement collet.

dalec, yup, That’s the one I bought the. Lots of router and stuff for the money. It seems to work well otherwise. $210 on amazon for router, plunge base, and kit that includes guide and a bunch of other stuff. Interesting that the router without the extras was selling for $209 I was in need of using it, and since they’re sending me out another collet, I took it off, put a tapered pin punch in the undersized collet and wacked it with a hammer. The collet split but would still accept the router bit. It tightens and is centered too. So, i was able to use it till the new one comes. It’s a bit unnerving though that a simple machined part has the wrong machining.
Oh, btw. If you’re reading that the motor is difficult to take out from the fixed to plunge base and back again on reviews on the internet. Just look at the guides and mechanism for awhile. It will then make sense and you can put it in easily every time. In fact the mechanism they’ve devised should insure not only fairly easy insertion but a really snug fit once locked into position along with good fine adjustment control afterwards. So, far I’m pleased. I went from a 1970’s era Craftsman to this… things sure have changed.

Daniel,

What a deal!

I thought about putting a cold chisel between the slots in the collet and giving it a wack. Sounds like the metal is too brittle to handle the bunt force trama (CSI talk).

With Bosch sending the replacement collet, I will be back in business shortly anyway.

Enjoy your new router.

Collet update: Bosch sent out a second 1/4 collet for my new router. It came in two days.. amazing. The problem is my router bits still won’t fit. I’ve got a 1/4” drill that I’ve checked with a drill guage and it won’t fit. I can’t even tap it in. The collet came packaged with the indication written on the packaging that it is a 1/4 collet for my router. So, I’m beginning to feel strange. Are my 1/4” router bits a 32nd to big. They are older but come from a variety of sources, some cheapies, some name brand. Has a 1/4” changed since I bought them?

I once had a problem with my Jet BS roller guides so I called Jet and they sent a replacement.
Wasn’t correct. I sent it back and they sent another.
The box was labeled with the right part number.
The plastic bag inside the box was labeled with the right part number.
The part inside the bag had a different number.
My guess is it was a vendor problem.
