Unable to remove router cutter from OF1400

[pgrbff]

The collet nut unscrews fully but the bit remains stuck fast. Any ideas on how to remove?

 

[Pedronicus]

Maybe loosen off the collet nut (not remove it) and lightly tap said nut from opposite sides at the same time with something like tack hammers.

 

[Jones]

Knock the cutter out with a bit of wood and hammer then WD 40 so it doesn't stick next time.

At the risk of stating the obvious, the Festool routers, and others as well, have two loosening points for the collet. If you turned the nut until it was loose, keep turning it and it will loosen again to free the cutter. This won't work if you bottomed out the cutter in the collet.

Sounds like the collet may not have been put in the nut correctly. To remove the cutter you may need to tap it out with a piece of wood or old screw driver (this may damage the cutter) if it won't come out add some heat possibly from a hair dryer. Give it a tap turn the cutter around and tap from the otherside.

When putting in future cutters ensure the collet is clipped into the nut and held captive, screw it onto the router and then insert the cutter and tighten up. To remove the cutter undo the nut with the spanner, it will become loose but need another couple of turns to pull the collet out of the tapered shaft and then loosen the cutter.

Hope all goes well.

Cheers

The collet was correctly inserted in the nut, infact the nut unscrews completely but is still attached to the collet.
The cutter wasn't bottomed out either
In the end, I placed the spanner behind the nut and tapped it out with a hammer, it came out with the collet still attached but bit now loose.
Still not sure why it jammed, it is a relatively new bit and apart from a bit of staining on the shaft it appears nice and smooth.

All I can think of is to measure the cutter shank diameter with a vernier or micrometer to see if it's measurably different from the (I assume) 1/4 or 1/2" that it's supposed to be.
Then check the collet and the threads on the nut and spindle for damage. As Peter explained above, the two should snap apart and snap back together after cleaning.

It’s a relatively new cmt bit. The writing is still clear and the surface not pitted. It isn’t the first time I have used it either.

Also to prevent bottoming the cutter, put a rubber O ring in the collet and let the bit bottom on that and then lift slightly before tightening the collet.

 

[Jarno]

This indeed, if you bottom it in the machine, heating up of the bit because of use will cause it to be very stuck. Removing collet and bit, and then tapping it in further might cause the jaws of the collet to let go of the bit.

The problem with bottoming out should not be a reason as most CMT cutters have a depth mark on shank but Mike Jhns idea is handy , The other thing to check is shank /collet are they both 12mm or 1/2" not trying to show you how to suck eggs but the best of us put things in backwards /upside down .

Could the stain be resin from the timber you last worked? That may have caused tackiness.
