Default Bosch 1617 collet will not tighten bit

Hi gang

I'm 50 yr old hobbyist that has been dabbling in hand tools and power tools for 40 years. I'm not expert at anything, but know enough to be dangerous with just about any common power tool.

I own various things like a table saw, dual sliding compound mitre saw, drills, circular saw, reciprocating saw, sanders, etc, and am reasonably mechanically inclined - although not so artistically talented!

So anyways, when I opened up my new Bosch 1617 router and attempted to tighten a bit into the collet, I was a little perplexed... I have a brand new Bosch 85294M 1/4" shank roundover bit, and I can't get it to tighten in my new router. I also tried a Freud 1/4" shank forstner bit for the hell of it, because it was lying about, and it wouldn't tighten either.

So then I tried the Bosch 1/2" collet with a drill bit that has a 1/2" shank, and it wouldn't tighten either. So I think I have eliminated the collets and the bits from being the problem. Pretty sure that I've eliminated stupidity (at least, mine) from the equation also. This should be a no-brainer.

It seems (I speculate) that the collets are tightening down in the threads but the inside of the motor spindle is not tapered enough to provide compression for the collet leafs. If so, this would be extraordinarily bizarre - I have done a search on the web, and can find no indication of a manufacturing defect, and I'm hard pressed to believe that mine would be a "one-off" given modern manufacturing practices.

So... any ideas what is going on here? I'm stumped.

Brett, welcome to Router Forums, glad to have you join us, I'm positive the members of the community would be more than willing to answer any questions you have
Are you sure you have lock the collet in the nut ( push collet hard into nut should snap and lock) also just because the collet new does not mean the collet any good
I am sure some of the bosch experts can help you
again welcome

you may have hit the self release feature. it gives a false tight if you are not aware of it, in the tightening...
tighten (just very snuggly) the collet w/o the bit... loosen the collet nut, (you should feel the nut resist loosening - this is the self release feature) install the bit and PLEASE make sure the bit isn't bottomed out...
go for tight but don't go all gorilla on it...

NOTE: when the nut on 1/2" collet is tight very few to no threads are visible... 1/4" collet - 1/8 to 3/16" of threads are visible...

push come to shove what does the manual or Bosch tech have to say about it..

This would have been the week that I'd have finished chewing thru the restraints...
If only new layers hadn't been added....

Welcome to the forum Brett. There's always a chance that the shaft recess isn't machined properly. Most of that work is computerized these days and computers don't always get get it right. If you have exhausted every other possibility then take it back to the store and compare it to another one. When you slid the bits into the collets did it feel like a snug fit?

Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.

Thanks for the welcomes and suggestions folks! Friendly group. I'll swing by the local Bosch authorized service centre tomorrow with it. It really seems that the spindle was not machined properly. Even if I hand tighten the 1/4" and 1/2" collets onto the spindle, the collets do not depress even slightly. Really bizarre. I'll let you know how the service visit goes tomorrow... When you have eliminated the impossible, whatever remains, however improbable, must be the truth.
